Calibre hangs after using CCleaner

Wordsworth · 08-07-2011, 01:00 PM

Just discovered to my joy why calibre has been hanging on clicking Convert Books. I use CCleaner on a regular basis and after un-checking clean Temp Files the hang-up doesn't happen. I've browsed some folder locations and found some files starting with cal, among others. Although not cleaning the temp files stops the problem, I don't want to have the temp files folders bulging with megabytes over time, so which files need to be left in place to stop the hang-up on conversion?
Any comments much appreciated.

calibre temp files are all in a folder starting with calibre_versionnumber

And on a general note, deleting temp files that could belong to running programs is a REALLY bad idea. You should have temp file removal run only on startup/shutdown of your machine.

Finally you can control what directory calibre uses to store temp files via an environment variable. See the customizing calibre section of the user manual.
