I would like to put in samj Gimp 2.10.21 some filter settings that I have in samj Gimp 2.10.14.For example for the filters: Colors / Curve, Colors / Shadows-Highlight, Colors / Tone mapping ... etc.
I looked in the "Preferences" folders and found in D: \ Gimp-2.10.14_Portable-32-64bit-Win \ Preferences \ filters, 72 files of this type:


Should I paste them in: D: \ Gimp-2.10.21_Portable-32-64bit-Win \ Preferences \ filters? Or should I do otherwise?

I've copied/overwritten filter settings often that way between my machines.

For each filter and each setting, maybe use this:

and export to D: \ Gimp-2.10.14_Portable-32-64bit-Win \ Preferences \ filters ????

but it's tedious and again I only have 72 settings .....

Edit:Nidhogg, did I correctly understand your answer: Do not paste the 72 files

Backup your originals if you are unsure. I have replaced filter settings many times by overwriting the existing files in the filters folder without any problems.
If you open one with text editor, you can see that they are just simple text files, and they don't link anywhere in your computer,
which means you can safely replace one with another. You could even write one without opening Gimp.
Here's an example of the component-extract, for which I have not created any presets
but it has 3 entries because I have chosen to save 3 last used settings in the preferences.

You don't need to export them from inside Gimp, that would be tedious.
The only exception I can think of, is a filter that was changed/updated with a new setting between 2.10.14 and 2.10.20.

# settings

# end of settings

Nidhogg!

I opened several "GimpGegl-gegl -..." files, there are not only the settings that I saved and named ... For example, for the "Exposure" filter, I saved a only setting, that of your tutorial "Color Sketch" but I have other lines:

# settings

(GimpGegl-gegl-exposure-config "2020-06-18 19:23:43"
(time 1592501023)
(black-level -0.001)
(exposure 0))
(GimpGegl-gegl-exposure-config "2020-05-15 09:36:42"
(time 1589528202)
(black-level 0.001)
(exposure 0))
(GimpGegl-gegl-exposure-config "nid_sketch"
(time 0)
(black-level -0.001)
(exposure 0))

# end of settings

I can delete these other lines and leave only:

# settings


(GimpGegl-gegl-exposure-config "nid_sketch"
(time 0)
(black-level -0.001)
(exposure 0))

# end of settings

but for a file of 1 KB it is useless, on the other hand the "GimpCurvesConfig" begins to be important.

Yes you can delete them.
But every time you open a filter, and use the sliders the ones with time stamp will be created automatically,
unless you make this change in the preferences.

thank you Nidhogg
I put "0" as on the capture.
