hmm ist such a long time I used OS1.3. I hope I'm not on thewrong way. Oly files with their coresponding xxx.info file will show up under workbench.
Open a shell/cli and type "list df0:" or "dir df0:" and you will see your files. wb1.3 didn't have a entry "show all files" like OS2.0x-OS3.x.
Don't use ffs to fromat your disk. Unless you create a mountlist entry for ff0: AND (!!!) copying the fastfilesystem from the newer OS aof the A2000 to the a500.
All fastfilesystem up to OS3.9 should be OS1.3 compatible.
