GIMP 2.10 plug ins

[neurolurker]

Hello.  If by change or design (1) your resynth files were in a separate folder and (2) that resynth folder itself was placed in your user folder, it might be helpful to check from the GIMP main window:

Edit: Preferences: Folders: Plugins: ... your synthfolder ...

to make sure your synthfolder is specifically listed as a plugin folder for the GIMP program to find.

Navigating GIMP preference folders is similar to Windows.  Under the Plug-in Folders Banner click the left-most icon, the one with the + sign, and the the folder icon at the other end of the bar.
