Undelete 2009 replaces the Windows recycle bin with a catch-all Recovery Bin that intercepts all deleted files, no matter how they were deleted. Lost file? No problem! Use the Recovery Bin's Windows Explorer-like interface to navigate to the file, or take advantage of Undelete's powerful search capabilities. Right-click the file, select Recover, and the file is back. The Microsoft Office Version Protection functionality can even restore your earlier, saved over versions of Microsoft Office (Word, Excel, PowerPoint) files.

Undelete 2009 incorporates the innovative InvisiTasking performance technology. InvisiTasking is a revolutionary method for a computer application (Undelete) to perform its operations with zero overhead on a computer, effectively allowing it to run invisibly in the "background". These now invisible background tasks include:

Purging older files the Recovery Bin when it fills up.
Managing the common Recovery Bin
Securely overwriting free spaces using the automatic Wipe Free Space
Automatically adjusting the size of the Recovery Bin (more information below)

The Undelete 2009 Recovery Bin catches all files no matter how they were deleted, allowing you to restore them instantly with just a few clicks of the mouse. The Recovery Bin mimics the directory structure of your disk and includes a powerful search function, making it easy to find and recover files.

Undelete 2009 now automatically adjusts the size of the Recovery Bin to the available free space on a volume. If the size of a volume becomes critically low, Undelete automatically detects this low free space situation and reduces the Recovery Bin size. If more space is available, Undelete can protect additional files.

Undelete allows instant recovery of older ("saved over") versions of Microsoft Word, Excel and PowerPoint files. As you modify and save Microsoft Office documents, Undelete transparently captures versions of the file in the exact state they're in before they're modified and saved. This way, when a you need to go back to an earlier version of a file, Undelete provides that missing version.

Emergency Undelete is a separate utility included with Undelete 2009 (note, it is not included with Undelete trialware.) used to recover files, and their respective folders, accidentally deleted before installing the Undelete. As installing software (writing any new files) on a computer can overwrite the deleted files you want to recover, thereby making them unrecoverable, Emergency Undelete can be run directly from a CD-ROM/USB drive.
