Title: Problem - Compressed screen files
Post by: ComSoft6128 on 14:03, 29 November 18
Hi,

Looking for some help/info.
While cataloguing some Romdos D20 disks from 93/94 used for the storage of 17K screen files I found that a large number (40%/50%) have a file type .SQR as opposed to the usual .SCR.
The file size for these varies from 11K to 12K so it looks like a reduction in file size of approximately 33% was achieved.

I would like to restore the files but unfortunately I can't remember the utility that I used to compress them 25 years ago.
I would never have processed the files individually as that would have taken up far too much time - so a utility capable of batch processing must have been available to me then.

The "Q" in the file type makes me think of various CPM programs that could be used to compress files but I'm sure it was an Amsdos program.

Any ideas?

Peter

Back then, the most efficient screen compressor was called Squeeze or something...
Cant remember exact name at the moment.. sorry!!

Yes, there are SQUEEZE.COM and UNSQUEEZE.COM. But also IIRC, NULU.COM can do this. The 'Q' in the middle of the extension indicates that 'SQUEEZE.COM' was used.  :)

Thanks for the replies.

Squeeze looks like the CPM utility that would be useful:

Anything on Amsdos file compressors?

Cheers,

The fact that it's called Squeeze and the file extension starts with SQ would suggest that this is the one.

The best I found is this one... CPC Turbo Cruncher (start CPCT on disc)

A time ago, I did compare anything 'compression' on the CPC. This one is by far the best.  :)
