Works as advertised; essential for music disks

The app takes a while to complete a scan, particuarly with large USB sticks, and at times it looks unresponsive but your patence is rewarded with clean results without dot files. Essential for preparing music USB sticks for your car.

The best 99¢ I’ve spent

This app has made transfering files from a Mac to a Windows computer via a FAT32 formatted drive as easy as from Mac to Mac. It works!!


waste of $1. FREEZES when scanning at 10%.
