It's just the process of generating an icon from a PDF takes a second. If there is a lot of them, then it's is most likely going to be more obvious. I have the same thing with very large image files. -- Regards, Kris Douglas.

If there is a lot of them, Just takes a second in the background is fine, as long as it does not block your getting on with things. If it is impeding your ability to click-ahead and get on with things, or pushing the computer's response time above the 100-millisecond time allowed by the GNOME HIG, then we should deal with that. -Paul -- ubuntu-uk@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-uk https://wiki.ubuntu.com/UKTeam/

Now I just get a column full of little red adobe acrobat icons, which is not so nice to look at but removes the delay -- which, in answer to the other replies, I emphasise is really quite considerable when the folder contains hundreds of pdfs; it takes maybe half a minute to find them all, and while it is collecting them, the slider for the panel slithers up and down, making it difficult to navigate to whatever file one wants. When opening a sub-folder located on an external hard drive, the process of collecting the thumbnails is slower still. I dare say there are other file formats which also seek to generate thumbnails by default, but it so happens that in my case it is pdfs. -- ubuntu-uk@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-uk https://wiki.ubuntu.com/UKTeam/

In my case, I assume, they were being collected from the pdfs themselves every time I opened the folders concerned. Is there supposed to be a cache for such things, analogous to the browser cache for images from web pages? I don't seem to have a directory called .thumbnail in my file system (I ran a search for it).

snip The thumbnails are only generated once AFAICT. Look in your ~/.thumbnail directory ;-) Al I agree - I have a LOT of pdfs and whenever I open that particular directory it takes a few seconds to display all the files - it's not regenerating thumbnails, it just seems to be ordering the files. I too had to disable the preview. It's a pity it can't be set on a per directory basis as it seems the preference is set on all directories. -- Patrick Bulteel -- ubuntu-uk@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-uk https://wiki.ubuntu.com/UKTeam/

I don't have enough pdf's for that to be a problem - but there's always a hidden thumbnails subdirectory in every home directory. And photos are fast to load the saved thumbnails every time and that's the same process. The only slight annoyance is when I plug my camera in. It takes ages to create the thumbnails from the SD card images, but they are essential to have.
