In Windows placing .icon with this .ini file works-

[.ShellClassInfo]
IconResource=.FolderIcon.ico
IconFile=.FolderIcon.ico
IconIndex=0
InfoTip=
[ViewState]
Mode=
Vid=

    Not sure how it works on other file managers (or any DE), but for Dolphin you can create a .directory file with its content like:

    [Desktop Entry]
Icon=/absolute/path/to/image.png

    I think it’s more or less universal.

    Specifically for Dolphin, there may be a way to achieve the same with extended file attributes (getfattr/setfattr) instead of directories, but I don’t know the attr name for icons if it even exists.
