I am a Windows 10 user, and my document is at the default location c:\Users\name\Documents.
I created a vault on a NAS that has all the files from my Documents folder, and have cryptonmator open the vault automatically using Dokany. All is well if I set my mount point at any folder on my harddisk, except c:\Users\name\Documents. Why this is so? c:\Users\name\Documents\ is empty.
For now, my mount point is c:\Users\name\Documents\doc. This is not as elegant as I wish for.

I make sure that c:\Users\name\Documents\ is empty, including deleted desktop.ini before I run a test to get the above.
I really doubt that the standard document folder is completely empty and/or not already in use by your OS.
That is also what the logfile is pointing to.
If nobody corrects me, I’m afraid you have to select a mount point that is not a system standard folder.
