Rename regions and audiofiles

Here is the problem:
I made a mistake. I named some tracks with name1?, name2?. I recorded some regions. Then i realized that i can not copy the audio files of those tracks to a usb stick (FAT formatted intentionally), because the “?” in the name is not allowed. Ok, my mistake. But renaming the regions does not change the names of the audio files and changing the names of the audio files, will lead to missing files.
Is there a way to solve this problem

Yes, zip the Ardour session folder and copy the zip to the fat32 device.

Thanks, brilliant idea.

You have a tool for that :
