## need help with hard drive

Hi, so recently I bought an external hard drive and started transferring my data into that to get more space in my internal one. I then noticed that I've used up almost 50% of my c drive but I don't know what it's used for and don't see anything that would use up this much memory. Is there any way to find and tell me what these programs/files are so I can transfer/remove them? Thanks

Conventionally, drive space isn't referred to as 'memory' although it is abstractly similar, but of course, matter is abstractly similar to memory so we do make distinctions.

You will have to look through the folders on c: to see what is using the space. You'll probably find that most space goes to c:/pagefile.sys and your 'Program Files' and 'Windows' folders.
 The problem is I can't identify which ones i should look at

sry for double posting but I read online that deleting the files and emptying the recycling bin doesn't really help so what do I do to find the files I've already deleted as well as permanently wiping all the useless stuff out?

EDIT: So I clicked on properties to see how much space each file uses up and I only total up to 10gb of space on disk so i have no idea where 14 other gb of disk space went :(

Do you have hidden files and folders? You might have large files in various temp or browser-cache folders.
 Mentor Go to control panel ->administrative tools->computer management to find out what is going on with the drive.
 I'm starting to go back up to 72% now, I thought deleting would help increase performance and make my comp run more smoothly, but it seems it's getting even slower now, what's going on? EDIT: Another question, what is avanquest, i have it as a file and i don't know what it is. Can I delete it? oh and I downloaded treesize and did the wasted space tab and it showed me all these files and kb(assumed to be the wasted stuff) The thing is I have no idea what the files do. I mean there's something call pchealth and another one call inf and they each take up like 31,000kb of wasted space and then there's another file call $hf_mig$ and it takes like 27,000 kb of wasted space but i don't know what they are.... EDIT: I've been looking at computer management but I don't know what to do
 deleting files wont make it run any faster, you can try disk defrag
