66000+ little Thumbnail files in .cache - fragmentation?

66000+ little Thumbnail files in .cache - fragmentation?

Postby Darktrax on Wed Jun 12, 2013 5:46 am

Getting short on space, and looking for where 1.4GB of disk space in my home folder was being used, I find..
~/.cache/thumbnails/normal - more than 66000 of them!
OK - so delete them, but does the space ever get cleaned up to be contiguous ever again?

I am not expert at fragmentation, but I don't think it is something that has gone away, and my instinct is telling me that this cannot be good. Even if there was a scheme that kept the number limited to a reasonable stash of the most recently used, the joy of thumbnail previews has this price in small file creation.

HTG Explains: Why Linux Doesn’t Need Defragmenting

If fragmentation does occur, the file system will attempt to move the files around to reduce fragmentation in normal use, without the need for a defragmentation utility.


Wouldn't worry about it and do not apply what Windows partition needs vs. Linux partitions.
Apple's vs. Oranges kind of thing.

Just one little tidbit to add. I noticed when I first installed Linux last year, when I was searching some old cd's/dvd's for wallpapers etc, that all the folders I opened in my file mgr created a thumbnail preview. Great. But all those thumbnails are saved to disk even though I may never pop in that disk again. If I do something like that, searching, it might be a good thing do delete all thumbnails afterwards. Doesn't really take much time to recreate the ones on my hdd, and the new folder is clean again. Yea or Nea.
