Description davero 2019-03-05 23:05:35 UTC
Error after opening a file saved on a file partition formatted as exFAT. The lock file can't be generated so there is only read-only access of the file possible. When saving the same file e.g. on a NTFS-partition normal processing is possible. I have all the read and write rights on the exFAT partition and enough disk space available.

Steps to Reproduce:
1. save file on exFAT-drive
2. try to open that file

Actual Results:
Error message (try to translate it): The lock file for exclusive access by LibreOffice could not be created, as the rights are not sufficient to create a lock file in the save folder, or there is not enough disk space left there.

Expected Results:
read and write access possible (Surprise!)

Reproducible: Always

User Profile Reset: No

OpenGL enabled: Yes

On Win10 + LO 6.1.5 + exFat key, I don't reproduce this.
I created a brand odt file containing just "test", saved file, closed LO.
Then I opened the file, no error.

I did the same test with master sources (future 6.3.0) updated today.

Thank you for reporting the bug. To be certain the reported issue is not
related to corruption in the user profile, could you please reset your
Libreoffice profile ( https://wiki.documentfoundation.org/UserProfile ) and

I have set the bug's status to 'NEEDINFO'. Please change it back to
'UNCONFIRMED' if the issue is still present

Sorry for the late answer as I'm seldom in Windows.
Good news, the problem is gone without any needed action.
But I recall having troubles writing to that drive. Maybe Windows mounted it wrong... So no lock file could be created, which lead to the described problem.
Thanks Julien and Xisco for your engagement!

Thanks for the feedback, let's adjust status to WORKSFORME, as it's unknown what actually fixed the problem.
