This version runs under Windows 95/98/NT4/2000/ME/XP/2003.

You can compare two "Windows" systems against each other. You can use UNC paths to compare two NetWare SYS volumes against each other. Use it to manage source code, keep folders in sync, compare program output, and validate copies of your data. Beyond Compare can create a snapshot of a live directory structure, and compare it against the live copy at a later date. Beyond Compare helps you analyze differences in detail and carefully reconcile them. It commands a wide range of file and text operations, as well as script commands for automating tasks, such as: compare text files, compare folders, zip archives, ftp sites, update websites, merge code changes, compare program output and more.

I found that the software from the manufacturer's CD worked as expected, but the one downloaded from the web was different in nature. This tool is lightning fast, screaming through comparisons of two "systems". I have also compared two PCs file systems using this tool. It's also extremely well priced (around $30) and licensed per user, rather than per workstation. This one is a gem - hang on to it!"
