Software settings


Right after the program's start, UFS Explorer is ready for use, with the most optimal settings enabled by default. However, you can modify these parameters at your discretion for more efficient utilization of the software. The Settings pane is opened with the "Settings" option in the upper right corner of the interface.


This pane is composed of multiple sections: the "Software settings" section (1) includes general settings for the program, the "Explorer (file browser) dialog" section (2) allows adjusting work with the Explorer component, the "Files copying: Customization of user interface behavior" section (3) and the "Files copying: Customization of target storage operations" section (4) contain certain parameters applied during the process of saving files, while the "Hexadecimal viewer" section (5) offers several settings for Hexadecimal viewer. The "RAID defaults" section (6) is available in the editions of UFS Explorer with the support of RAID and comprises some parameters related to reading and reconstruction of RAID sets.


You can click on a setting, and the program will show a hint explaining the purpose or functionality of this particular setting.


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


Software settings

Temporary files path

This setting defines the target folder for saving all temporary files, for instance, when the "Default file open action" in Explorer is configured as "Copy to Temp and launch". The change will be applied immediately.


This parameter allows choosing the language used in the program's user interface. For the change to take effect, the software has to be restarted.

Zoom user interface

This setting allows increasing the scale of the user interface for its adaptation to high-resolution screens. To apply the change, you will need to restart the software.

UI color theme

This option serves for customizing the visual appearance of the program’s user interface. The software can adopt the color theme defined by the host operating system, use the standard light color theme on a permanent basis or switch to a dark color theme characterized by a dark background and lighter text. It is necessary to restart the software for the change to take effect.

Process (include) Windows logical drives

This setting indicates whether the software will detect the currently available logical drives (storage partitions designated by drive letters under Windows) and show them under "Logical disks" in the Storages navigation pane.

Recognize (display) connected media devices

This parameter determines whether the software will identify various complex storage devices (RAID, NAS and others) currently connected to the computer and list them in the dedicated "Connected media" section of the Storages navigation pane. The given section simplifies access to such devices and different features associated with them – including automatic assembly, decryption, opening shared folders, iSCSI volumes, snapshots, etc. However, the recognition process takes some time, so enabling this parameter may result in certain delays.

Default FS policy for defective blocks

This setting specifies how the software will respond when encountered defective blocks during file system access operations. Under such circumstances, the program can immediately abort the read requests, mask the defect by filling it with a predefined pattern for continued access to the data, or ignore (mask) all emulated defects but stop reading when an actual non-emulated one is detected.

System memory size for file cache

This option allows setting the maximum amount of system memory allocated for file caching (under Windows). Such a limit helps to ensure that the cache doesn't consume excessive system memory and thus achieve a balance between performance and overall system resource usage, especially when processing large image files.

Explorer (file browser) dialog

Maximum records per page

The option makes it possible to establish the maximum number of objects (folders, files) presented on a single "page" of Explorer. You can define any value within the range from 1000 to 10 000 000. A lower value allows saving memory and increasing the speed, while a higher one – manipulating more objects. The change will be applied to the subsequent operations in Explorer.

Maximum search results

This setting allows defining the maximum number of objects presented in a search result returned by a single search operation performed using the "Quick search" or "Search for files and folders" tool. The value can be specified within the range from 50 to 50 000. The change will be applied to the subsequent search operations in Explorer.

Default file open action

The parameter makes it possible to set up the default action for previewing files in Explorer (using a double click, the "Enter" key, the "Open" option in the file's context menu or the "View" button below the thumbnail preview). The file can be opened in the program's internal viewer or copied to the folder for temporary files ("Temporary files path" in the Software settings) and opened with the default associated application installed in the operating system.

Display bad objects

This option enables you to decide whether damaged objects (folders, files) will be presented in Explorer, for example, for the visual check of consistency of the opened file system.

Display symbolic links

This setting defines whether symbolic links (when supported) are displayed in Explorer for navigation purposes. If not, only real objects will be visible.

Enable file status (validity) indication by default

This option allows enabling/disabling the display of a status for files constituting scan results in Explorer. Such a status makes it possible to determine whether the file start corresponds to the data of a known and valid type or whether it was imaged, depending on the configurations.

Don’t display folder metadata size

This setting determines whether Explorer will show the size information for the folder metadata – the storage space occupied by information about the folder itself, rather than its contents. Hiding folder metadata size helps to avoid possible confusion with the size of the actual files contained within the folder.

Files copying: Customization of user interface behavior

Duplicate file conflict action

This parameter defines the default action taken in case of presence of duplicate files in the process of copying.

Display progress of the entire copying job

This option allows enabling/disabling the indication of the progress for the process of copying files. When enabled, this function may slow down copying from non-scanned file systems.

Log conflicts

This setting defines whether the conflicts of duplicate files are logged by the software.

Write summary of copying to log

This parameter defines whether such details as the files count, their size and number of errors encountered during copying are saved to the log after the procedure is completed.

When object cannot be created

This setting can be used to establish the default action performed when a file or folder cannot be created at the specified target location.

When read error occurs

This setting provides several options for handling situations when read errors occur during the process of copying files. The software can simply abort the copying operation for the affected file, proceed with its copying alongside with other files and log the encountered error or move the problematic file to a "$BadFiles" subfolder created automatically in the target location.

Metadata filtering

This option makes it possible to enable/disable filtering of metadata objects during the procedure of copying files. Pre-defined types of metadata for files/folders can be optionally skipped (for NTFS system files, Synology folders, Apple resources).

Limit number of logged copying events to

This parameter defines the maximum number of records allowed in the file copying log. Its primary purpose is to prevent uncontrolled growth of the log and excessive memory usage that might occur during large-scale file copying operations.

When the number of events exceeds the maximum value

This setting determines the action to be taken when the number of logged events surpasses the specified maximum limit. The program can cease further logging, overwrite the oldest events in the log to make room for new entries or terminate the logging of events in the user interface and save them to a separate log file instead.

Files copying: Customization of target storage operations

Encrypted NTFS (EFS) recovery method

This parameter allows choosing the format in which encrypted files will be recovered.

Restore general attributes

This option defines whether the program will preserve the general attributes for the copied file system objects. Such attributes may include the "hidden" and "system" flags or Unix-style permissions associated with folders or files.

Recover extended attributes (named properties)

This setting tells the software whether the supported types of extended attributes (custom named properties) need to be recovered for file system objects.

Restore symbolic links

This parameter defines whether the supported symbolic links will be restored by the software and if so, in what form (as a link or a text file).

Deduplication of folder hard links*Only RAID Recovery, Network RAID

This option allows enabling/disabling the automatic deduplication of duplicate hard links to folders (HFS+). When activated, hardlinks to folders are restored to a special location and then get linked with the target (as hardlinks or symbolic links). If the target file system doesn't support links, the software will be unable to process such folders.

Deduplication of file hard links*Only RAID Recovery, Network RAID

This parameter defines the way hard links to files will be recovered: a file can be restored to a temporary folder and then hard-linked from each target location (provided that the target file system supports hard links) or a copy of such a file will be created each time.

Hexadecimal viewer

Default text code page

This setting allows defining the necessary encoding used by default for symbolic representation of the raw data content in Hexadecimal Viewer.

Data copy limit

This parameter specifies the maximum amount of data in megabytes that can be copied to the system clipboard in Hexadecimal Viewer.

Undo memory limit

This option allows defining the maximum amount of data in megabytes that can be saved to the memory for recording unsaved changes in Hexadecimal Viewer.

RAID defaults*Only RAID Recovery, Network RAID

Detect known RAID

This parameter defines whether the program will detect attached RAID sets and try to assemble the known intact configurations automatically.

Update incomplete RAID automatically

This setting specifies whether the software updates an incomplete RAID after its missing component is detected.

Open Microsoft Storage Space volumes automatically

This setting determines whether the available Microsoft Storage Spaces should be automatically assembled by the program.
