I use the Snapshot feature with different branches. After switching to a different branch I encountered a problem when trying to switch back to the original branch. I got some error message I unfortunately don't remember, because it didn't show up another time. Now when I try to go to that Snapshot, it says "An error occurred during reverting to snapshot. One of snapshot files cannot be open." I checked the Snapshots subdirectory and found that indeed every snapshot has 4 files, *.sav, *.pvc, *.pnd, *.mem. But the one I want to go to has no *.sav file. I didn't delete the file myself, but it is obviously missing. How could that have happened ? Sorry I don't remember the circumstances very well. Has someone else had this kind of problem ? Is it possible to get the Snapshot back running without the sav file ? Or does it contaion crucial data about the Snapshot ? Regards, Christian
