I've been running into issues with my PSP and MP3 player related to hidden files OS X leaves behind after access a volume and copying files, specifically ._ files. When playing files in a folder, the player confuses these as actual MP3 files and tries to play them. I know there are a few scripts and apps strewn about the next net, but I keep reading random post and reviews saying they are dangerous to use as they do not specifically "target" FAT or NTFS volumes. The only app I can find that seems to have any backing BlueHarvest, but it cost $17. Are there any "safe" apps out there of or am I better off manually deleting them when I see they are causing a problem?
