I’m using Joplin in Windows 7, 10 and Android.
I synchronize through filesystem using Mega.
The Android MegaSync application has trouble dealing with folders that start with a dot so the .resources folder is not synchronized.
I think that the synch folder is just for synchronizing so it does not make much sense to place hidden folders inside it.
I would like that the folders inside filesystem synchronization folder do not start with dot.
