I need to compress some files in a folder, but my system denies me access from doing so.

Since they are system files, how can I compress these files without changing the permissions?

I'm looking for some approach that would in essence ignore the permissions, can this be done from the installation medium or do I need to fetch myself one or another boot CD and do it from there?

Please keep your do-not-compress-system-files comments at home, thank you!

You may know all the reasons not to compress system files, but for the benefits of others who might read this question: Do not compress system files. If you do, you can get into a situation where files that the system needs to read in order to decompress files are themselves compressed, leaving the system unbootable or in various states of unusable. – David Schwartz Apr 24 '12 at 9:17
@DavidSchwartz: I'll debug that case if it would happen. :) – Tom Wijsman Apr 24 '12 at 9:51
If it were easy to ignore permissions, then malware would have an easy path to root privileges. You might be able to do it from a ERD commander boot cd, not sure. – Moab Apr 24 '12 at 11:10
@Moab: Well, inside the OS there surely won't be any easy approach. I was looking for something outside that, it wouldn't be so hard to just ignore the ACL entries and have full power access to the disk. – Tom Wijsman Apr 24 '12 at 11:12
You'd have to do it external to the OS, so I imagine even the installation medium may prevent you. Is it because the files are ATTRIB +S that you're being prevented? If so, there may not be an easy way around this using built-in utilities. – user3463 Apr 24 '12 at 17:31
