Erg..
I had been trying to learn Script-fu to attempt t fix it myself, but that is not going well.
My heart skipped a beat when your link didn't work.
https://script-fu.github.io/funky/hub/pl...-Autosave/
Apparently the link has capital A's now.
I tried testing it, it didn't work for me.
It seems that it cannot create the "Autosave folder on my F drive..?
I created the folder for it.
I renamed it to "GIMP_Autosave".
I checked permissions.
I restarted GIMP to clear any error conditions.
I started GIMP "as Administrator" to see if that would help.
I tried to attach an image for you, but it erased my reply here, so I'm going to post this reply, then try to post the screenshot below...
Yeah, it won't let me attach a screenshot. here is the text of the errors it throws:
GIMP Error
Execution error for procedure 'gimp-xcf-save':
Error creating 'F:\Images\GIMP_Autosave\Concordia[720x720]\autosave_1.xcf': Error opening file “F:\Images\GIMP_Autosave\Concordia[720x720]\autosave_1.xcf”: No such file or directory
GIMP Error
Execution error for 'Activate':
Error: Procedure execution of gimp-xcf-save failed: Error creating 'F:\Images\GIMP_Autosave\Concordia[720x720]\autosave_1.xcf': Error opening file “F:\Images\GIMP_Autosave\Concordia[720x720]\autosave_1.xcf”: No such file or directory
UPDATE: I created the GIMP_Autosave folder manuallly, and the Concordia[720x720] folder manually, and it is now saving the autosave files for the test image in the correct folder on the F: drive!
Now.. why won't it create those folders for itself??
UPDATE2: I tested with an unamed image and an alpha-only named image, the issue is definitely that it cannot create folders.
I also note that if one image errors out, it does not autosave any of them, but that may be expected behaviour.
I also noted that I don't HAVE to shut down GIMP to clear the error condition, I can just disable autosave, then enable it again.
