KDE thumbnail generator running wild ?

[Rog131]

Are there settings for kde thumbnail generator ? And where are they?

Konqueror/Dolphin puts preview pictures in the /home/user/.thumbnails/large/ and /home/user/.thumbnails/normal/. There was several thousand png pictures, about 2 GB. Oldest preview picture was from 2005. Is the kde keeping these forever ? No cache size limit / expiration date ?


I did find these:

KDE Thumbnail Generator: how do I turn this off?
http://www.mepis.org/node/6758

I'm not completely sure on this, but try KDE control centre > Kde components > file manager > Previews and meta data
then try turning off thumbnails.

Option 2
if the main concern is making a huge folder, you can cut the amount of disc space used down to a minimum 0.2 MB at the 'maximum file size' control

Hmm - i have 1.0 MB at the 'maximum file size' control.

I must admit that I hadn't even considered the size of my thumbnail directories until I saw your post.

I don't have an answer, although I now wish I did. The only thing I can suggest is to make sure that the "Use thumbnails embedded in files" entry is checked.

one simple way to to clean thumbnail cache is to run kcontrol; choose > Security & Privacy > Privacy
but 2GB cache is unexpected

Trying fix with this:

I made text file obsolete:

#!/bin/sh

#remove older than 30 days
find /home/user/.thumbnails/ -mtime +30 -exec rm -f {} \;

and put it in the /etc/cron.daily/ (anacron should run these scripts daily).


This should find and remove files older then 30 days.

More man find, man rm and man anacron.

I tried this from konsole in the form:

find /home/user/.thumbnails/ -mtime +30 -exec rm -i {} \;

This finds and asks, if i want to remove.

-f, --force
ignore nonexistent files, never prompt

-i, --interactive
prompt before any removal

Hmm - seems to work.

Good thought! Daily cleaning with a cron job will tame the thumbnail monster before it takes over the entire /home partition. The only thing I would add is, that the file should be created as root, e.g. "sudo nano /etc/cron.d/cleanthumbs" and the perms will need to be set to 755, e.g. "sudo chmod -v 755 /etc/cron.d/cleanthumbs".
