Files deleted from a pen/flash drive do not go to the recycle bin, have you accidentally deleted some files from your pen drive? How to recover them? There are a lot of commercial softwares available to do the job. A freeware alternative is DataRecovery.
DataRecovery scans the drive you want to recover files from and gives you the option to restore them or wipe out completely. It can even recover files that you have deleted from the recycle bin of your computer.
Supports FAT12, FAT16, FAT32, NTFS. Also it is windows vista supported. It can wipe off the deleted files forever so that they can never be recovered again. The Interface is pretty simple to use just select the Drive to scan for deleted files and wipe or recover them using the options available.
There is no installation required. Just unzip the downloaded archive and run it. The complete application is less than 500KB unpacked; it will fit on even the smallest of USB thumb drives and run from there. But DataRecovery doesn’t assure that all files deleted can be recovered successfully. It mostly depends on your system/configuration. DataRecovery can be downloaded here.
