as the topic said.. I got problem with 2 files. Since my Hd is 10GB I usually delete or store (somewhere) the files that I dont need at the moment. But I noticed that I got 2 files..
pagefile.sys (750mb)
and
hiberfil.sys (540mb)
cant I make them smaller? 
or possibly get rid of them without screwing anything up in the system? someone must have had the same problem before.. help
Both of them are temporary files. A page file is a file thats used when you dont have egnouf ram to run something. Thats why programs run realy slow on computers with less ram rather then not running at all, cause instead of using all speed racer RAM, its forced to use ghetto gtang hard drive space. You can make the page file smaller by going into system prefs someplace (dont feel like looking for it) but i woulnt recomend. The hybrination file is similar (i dont realy know much about it). Basicaly its used when your computer goes into hybrination mode it stores everything thats in the ram (cause the ram is 'shut down'', and when you decide to take it out of hybrination mode, it pumps all that data back into the RAM.
So no, you cant realy delete them a) windows probaly wont let you, or realy screw up if you do 
theyl be there when you restart anyhow.
heres the page file system propertys, advanced tab, preformance boxlike thingmaboby, settings button in box thingamaboby, new window opens, advanced tab, virtual memory box thingamaboby, change button, and change them in the new dialog.
From your control panel, select Power Options, find the Hibernate tab, de-select 'Enable hibernation'.
This will stop your computer from hibernating and thereby automatically delete the hiberfil.sys file, reagaining all that space 
For some reason I thought that deleting them would be a bad idea.. thank you for confirming it.
ps. what does hiberation in windows actually do?
it just saves the content in memory onto the hard drive so your computer can enter a restful state.
