Hi, I'm working on my master thesis and have all my files on a USB without any backup anywhere else. I always safely remove the USB from my laptop when I'm done, but when I openend the files for my thesis today, everything looked like the photo and I can't open any of them. The other maps on the USB are fine, it's only the thesis-files. Can anyone help me fix this? I'm working with Windows 11 and there are pdf, word, excel and Rstudio files on there.
