PostPosted: Tue 18 Oct 2005, 07:37    Post subject:  Very slow compression / decompression  

Hello;

I am finding that it is taking a very long time to compress and decompress files and directories on my machine. Compressing a 10 or 15Mb directory is taking about half an hour (and vice versa).

This seems to be the case whether I am using muzip, or tar from the command line (still getting used to guiTAR);

I run Puppy (Chubby 105) from the live cd, so maybe a problem with size of or access to /tmp? The machine (700MHZ, 256Mb) has Xandros on the hard drive, which does the compression tasks much more quickly (uses different version of tar and gunzip, I think);

any ideas would be appreciated;

thanks,

A

. . . see if there is a speed option in the programs

Do the compression from the command line and use a speed option

Maybe someone will tell you how Smile Not me, never compressed a file that big . . .

Try rezizing or check available disk size

Start / Utilities / Resize root

tsk tsk . . .
We don't do virus - we leave that to Microtheft
The closesest to a virus program is the f-prot virus checker to check your Windows HD for infestation.

The guitar program is not intuitive and Barry has written to them
I use it when it comes up by

selecting all
Achive extract
(give it a location)
It is easy once you get the hang of it
(though as always it could be easier . . .)

We did have another decompressor (which had a weird colour scheme) I think that is a pupget now

For compressing and taring files you can use Mtools.

If you are really lucky someone might write a script to drop a zip into an icon and unzip to somewhere of your choice . . .
