OK, thank you for your reply.
Thats all fine and dandy how Kodi works but why can't I specify another drive letter to store this temporary thumbnail directory?
Why does it have to be on my C drive.
I would like to specify it to be on my F drive instead.
On another though maybe I can make a virtual linked drive and have this location be stored on my dropbox account instead of taking up valuable
space on my C drive.
I will make my C:\Users\<Username>\AppData\Roaming\XBMC\ directory a virtual drive on dropbox instead.
Anyone try it? I will tonight if there is no way to specify another drive

You must understand how Kodi works.

It will always create those folders and files as they are cached (mirror images if you want) of the artworks you have locally or/and the ones scrapped from the net.
Think of them as "optimized" ressources intended to be displayed as fast as possible.

For example my posters are in 2160x1440 (4K ready) in png uncompressed : they are 9MB each.
Kodi just can't use them as they are to heavy so it creates a resized copy of those poster in jpg format. They are located in the directories you spoke of.

Hope it helps
