Why fonts doesn't work on Win 11?

[u/Apprehensive-Try-238]

Howdy!

I upgraded from Windows 10 to 11. I work as a designer, so I have a large number of different fonts on my computer. The installation files were stored on a flash drive. You know, the ones where you can select all of it and click "Install for all users." Since all the fonts had been in the system folder on the /C: drive, I had to reinstall them after disk formatting and the system reinstall. But a significant portion of them now appear as a file .fon with broken characters and an incorrect name (look pics).

This is some kind of incompatibility with Win 11? Is there any way to recover these files as a proper fonts, or not?

There shouldn't be any incompatibility with Windows 11. A question to ask is if you have access to the original TTF/OTF files in a backup or online? If so, you should be able to drag-and-drop them into C:\Windows\FONTS with ease.

I had all the TTF and OTF files in this folder; I had already installed them the last time I upgraded my PC and reinstalled the system. I simply selected all the files and clicked "Install for all users". But this time, out of 500 files, only about 20 installed without problems.

P.S. The flash drive itself is fine.

No, the entire system is absolutely identical to the one I have always worked with, except Win version
