.SVN-WORK File Extension
What is an SVN-WORK file?
Client-side cache file generated by Subversion, a version control development program; used by a Concurrent Versions System (CVS) to track program changes and updates.
Since SVN-WORK files are local cache files, they are only referenced by the program and should not be opened manually. They may be deleted if they become corrupted or the version resource is out of date.
