So, my friend doesn't know how to get ROM's for his R4. The past few months, he asked his friends. And im one of his friends. So i opened up Removable Disk(the memory card), I found 2 files. Not a game either. I can't seem to delete it also. The only reason i cared is because he was going with Cylco DS, only because it supported SDHC. So he gave me his 2 GB Memory Card. I have a 1 GB Memory. So anyway, the file, is called "*?ZR%░m%.Γ º" The way i got the name was selected the "Rename" option and copied and pasted. The "thing" is a type of folder. When i double click it, this comes up: *?ZR%░m%.Γ º is not accessible. The file name, dictionary name, or volume label syntax is incorrect". I don't know what the file contains. Onto the other file, im not sure what it is. It isn't a folder, its just some white icon. Name of the mysterious file: "}*╬o╒ r.æ]á" Now, i don't really care about this, if its hidden. But the thing is, its 2 MB's. Is this some sort of virus? My virus scanner found nothing. Not sure what it is. Is it safe? I mean is there a chance of it corrupting my files on the 2 GB Memory Card? Oh and its a Sandisk for choses who wonder. Plus, i googled "How to delete and unmeetable file" and there is this program called "Unlocker". It unlocks locked or private files. After downloading it, i tried it (right click on the file, that want to be deleted) and then choose "UNLOCKER". There are many options, i only wanted it deleted. So i deleted, but no luck. It came out, saying "Success! File Deleted!". No it did not. I scanned the file incase it was just a virus, but it wasn't. I need serious help here!
