I was browsing my NAS to do my regular clean-out of the Archive folder, and noticed an unexpected number of large files in the .sync folder
-rw-rw-rw- 1 rslsync rslsync 188M Aug 11 10:48 D233B45F14F6F166076263C4926E2212691D40DB.!sync
-rw-rw-rw- 1 rslsync rslsync 116M Aug 11 10:02 D2ABA7458EACF812165A67DFD3FA183CA4454365.!sync
14gb of them in total!
Are these just leftover temporary files that are safe to delete?
