ICC Profile Toolkit adds an infotip to .icc and .icm files. The infotip will display the (internal) description, class e.g. monitor ,type of color space e.g. RGB, and the, of the selected profile.
How you see the infotip will depend on how you have your folder options set up.
The extension also adds a right-click context menu entry. This entry depends on the currently viewed folder in Explorer.
