Amiga OS4, virtual memory and swap partition..

I have a Sam440ep with 512mb of ram and a swap partition of 1Gb. Few days ago i tried to unpack a 250mb .7z archive. I was able to view the content of the archive using UnArc but when i tried to unpack it on my harddrive it wasn't able to do this because it run out of memory... So my question is: what about the swap partition? shouldn't it be used automatically by the programs? (in this case by Unarc)..

@nubechecorre

It should, but I think it needs to allocate the memory as MEMF_PRIVATE. I wrote the 7-Zip XAD plugin and I'm pretty sure it does do this and works with swap memory as I vaguely remember it being reported.

Are you using the latest version? xadlibinfo will give you this.


Edit: code is here, uses private mem and does it in small sections.
