I have a R4i-SDHC, so I need to manually sort my files alphabetically. Drivesort was working for a while until the following was happening constantly: I definitely do not have 377 files and 270 folders in root. It even tries to rename my volume label into some random characters. I'm currently trying FAT Sorter 1.0.4 now, but what could be causing DriveSorter to do this? Does it not handle microSD cards near full capacity very well? This hasn't really happened until I started adding jenesisDS onto my microSD card. I'd just rather not have to reformat in Panasonic SDFormatter every time I want to add one little thing and spend 30 minutes copying everything back onto my microSD card. Edit: FAT Sorter just did the same thing. How much free space am I supposed to have to make sorting possible?
