Thanks for your reply John! I'm not sure however what LNKFIL is? (is that a rom subroutine? I didn't finish reading "Hidden powers of the M100" yet :o) ).
Shortly after my last message the two files got swapped again and this time I made a copy of the directory structure using "savem". It took a few days but the files eventually came back to their original position and I saved again the directory structure so I could compare them. Here is the diff : http://pics.lefauve.org/M100-Directory-diff.png We can see that: - an empty file slot (file type = 0x00, used to be "TS-DOS") became "DIRC.CO" which is the file containing the corrupted directory, so that's normal - both MKAX.BA and PGKOD.BA entries actually exchange their address and nothing else (0x813c and 0x8785) So that's weird... Also I'm not 100% sure but I think I may have read somewhere that the REXMGR should be the first file entry in the list after the builtin ones (basic, text, telcom, addrss and schedl) and in my case. I cannot find this again and I may be mistaken but it seems there are two hidden files (types 0x88 and 0xc8) and a deleted file/unused slot (type=0x00) before the REXMGR entry. Could this be the issue ? John R.

So basically when I want to create a new empty bank I duplicate an entry without too many files and I delete them one by one. Could this be the reason I ended up with a corrupt structure ? (and those two hidden files?) Is there a better way to do that? At some point I emptied a bank image, and duplicated it with the name "EMPTY" trying to use it as a startup empty image but I got some issues so I stopped doing it. Also I'm not sure if it's related but when I make a backup in the REX bank (using Ctrl+B from the menu) I got two progression bars: one which says "copying RAM to image" and just after it's completed a second one without text. On most (but not all) of my other banks the second progress bar doesn't happen when I refresh the backup). I'm not sure there is a solution to the problem, so perhaps I'll try to backup/restore using mcomm or the REX bank as soon as I know what is the best way to get a new "factory empty" REX bank. I'd still like to understand what happened, though :o) Eric
