The SOS Client uses a cache file to keep track of the file status. The SOS client compares the file time in the working directory to the time the file was retrieved by the SOS Client.I did following:
1. delete cache files
2. SOS download a project
3. close SOS and delete the local folder
4. use VSS to download the folder
If the timestamp on the file is later than time in the cache file, the file is considered modified. If the file is checked out and modified, status is Edited. Status is renegade if the file is modified and not checked out.
If you simply place files in a working folder and don't retrieve them with the SOS Client, status can be Unknown.
Doing a get with VSS into the working directory can also cause Unknown or Renegade status.
For best results, use the SOS Client for your file operations, otherwise you'll get unexpected results.
