On KDE Plasma, accessing files that the user cannot read needs kio-admin.
Apart from it being way slower for writing to a kio-admin location than reading from it, it also times out a lot.
I suppose the best solution would be to pause the timeout if a long operation is running on the filesystem. But for the time being, is there a way to disable the timeout (needing to enter the password again) alltogether?
the timeout seems to be exactly 5 minutes
