Hi there
After an update I was asked to migrate my data into an updated version of my safe (“Tresor muss auf neues Format aktualisiert werden”). Since this I can not use Cryptomator anymore as I am stumbling about the following error everytime I am try to do the update (appears after ~15 Min):

java.nio.file.AccessDeniedException: Z:\Mein Tresor\d\HK\7B4CO6UVG3HSKEXKABOKHRECIUXPHZ\4766RAQZ6OFRR7QUKKLQ2ZNEJYQHASM3F56JYJTBGYJ6S=== -> Z:\Mein Tresor\d\HK\7B4CO6UVG3HSKEXKABOKHRECIUXPHZ\5_3oghnzixj-FFKXDWWkTiBwSZsvfJwmYTYT6Q==.c9r

Does anybody know what it is or how to avoid this? Side note: It is also no longer possible to access the safe through Android because after the login there is just an empty directory. Thanks.

The error already states the cause of the problem: Access denied.
Cryptomator tries to rename a file such that it complies to the new vault format, but fails because it is not allowed to access it.

Is the access to the file Z:\Mein Tresor\d\HK\7B4CO6UVG3HSKEXKABOKHRECIUXPHZ\4766RAQZ6OFRR7QUKKLQ2ZNEJYQHASM3F56JYJTBGYJ6S=== restricted in any sense, e.g. only the owner can change it?

Thanks for your help. The error was indeed not caused by Cryptomator but by RaiDrive which I use to remotely mount Google Drive so I get access to the Cryptomator safe without having all the data locally stored. I used this method for a couple of month now without a problem but within the last few days the RaiDrive team apparently added an option “write protection” I did not know until now.
