Undelete Files - Overview

When you accidentally deleted files from your hard drive, usb flash drive or digital camera memory card, please stop any writing activities on the disk which contains your deleted files. Writing data to the disk may write over the content of the deleted files and make them unrecoverable. You may download and use undelete programs to undelete files from disk. If they have not been damaged, in many cases, the deleted files are fully or partially recoverable.

Undeleting files from disk usually does not require special user skills. You may download undelete software and launch it, then select the disk to scan for deleted files. If the undelete software finds the deleted files, you can select them, and recover the deleted files to a different drive. It is highly recommended to save the recovered files to another partition or disk, otherwise, deleted files you need may get unrecoverable.

Usually, undelete utility is able to undelete files that have been deleted in Windows Explorer using SHIFT and DELETE, or the deleted files went into the Recycle Bin first, but later they were emptied from Recycle Bin, or some big files were deleted without going to the Recycle Bin.
