UndeleteOnClick is a very simple to use file undelete / unerase utility for Microsoft Windows. It can undelete files from any NTFS or FAT (FAT 12, 16, 32) partitions, including from hard drives (internal and external), floppy disks, flash cards, Smart Media (SM), SONY Memory Sticks, IBM Micro Drives, Multimedia Cards (MMC), Secure Digital Cards (SD), Zip disks, etc. Any type of file can be undeleted, including NTFS compressed and NTFS encrypted files. It also gives an indication of the chances of recovering the file, e.g. Good, Fair, etc. The program is small enough that it can be run from a floppy disk or other removable media, e.g. a CD, flash card, etc.
It is not possible to guarantee that UndeleteOnClick will be successful in recovering your deleted files. If you wish to recover a deleted file now we strongly recommend that you do not read, write, change or delete any more files, or defragment your drive.
When Windows "deletes" a file, it is not physically removed. The file is still on disk, and may be recoverable, however, Windows makes the space occupied by the file available for writing. If you create a new file, or save a changed file, it may write over the 'deleted' file's space, thus destroying it permanently. Defragmenting your drive may also overwrite the deleted files.
Be aware that because of the reasons stated above, a file may appear to be recoverable but may turn out to be corrupted or unreadable. This is not a shortfall in the performance of UndeleteOnClick but a result of the way the Windows operating system handles deleted files.
