the .info is kinda like the "index" for the drawer, it's not an actual #?.info file. (#? is the Amiga equivalent of doog ol' DOS' * )
And yes, you can take any drawers .info and rename into anything else, keep the .info and it'll work just fine.
To create your own .info, use IconEdit from SYS:Tools under the Amiga environment (Workbench) (Normally, AmigaOS is installed on the Workbench partition, but whichever disk you boot from, will become SYS: for that session, untill the next reboot)
