From the developer:
TRSTools is a utility that makes it easier to work with virtual disk images. My TRS-80 emulators, like most emulators, use virtual disk images rather than actual floppy disks or hard drives. Virtual disk images are representations of floppy and hard disks and contain the same information as real disks.
