So, i was a lurker and I'm not a good computer guy, so decided to come out with this topic asking for help. I have an R4 and EZ 3-in-1 mix with a 2gb sd card. I made a gba folder and a save folder in order to play some GBA games. So I put in Buu's Fury and Metal Slug Advanced and Super Mario Advanced 4 and these folders/files with weird characters started appearing. I tried deleting them, but it says "Cannot Delete File: Cannot read from source file or disk." I decided to ignore it, but there are like 6 folders and 6 files with weird characters that are undeleteable. Can someone help me with this?
