Trouble extracting large downloaded files, especially Data2.Cab

This is a strange issue but maybe somebody has some advice.  My friend constantly has issues on his Windows XP SP2 machine with extracting large downloaded demos / betas etc of games.  They always seem to fail on data2.cab files though!  He has tried reformatting etc but it never seems to help.  I'm wondering if there is something corrupted on his XP CD related to Zip extraction.  

Does anyone have any suggestions on possible troubleshooting or ways to fix this?  We've tried having him download the files from several different websites (Fileplanet, Gamespot, IGN etc) but either way he gets it it does the same thing which means it really shouldn't be his network connection corrupting it somehow - and why always in the same spot on the file?

He has also tried different internet connections, even downloading it from work, burning to DVD then bringing home to his machine to extract and it still fails.

Do you think installing a product like WinZIP 11 will help replace the corrupted ZIp extraction or has anyone else heard of other solutions to this issue?

Thanks,
Nathan

Depends what you are trying to extract.  That would probalby help us direct you better.

The extension  .cab is just a file suffix.  It doesn't mean the file has been compressed using the Microsfot Cabinet File standard.

There are a couple of large game files where the data2.cab file is deliberataley encrypted as part of the copy protection.

It is for example World in Conflict Beta, Neverwinter Nights 2 Patching etc.. Happens with lots of different games.  I'm just trying to figure out why his computer has lots of issues with this stuff, yet mine does not?

He does have Nforce motherboard, but the Nvidia Network Manager isn't installed so none of that crappy HW firewall so many report issues with.

Could be his download that is corrupt rather than an inability to decompress.  What connection type does he have?

To test, you both download the same files and then decompress them.  If it's the downloading process at fault then yours will unpack on both machines but your friend's won't work on either.

Can be related to drive errors and RAM problems as well.  If his PC is OK then he needs to check with his ISP or look at a download manager.

We finally got it working by decompressing using WinRAR with "keep broken files" checked.  The patcher for the game then seemed to fix whatever corruption there was.  Your suggestions are good though and we will try those out.  We have replaced the drive in an attempt to fix it before as well and that didn't seem to help.  I suspect it is the ram or the motherboard somehow involved.
