Fanuc Archive Diff
The Fanuc Archive Diff plugin (menu VFanuc » Plugins » Fanuc Archive Diff) compares the files of two standard Fanuc archives.

Select a ZIP archive or system.va of an unzipped archive for both robots and press Compare.
A ZIP archive is unzipped to a temporary directory which is deleted automatically. When the robot names differ, the plugin asks before comparing.

Programs with differences have the Show diffs button which opens Fanuc Diff

Programs (*.ls) of both archives are matched by name; files present in only one archive are reported as missing on the other side, the message window lists every compared file with its checksum.
The Show diffs button opens the Fanuc Diff window for the program.

In the settings (wrench button) the user can choose which files are compared and add further files (e.g. sysframe.va).

You may also refer to Compare Files for the comparison of any files.
