Can not find older tmi textures in my user folder in 2025.2

Older TMI textures no longer appear in the user library in version 2025.2. If I open them in 2025.1.1, they’re still there. Saving the texture again makes it visible in 2025.2.

While that is technically a workaround, it’s hardly practical if you have a few hundred textures. Would it be possible to create a script to convert the outdated textures to the new format? It seems a bit much to have an intern spend three days manually resaving all the textures.
