I think if your disk is full, or the temp folder is not writable, almost every application will start having problems, including your OS itself. FreeCAD using your systems temp folder is totally standard behavior, and I'm not sure allowing to change that won't cause more trouble than it fixes...

Audacity is an app that can generate huge temp files (like video-processing or disk burning apps), so it makes sense for them to offer such possibility.

My 2 cents...

In linux, the system saves the necessery space for itself, for root use. It doesn't have problems, when an application like Audacity tries to fill the partition.

Most application, nowdays, save the temporary files in the user's folder.
That would be, in " /home/username/.cache/freecad " .

Maybe this has to do with how FreeCad is compiled from source. It might be a packaging thing. I don't know.

One point is interesting. If you go to $HOME/.cache then you'll find the directory FreeCAD there. But it's definitely not us who write on there and I have no idea which application created that directory.

IMO it's not such a good idea to allow the user to change the temp folder (at least not via the GUI) and besides that this doesn't solve the issue reported in 0001237. What you need there is a clear feedback that something went wrong.

Currently, the default temp folder is expected to be /tmp but at the moment you can already define the environment variable TMPDIR to point to /home/username/.cache/FreeCAD. Maybe we could choose a better name, e.g. FREECADTMPDIR.

In my $HOME/.cache there isn't any "freecad" directory. I mentioned it earlier as to where the temporarily files should normally be.

I meant that if allowing the user to change the temp directory is not a good idea,
than you might need to consider setting the default temp directory in the "proper" location.

In the following link, someone called Juliano gives some "oficial" guidelines for linux.

These guide lines are not obligatory, but they must exist for a reason.

In the parameter editor a custom path can be set under BaseApp > Preferences > General. The key must be called 'TempPath' and of type string. FreeCAD needs a restart when changing this.
