I have been using SyncToy 2.1 on Windows 7 for last 6 months. I have data on two pen drives synchronized with folders on my PC. The program has been running without any problem so far. However, this morning I got the following error message while running
the program for one of the Pen Drives: "Exception during preview: An internal error occured in the synchronization routine." The sync process on the other pen drive ran wihout any problem. What could be the problem and how to erctify it?
