I've now finished mapping the disk blocks.

I have found your "file with no name". Actually, The file does have a name - it's three space characters!

Spaces are usually used instead of a filename when the file's icon includes the program or file name. The only example I can think of is Compute!'s Boulder Bob AmigaBasic game. (In this case, the program name is two space characters and the .info file has two space characters as well.)

I'll have to check the Installer script to see if it takes account of that.

The disk contains the following files and directories:
Code:
Directory "df0:"

The file with three spaces as the filename is shown with underscores instead.

As amiman99 says, the disk is about 44% full. All meaningful data are in the first 932 disk blocks.

If this is an image of an original disk, it shows signs of having contained an earlier version of the software to begin with, and this has been updated by copying later versions of the files to the disk.

An FFS-formatted disk is usually filled from the root block 880 to the end of the disk, and then from the third disk block back to the centre. Disk block 879 willl normally be the last to be allocated.

However, this disk has all the directory and file headers in disk blocks 882 and up (disk block 881 is the bitmap block), and the data blocks and list extension blocks (with a few exceptions) in the first half of the disk.

The second half of the disk contains most of the old version files.

However, I think the software is intact and there are no disk errors, so I'm assuming that there were no read errors when the ADF image in The Zone was dumped.

Tomorrow I will check the bitmap block and study the Installer script.

Edit:
@amiman99: I have just found the LHA archive you uploaded to The Zone! That has given me a second copy of the software to check the files on amigagenie's disk with. Could you upload your disk image for me too, please, even with its disk errors? I should be able to fix it by pasting in corresponding blocks from amigagenie's disk image if they match sufficiently well.
