If a file has been partially overwritten, it attempts to reconstruct as much of the file as possible with the remaining contents
Get My Files Back will allow you to recover critically important documents, or other files, which have been lost by accidental deletion.

These files may be lost by emptying the Recycle Bin, or using other deletion actions that bypass the Recycle Bin altogether. Such actions include Windows Shift-Delete, command line deletion, deleting excessively large files or using applications that delete files without the Recycle Bin.

When a file is deleted from the Recycle Bin, or if the recycle bin is bypassed altogether, the file can no longer be recovered by the Windows Operating system. The content of the file still remains on the drive, relatively intact, until the section of the drive it occupies is overwritten by another file.

Get My Files Back identifies the contents of such lost files on the hard drive and allows you to recover them. If a file has been partially overwritten, Get My Files Back attempts to reconstruct as much of the file as possible with the remaining contents. This will allow you to rescue at least part, if not all, of that recovered file to continue using it as needed.
