How to make Thunar regenerate thumbnails?

  • 772

I have a large collection on pictures which needed cropping, color balancing, autotuning, etc. Now Thunar is showing the old thumbnails and is very confusing because i can't visually separate edited pictures from unedited ones. How can i make Thunar automatically regenerate or create new thumbnails for the edited pictures?

    Remove all contents of ~/.cache/thumbnails/normal:

    rm ~/.cache/thumbnails/normal/*

    ...and refresh the folder in thunar.

  2. Deleting ~/.cache/thumbnails/* didn't seem to help in my case, I had to regenerate thumbnails by refreshing (Ctrl+r) each view in Thunar. That is, having the first set of files in view in Thunar, refresh, then scroll and select a file not in view, refresh, etc. until all files have been in view while refreshing. Of course it's faster if you zoom out (Ctrl+-) to have more files in view.

    It worked for JPGs, but the older thumbnails kept attached to raw (.NEF) files.

    I ended up using this more radical solution :

    rm $(locate thumbnails)

  3. Its required to delete both normal and large thumbnails:

    find ~/.cache/thumbnails/ -type f -print -delete

    -print will print list of deleted files and can be removed.
