Yes - and it is the README-file. Did someone steal yours?

Sorry thought it was most likely a stuipid question - but in the heat ofhmoment everything seems to dissapear!

Is it the 'Ctrl F4' command or am I still way off?

The main reason I'm asking is to confirm this can be done whilst the install is still running i.e. doesn't stop the install

Yes it can be used while the installation is running.
If it does not work try mounting with "mount a a:\ -t floppy"

Hi Thanks for the great help.

Is there any way I can have all the files on the hard drive and swop between them in order during the install command?

The original programme was on floppy disks and as progress they call it meant that my current machines have no floppy drives 🙁,
I tried using the CD drive to do the job by mounting it to the A drive and having a stack of CD'd with only 1Mb of data on them but unfortunately something has gone wrong and i get an internal error stating the following:
Sys2.dat field 60 - this is one of the files on the first disk - is this due to the file being corrupted with the move or it recognising that it is not on the floppy drive as expected?

I still haven't figured out how to do this.
I have here seven disk images, six of them are 1.44 MB and one of them is a 720K image. The game is Sam & Max. I named them disk1.img, disk2.img, disk3.img etc.
I tried to do the following:

1C:\SAM> imgmount a DISK1.IMG DISK2.IMG DISK3.IMG DISK4.IMG DISK5.IMG DISK6.IMG DISK7.IMG -t floppy
2Using multiple files is only supported for cue/iso images.

So IMGMOUNT only let's me mount one image at a time, but I would need to swap disk images in order to install the game. So how do I do that?

Does it work if you do a

MOUNT A "\some\folder\somewhere\called\A" -t floppy

and then manually copy the files from a diskette into the folder followed by a CTRL-F4 to force DOSBox to rescan the folder?

Extract the contents of the floppies using winimage into one directory and install from there?

Neither of those work.
The installer finishes copying the data from the first disk without problems but then stops and asks for Disk2. Even if I wipe out the contents of the folder, copy the data from Disk2 into it and then update the directory cache it keeps on asking for the second disk.

Maybe you should just use ScummVM instead for this game 😀

Still have to get the game data files out of their installation packaging for ScummVM. 😉

The installer may be looking for labels on the floppy disks, in which case there might be no easy solution unless you can write out the images to floppies and use a real floppy drive (for that, mount the floppy drive such as MOUNT A A:\ -t floppy)
