yes, DOSDATA=UMB is just a shortcut to imply FILESHIGH etc. but FreeDOS file management is split between so called fnode's and SFTs. The fnodes take 70(fat16)-76(fat32) bytes each in ke2033. In CVS it's now 60-66 bytes. Maybe they can be reduced further. In any case these live in conventional memory. Fnodes are purely internal to FreeDOS, no other DOS has them; that's also the reason I can change them, since no DOS program exploits them. The SFTs (same as used by MSDOS, see RBIL) live in the UMBs and take 59 bytes each.
