If you're on a console use tee to redirect the output to a file, or use gpm to select some text off the screen and paste it in a file. > I suspect when the option to have them random or in order was > added, something changed in the way it looks at the directory.

I think I disabled it at some point but in any case I have not noticed it chewing up CPU since. Could it be the file indexer now needs to re-index all your images and it falls over itself due to the number and directory depth? Is possible to drop into a console or ssh into this PC when it's hanging to see what process(es) are taking up resources in real time? > My temporary solution, I pointed it to a small directory that only has a > couple dozen images in it. That seems to work.

If there is no discernible difference it may be the problem is not with the metadata, but with Plasma being able to parse all these files and their metadata. Gradually add images to find a number at which the problem occurs and back off from there. Not a solution, but a workaround. Another workaround, restructure the fs to have fewer layers, but keep the same large number of images to see if it process them without a crash. Do you really all 100,000 images? Is it worth keeping all of them, or is it perhaps time for some house keeping? Wait for new Plasam version to come out and perhaps report a bug if one is not yet posted. -- Regards, Mick
