This freeware lets you format any USB stick with the desired file system. In order to make a USB stick bootable, for example to have a backup when the PC crashes, a tool such as USB Disk Storage Format Tool is needed. USB Disk Storage Format Tool views the USB stick like a normal disk drive and then formats the USB stick with the desired file system (FAT, FAT32, NTFS). With NTFS you can also squeeze out more storage, if you turn on the available data compression.
