How to add extra G'MIC Filters for use in GIMP on Windows 7
Copy the desired .gmic extension files to folder:
C:\Users\Username\AppData\Roaming\gmic
Notes: If folder gmic doesn't exist there, create it first. Username is your computer login username.
If GIMP is already running, on the main menu, start G'MIC by selecting
Filters - G'MIC
Press the Reload button and the additional filters should appear in the list.
When you exit GIMP and start it later, the filters will appear automatically.
Note: I copied the following files to my directory:

photocomix has the Steampunk Pencil filter that went missing from the EXE install.
