Deleted files recovery for Microsoft Windows
At present Windows operating system applies two file systems - FAT and NTFS.
FAT file system was developed for an old DOS operating system. Due to design simplicity and low reliability of this system it's mainly used now for most memory cards such as those represented in digital cameras, mobile phones and other portable devices.
FAT file system features rather good chances for recovery of deleted files that can be substantially reduced with file fragmentation. The more the file has been fragmented the more difficult it is to recover. If a file is deleted on FAT by emptying or bypassing recycle bin the system wipes information about its location. At the same time the data are not deleted immediately. File recovery is possible only on condition that it has not been overwritten. For recovery of deleted files from FAT SysDev Laboratories offer a variety of software products that will meet your needs and among them specialized software for FAT file system - Raise Data Recovery for FAT.
NTFS file system is the main file system for Windows. It's a default file system for Windows NT/2000/XP/2003, Windows Vista and Windows 7 distributions and the only one file system that is supported for disk partitions over 32GB.
NTFS features one of the best data recovery chances until the information on the disk is overwritten. The system provides high possibility for exact recovery of deleted files. If a file is deleted on NTFS its Master File Table record is marked as 'unused'. Bitmap of used space is updated to release used clusters. File entry is deleted from directory record. For recovery of lost data from NTFS SysDev Laboratories offer their multi-purpose tools to cover even complicated cases. Raise Data Recovery for NTFS is a product specially designed for this file system.
Note: Like any deleted data recovery, file recovery from these file systems is possible until actual disk space is re-used for a new file.
