Wow, UCCX 5.0, that's an oldie. Enjoying your yellow and blue web pages? Also, if you're planning to upgrade to 8.0 or higher, note that you can no longer use the local file system or database. Begin the process now to clean that up and fix your process/logic so you're only using the repositories and external data sources. This will make your transition to the Linux appliance much easier.
My opinions...
So, we're talking about Windows Server 2003 then. You can pretty much delete anything you want, that is temporary in nature, without affecting call processing. However, you may find that your repositories are actually taking up a lot of space. Delete old scripts, prompts, and documents that are no longer in use. There's not really an easy way to do this, so just start looking at your applications and scripts to see what's being used.
You can check the log files folders and delete logs. I would stop the cluster manager first, then delete logs, then start it again. Double check your log settings to make sure it's not keeping too many logs around.
Also check your BARS backups, as someone may be backing up locally and leaving the backups laying around.
If you were feeling up to it, you could take a backup, rebuild the server from scratch, then restore from backup and that would only use the necessary files required for operation.
As for the page file, you really cannot do much here. You can adjust it's size, but I've never had to do that or heard of anyone doing that on a UCCX instance. The page file, if you didn't know, is the swap space for the OS to put things which are in memory right now, but not being used at the moment. If you decrease its size, you risk dropping the server performance. If you increase it, you just worsen the disk space issue.
I hope that helped.
