HELP...cannot delete my son's games on R4 card!!!

Some sort of files named "USBC╚)Ké." are showing up on one of my son's R4 cards, in the games file. There's 2 of them with that name and they look to be quite large.... 3, 489,792 KB and the other is 4,177,920 KB. I have tried EVERYTHING to get rid of them and it says "cannot delete file, cannot read from source disk or file". And I can't delete any of his normal games now. They just pop back on!
What the heck is going on?????

I tried my other son's R4 and it's fine!

HELP!!!!

 

i use a program called unlocker to delete things that give me trouble http://ccollomb.free.fr/unlocker/

 

... or maybe the micoSD is corrupted or something? Have you tried to format it?

 

how would I do that?

 

Google up a program called panasonic SD formatter. Or open My Computer and right click on your card icon and choose format... (If I remembered correctly)

 

Thank you SO much! It worked by opening my computer and formatting!

Good thing I copied my other son's R4 and pasted them on after formatting.

Phew!!!!

 

are you using a adapter that looks like a camera card?????

 

nice try but that's solved.
