3. Use of UFS Explorer Standard Recovery

3.1 Introduction

As has already been mentioned in sections 1.1 Overview and 1.3 Features, this application is an effective data recovery instrument intended to be utilized by both home users and specialists in this field to restore files lost from various common storage devices due accidental deletion, formatting, file system damage after hardware or software failures, etc. In this section the peculiarities of software usage are described and illustrated with examples. If you have questions concerning the implementation of certain procedures, please refer to the Appendix section to check whether the question has already been answered there.

3.2 Software settings

Right after its launch, the program is ready for use with the most optimal default settings. However, the user can modify these settings for more efficient software utilization in the "Settings" pane opened with the "Settings" button in the upper right corner of the interface.

UFS Explorer Standard Recovery screenshot

Each value can be changed by pressing the "Change value" button next to it. All the defined settings will be stored in the corresponding user profile folder in a special "ufsx" file. The software will not save any data to the operating system registry or configuration files (except uninstallation information, if applicable).

3.2.1 Temporary files path

This setting defines the target folder for the "View" tool of Explorer. The software will save all temporary files to this folder. More information can be found in the description of Explorer. The changes will be applied immediately.

3.2.2 Language

This setting allows changing the language of the user interface. For the change to take effect, the software should be restarted.

3.2.3. Zoom user interface

This setting allows increasing the scale of the user interface in order to adapt it to high-resolution screens. For the change to take effect, the software should be restarted.

3.2.4. Hexadecimal viewer

The settings included into this section define the default encoding in which symbolic byte representation in Hexadecimal Viewer is displayed and the maximum number of bytes copied via the system clipboard.

3.2.5 Explorer

The settings avaliable in this section establish the maximum number of objects presented on a single "page" of Explorer and the maximum number of search results returned by a single search operation. Lower values will save memory and increase speed while higher values will allow manipulating more objects. The recommended values can be found in the hint section: to see them, select the header of the corresponding field. The changes will be applied to all the subsequent related operations. In addition, it is possible to set up the default action for the "View" tool: the actions include opening in the internal viewer or copying the file to the temporary files folder and launching it using the default associated application.

3.2.6 Files recovery (copying)

This section contains all the necessary settings related to the process of copying recovered files: the default action taken in case of presence of duplicate files, whether such conflicts will be logged by the software, whether the progress of the process of copying files is displayed, what will be done if a file or folder cannot be created at the specified target location and whether extended attributes will be recovered (for HFS+).

3.3 Operations

On startup the main window of the program is displayed, which includes the main menu (found near the top), the storages navigation tree (a pane on the left side of the interface) and the workspace (main program area positioned to the right). By default, the workspace will show the "Storage properties" pane which includes various information about the connected storages: for physical disks – type, name, capacity, number of sectors, ID, storage geometry, for logical disks – start/end, number of sectors, capacity and various file system properties and extra recognized technologies in addition to the above mentioned information about the physical storage it belongs to. This pane may also be opened with the help of the "Show properties" tool from the toolbar above the navigation tree or the storage context menu option.

UFS Explorer Standard Recovery screenshot

To get access to the content of a storage, activate the required disk partition in the storages navigation tree or choose the "Explore content of this partition" in its context menu. Using explorer-style navigation you may navigate to a specific folder, find and select the required files using the "Define selection" tool and save them using the "Save (recover) selection" tool from the toolbar or using the "Save this object" context menu option for each of the files/folders.

Any file can be also "opened" after its activation with a keyboard or mouse. This will either copy the file to the folder defined as "Temporary files path" and opened with the installed associated program or opened in the internal viewer depending on the preferences specified in the software settings.

The tree includes two major containers: "Logical disks" which holds all available logical volumes and "Connected storages" which lists all connected physical devices, disk images and spanned volumes.

Storages operations

The "Open" item in the main menu contains two subitems, using which you can manually open a disk image or virtual disk or a block device by specifying its full path.

UFS Explorer Standard Recovery screenshot

The "Image file or virtual disk" subitem allows opening any supported disk image or virtual disk file.

The "Named device" subitem allows opening a physical storage by specifying its OS-specific device name. In Microsoft Windows, you may open a volume by supplying its mount point (e.g. "E:"). To access physical drives you have to run the software as a local administrator.


The storages opened in UFS Explorer can be closed and removed from the list with the help of the "Close storage" tool from the toolbar above the storages navigation tree or the "Close this storage" option from the storage context menu.

The "Refresh" item from the main menu resets the tree of attached storages: the list of attached storages gets updated and will include all detected storages, even the ones which have been previously closed (except for closed disk images).

The contextual toolbar for the disk contains tools for the search of lost data, loading saved scan result, definition of lost partitions and allows saving the content of a disk to an image file or view its hexadecimal content.

Disk partitions

A single physical disk may be divided into several partitions. The purpose of this subdivision is data isolation (from other data or OS), installation of different operating systems on the same physical drive, etc.

The software will show disk partitions under the corresponding "drive" element (including those with unknown or unsupported file systems). The name of a partition reflects the type of a file system applied on it or the implemented storage technology. The start sector and the total size are specified next to each disk partition. More details about a partition can be found in the storage properties tab.

UFS Explorer Standard Recovery screenshot

The file system icon will indicate its condition: a green icon means the file system can be accessed, the yellow one may signal problems, the red one states that there are problems and the gray one means the file system cannot be recognized. The padlock icon means that the volume is encrypted while the applied extra storage technologies also have their special icons.

The software does not display any information about the mount point of the file system. For example, drive "C:" may be displayed simply as an NTFS partition of a particular size.

A volume can be identified by the disk it belongs to, size, type or file system as well as by its files/folders content.

After a partition is activated, the software opens its file system in Explorer.

Creating a disk image

If a disk seems to have defects, it's strongly recommended to create its image and carry out further data recovery using this disk image file.

UFS Explorer allows creating a bit-to-bit disk image file of a storage using a special tool from the toolbar located above the storages navigation tree or the context menu option. For this select the needed disk and choose the "Backup data" tool or left-click on the storage and choose the "Save contents to image file" context menu option. The tool makes it possible to save a partial disk image by defining a data range in sectors.

UFS Explorer Standard Recovery screenshot

The created disk image files may be opened in the software using the "Image file or virtual disk" subitem from the "Open" menu item and be used for data recovery instead of the original disk.

Defining missing partitions

The software allows defining a missing partition both manually and by automated scan. To open a "Partitions" window for any physical disk, simply double-click this disk or select it and choose the "Manage storage partitions or regions" tool from the toolbar above the storages navigation tree. The tools for work with partitions will be available in the panel at the top of the opened window.

To define a partition manually use the "Define region manually by specifying range" tool from the toolbar. In this case the software may detect partition parameters (such as start, size, file system type) automatically, if this information can be recognized by the software.

UFS Explorer Standard Recovery screenshot

Automated search for lost partitions is available through the "Search undetected partitions by metadata" tool. If you have started a new scan, you should specify a disk range to be analyzed and the file system types to scan for.

When a file system of the given type is detected, the software adds it to the list of found partitions. The color of the icon will indicate the information about the partition state.

The list of partitions can be saved to the disk and restored later using the "Save list to a file"/"Load list from a file" tools. It's recommended to save the list of partitions after successful scan to avoid repeated scan after software restart.

To add partitions to the storages navigation tree of UFS Explorer you must select the needed ones using checkboxes and press "Finish".

Important: The information about the partitions which were not selected with checkboxes will be lost if you have not saved the list of partitions to a file.

3.3.2 Using Explorer

Explorer can be opened for a disk partition by double-click on it, using the "Explore" button in the lower right corner of the main window or with the help of the "Explore content of this partition" storage context menu option.

UFS Explorer Standard Recovery screenshot

Files and folders are represented in Explorer as sorted lists, containing file/folder name, type, size and modification date. You may re-sort the list by clicking on the column header.

To simplify navigation Explorer contains a quick navigation panel with the support of navigation by navigation history, navigation to parent folders or by using a full path.

The left side of the „Explorer" pane contains a tree of folders. When a folder is activated, the software navigates to this folder. When a file is activated, the software will either open it in the embedded viewer or copy it to the folder for temporary files and open it with the help of the installed associated application, depending on the preferences specified in the software settings.

You can save files and folders to a specific "local" folder by selecting them and choosing the context menu option "Save this object". To copy all data from a folder you may apply the copy operation for the parent folder.

Several objects in Explorer can be selected for copying by holding the "Shift" or "Ctrl" keys when selecting an object in the list.

If you need a more complex rule for copying files, use a "bulk copy" operation.

Explorer pages

If the number of files and folders exceeds the maximum number specified in the software settings, Explorer will use "Pages" to show all files. In this case, the "Previous page" and "Next page" buttons become activated in the toolbar and can be used for navigation.

Bulk copying

The option is activated by the "Define selection" button in the Explorer toolbar. This turns both the list of files and the tree of folders to to the "checkbox mode" so that you could select files and folders for copying.

UFS Explorer Standard Recovery screenshot

The copying rule is defined as:

  • a file or folder selected with a checkbox will be copied;
  • if a checkbox was removed from a file of folder, it will not be copied;
  • if a folder is selected, it will be copied with its content except for deselected files and folders.

Having selected all the required files/folders, press the "Save (recover) selection" button to start the copying process. The selection can be canceled with the help of the "Cancel selection" button.

Search for files and folders

The function is available as the "Quick find" field: just specify a sub-string of the file name in the search field. You may also use advanced search: the "Search for files and folders" tool in the Explorer toolbar, the "Find in this folder" folder context menu or the "Ctrl+F" keys combination.

Quick search uses a string as a part of the file name and uses case sensitivity settings of the current file system.

For advanced search, you may specify a full mask for the file name (including the "wildcard" symbols * and ?). You may also define a rule for the file size and for inclusion of files and folders to the search result.

UFS Explorer Standard Recovery screenshot

The search operation will run over all sub-folders of the selected folder until all sub-folders are processed or the maximum number of found objects is reached.

Data size

Before starting copying files and folders, it's recommended to evaluate whether the size of selected data matches the amount of free space available on the target storage. You may use the "Evaluate size and test" tool from the Explorer toolbar or the same option presented in the folder or objects group context menu.

UFS Explorer Standard Recovery screenshot

The tool allows both evaluating the size of data and testing file system consistency. If a file system consistency error is detected, it's recommended to continue with file system recovery.

Folders tree panel

The panel contains the information about the currently opened partition, file system and folder for fast navigation. If a folder is chosen in the left panel, it will be opened in Explorer; this feature can be used for fast navigation through different folders.

The folder context menu contains all the tools available in Explorer for the folder record. If Explorer is in the "bulk copy" mode, you may select/deselect folders from the tree by double-clicking them.

3.3.3 Recovery of lost files

Search for lost file systems was described in the section Defining missing partitions. This section describes recovery of lost and deleted files (including recovery of user-deleted files, recovery after format, file system damage, etc.).

Recovery of lost files is available as the "Start scan" button in the lower right corner of the main window, "Scan this stoarge (find lost data)" tool in the toolbar above the storages navigation tree, the "Scan this file system for lost data" button in the Explorer toolbar as well as the "Scan for lost data" option in the partition context menu.

Recovery process

Search for lost data in UFS Explorer consists of two parts: definition of scan parameters and the scanning process itself. The parameters for scan are specified in three major steps:

- storage region to be scanned (in most cases you should keep the default values);

UFS Explorer Standard Recovery screenshot

- file system types to search for and file name encoding options;

UFS Explorer Standard Recovery screenshot

- IntelliRAW management.

UFS Explorer Standard Recovery screenshot

Having configured the necessary parameters, press the "Start scan button" in the lower right corner.

The scan may take a considerable amount of time. After it is completed, the software will open Explorer and show the scan result as a new "Scan result" instance opened by default with the information about the type of the scanned file system, its size and its own folders sub-tree in the left-hand pane. The pane will also contain the currently opened partition and its folders for fast navigation. If any folder is chosen in the left pane, it will be opened in Explorer; this feature can be used for fast navigation between different folders.

UFS Explorer Standard Recovery screenshot

The folder context menu contains all the tools available in Explorer for folder record. If Explorer is in the "bulk copy" mode, you may select/deselect folders from the tree by double-clicking them.

Saving a scan result project

To prevent the loss of scan results caused by software or hardware failures, it's strongly recommended to save them to a project file. This way you won't need to scan the storage once again which could make difference for large and slow storages. The tool "Save scan result database" is available in the Scan result item context menu, and this action will also be suggested by the software just after the scan is completed.

UFS Explorer Standard Recovery screenshot

If you need to resume recovery after software restart, you will be able to simply load the scan result. This option is available from partition context menu as "Load saved scan result" and as the "Load saved scan result" menu option in Explorer.

UFS Explorer Standard Recovery also allows pausing storage scan, saving it as a scan status database and resuming it later. To pause the scan press the "Pause scan" button in the lower left corner of the workspace and save it with the help of the "Save current state" button. To resume this scan, press the "Resume saved scan" at the bottom left of the "Storage to scan" scan settings tab.

Saving recovered files

You can browse and copy files from the scan result just like those of an original file system. This means the required files and folders can be saved using the same tools available in Explorer.

Important: never save the files you've recovered to the source storage. The file data (contents) is still being read from the source drive and the software may overwrite them. Use a separate storage for copying the recovered data.

5. Appendix

In this section, the most common users' questions are answered. For any further information, please contact the developers of the software directly via contact form at: https://www.ufsexplorer.com/contact.php.

Does the software modify data on the source drives?

Source drives are opened in the read-only mode so the software is unable to modify the data.

What file system type is applied on my storage?

If a file system is supported by UFS Explorer, it will be shown in the storages navigation tree as a partition with a certain name. For example, for "NTFS partition", "NTFS" is the file system type.

Does it support an X file system?

This information is available in the software Anyway, this can be checked by running the trial version of the software.

How can a partition be identified in UFS Explorer?

Find the drive and the file system of a specific size. Anyway, you may open the file system in Explorer and check it based on the files it contains.

There are bad clusters. How can the data be read?

If data is very valuable, it's better to contact a data recovery service laboratory for data recovery. If data costs less than the data recovery service fee, you may use the software to attempt data recovery.

If there are file system errors, it's recommended to use the file system reconstruction tools of UFS Explorer. Anyway, it is strongly recommended to access the data from such a drive only via the free "Read-It-Once plugin".

An external drive was not recognized, what should I do?

A: Check the data cable connection type and whether there is enough external power for the drive (e.g. 3.5' drives cannot be powered via USB). To make the software detect the drive, make sure the operating system can recognize the drive as a device.

In Windows: right click "Computer" choose "Manage". Go to "Storage" and "Disk management". Make sure disk is listed.

In Linux and macOS there is "Disk utility" in the system applications section that can be used for the same purposes.

Important: if you have connected a disk from another OS to the computer running Windows, it's may ask for "disk activation". Decline this prompt to prevent data loss.

The OS recognizes the disk but UFS Explorer doesn't. What should I do next?

Make sure the software is started using a local Administrator user account (this is required to access physical drives).

If other disks (except the required one) are detected, this may indicate a bad cluster on sector 0 of the drive. In this case, the disk still can be accessed via the "Read-It-Once Plugin".
