Hi! So I'm trying to sync folder A to folder B, and sync the entire parent folder of folder B to folder C. When I set this up, whether with one batch file or two separate batch files, I get the error "waiting while directory is in use". Is there a way around this?

Can you post a screenshot of the error? It is FFS that is using it or some other program locking it?

FreeFileSync (FFS) by default prevents you from simultaneously running two syncs if there is a full or partial overlap between the left and/or right base location (or its subdirectories) of both syncs.
See the description for LockDirectoriesDuringSync.

From your description, its seems there is such an overlap.
The solution is to simply run the two syncs sequentially.
