sync.ffs_lock not cleaned up

[tomlut]

I use windows 10 task scheduler to run a batch job at 6am every morning that syncs some files from a server to a NAS.

<Command>"C:\Program Files\FreeFileSync\FreeFileSync.exe"</Command>
<Arguments>"D:\Documents\Scripts\FFSync\hassio.ffs_batch"</Arguments>


This is still working but since the last update there is a sync.ffs_lock file left behind every time this runs.

There are warnings in the log:

[06:32:33]  Warning:  Cannot set directory locks for the following folders:
                      "H:\"
                      Cannot read file attributes of "H:\sync.ffs_lock".
                      Error Code 5: Access is denied. [GetFileAttributesEx]

Having the same problem on MacOS with 10.11 with SMB, and it's particularly bad on Apple FS shares.
