Is it possible to set custom (any image) thumbnail to a file (on per-file basis) in Windows File Explorer?
Suppose I would like to assign real book cover image to e-book in *.txt
format.
Atleast in XP that I'm in you can go to Tools->Folder settings->Filetypes where you can edit the filetypes by pressing Additional settings and pressing Change icon to change the icon type. Thats not per file basis though.
