Multi File Tool for Windows

This tool from ElmueSoft works on a folder (and its subfolders) on your disk:

Set the attributes of all files and folders. (Read-only, Hidden, Archive, System)

Change the date of all files and folders.

Create a list as text file of all files and folders.

Calculate the MD5 signature of all files.

List binary and text version of all EXE and DLL files.

Search for duplicate (triple...) files. Also via network.

Changing the date of all files in a folder is very useful for archiving purposes: If you set all the dates of your MP3 files e.g. to the 1.1.2000 00:00 you will recognize the files, which where added since the last backup by their different date.
