What Did You Do - Version 3.0 A tray-based utility that monitors your system folder (usually C:\Windows), plus 3 optional folders that you choice and logs changes made. It can detect if a file or folder has been deleted, renamed, created, or if the attributes have changed. When a modification is detected, it's noted in a log file created for that date. If you take your PC to the shop for service, What Did You Do might assist the technicians by showing what events have happened in your file system Or, if one of your crucial system files gets accidently renamed, before you resort to reformatting your hard drive or reinstalling Windows, you can check your log files to see if the problem can easily be fixed by just renaming the file to its original name. What Did You Do 3 can also print out you log files.
