Unexpected DavException

Hello!

I am very happy with the Cryptomator (1.3.3), but there are some strange things about its operation.
Sometimes when I delete folders with file in it, first it seem to be okay, but when I see whats happened, the folder is still there.
When I try to delete again, an error says that It cannot be deleted.
When I try to open the folder, it says that there is no folder with name like that.

I searched in the cryptomator.log and I found this:

Thanks in advance!

Is it possible that you’re trying to delete a folder that is inside a shared folder? If yes, please check this GitHub issue and let me know if it helps: https://github.com/cryptomator/cryptomator/issues/645#issuecomment-369057554

I am using Google Backup & Sync, too.
My files are not inside a shared folder, just inside the google drive folder and which is syncing continuously.
In the Google Backup & Sync, the function of "Are you sure you’d like to remove the shared folder X and should it be deleted for all users?" is switched off, so I don’t get messages like that.

I am using Windows version, 1.3.3.
Now there are 3 folders which I can’t delete. And the number grows over time.

4

Is this issue easily reproducible? If yes, what are the exact steps?

5

Now I tried to reproduce so I created a folder. Then I wanted to delete, it seemed to be deleted, but stayed there. Created an another folder and tried to delete that, and it was successful. Then I tried to enter the first folder and file browser showed that it’s empty. Then I tried delete once more, and doesn’t get error message, but the folder stayed.
I created a third folder, then I created a fourth folder inside the third, and I tried to delete the third, and I can’t, but after trying to delete, I can’t open it. So now I have 5 unremoveable folder.

6

I saved the log which made while doing these tests, can I send it to you?

7

Thank you, you can send it to support@cryptomator.org. Nevertheless, we’ll try to reproduce the issue.

8

I send the email.

Thank you.

We’re going to fix this in an update.
