Issue with sync.ffs_lock and Citrix ShareFile from a Mac

[CallSTAT]

Hi,
We're using FreeFileSync to get a local copy of our Citrix ShareFile, which we can then back up. ShareFile mounts as a CTXFUSE file system and your wonderful application is the only thing we've been able to find that can get a reliable local mirror - thank you!!!
We're having one issue - every the time the Sync runs, it tries to create the sync.ffs_lock file in the main Citrix "Shared Folders" directory. That directory is not writable, and thus FFS generates the following error:
Cannot set directory locks for the following folders:
Cannot write file "/Volumes/Citrix Files/Shared Folders/sync.ffs_lock".
EINVAL: Invalid argument [open]
We could just set FFS to mirror each of the subdirectories, but they may change over time and it would be significantly more reliable if we didn't had to change the FFS sync target folder, batch script, etc. when the subdirectories change.
FFS trying to put the sync.ffs_lock file in the directory also causes ShareFile to throw an error on every sync.
Is there a way to prevent FFS from trying to create that file, or from logging an error when it can't? This is a one-way mirror and this is the only machine executing it so we're not concerned about multiple simultaneous syncs.
Thanks for the help!

Set the LockDirectoriesDuringSync flag to False.

Thanks for the quick reply! For some reason I didn't find that when I searched!
