Optionally, you may want to transfer the .LIT files to the SYS: account and the .CMD files to the CMD: account for easier access. However, if you don't want to clutter up your SYS: and CMD: accounts, it is not required. You will have to specify the INMEMO: ersatz device whenever you access any of the INMEMO files though.
For example, to execute the INFREE utility, you would have to type:
.INMEMO:INFREE
Or to execute the MAKMMO command file, you would have to type:
.INMEMO:MAKMMO
Actually, this is a small price to pay for keeping your disk well organized, especially since you would probably set up a menu system to access the desired utilities anyway.
