Still, I am against compression. But for another reason. I wouldn't want to rely on compressed data, since it has a worse read/write error tolerance compared to uncompressed data. This is because the Shannon entropy will be raised significantly by compressing data. Which makes a possible loss of information all the worse. For example if in your uncompressed video file a bit is flipped it may produce an ugly block when playing it back. Using compression such a flipped bit can make the whole video file useless (not decompressable anymore or very alterated when uncompressed).

This is pretty much sums up what I was talking about with NTFS compression: Quote:
Another thing to be careful with NTFS compression is that files will fragment more quickly, which can be the cause of slow performance. It's best to defragment the whole hard drive every week to avoid that.

LZ77 is very fast when decompressing. I wrote an LZ77 decompressor with decrypter for the archive files of a certain 3D game in C# and never actually had a performance issue with reading data (hdd would be the major bottleneck). But writing compressed is definitly slower (depending on compression level) and more of a performance issue. Now when a system boots up, all the system files will be loaded into RAM. Reading is not the real performance issue even for system files. But there is the local disk cache (pagefile) that is heavily used in Windows (even when it technically isn't necessary because of a large RAM - especially in Vista). This one file will be written a lot and hence is a performance killer. Similar files are the working copies for the registry and other such working copies that are persistent for only one user session. edit: Actually the pagefile could be moved to an uncompressed partition (if available) to speed things up a little bit.

I also found out that the next version of Mac OS X, Snow Leopard also have support for HFS+ Compression, which works pretty much the same as NTFS compression since it's transparent and the files will be still readable with older versions of Mac OS X, but it's only applies to read only files, unlike NTFS Compression which you can still modify the file, which won't be a big help for sparse files

To Furuno: I don't know if these are the screenshots you want but yeah x.x; here they are:
Before Spoiler:
After - Estimating time at about....10 mins later Spoiler:
And errrmmm.... I don't know if its right to upload this or its relevant but I thought you guys might need this screenshot: Spoiler:
The 'Compress Old Files' actually grow alot by the duration of the space intake x__x So yeah...thought it'll be relevant to show this |

My first thought is : check inside your computer especially around the drive bay for carnivorous micro bunnies, it seems kinda populer recently. Of course, I'm joking, but wow the space really decreasing for some 200 MB... What are you doing during that 10 minutes?
Well, judging from the amount of space that you recover from disk cleanup, I don't think disk cleanup can help you much in there... 45 MB... Indeed, just as Dreamtale said, it might be easier to buy new HDD (or the whole PC if you want to), because I'm started thinking that there's something wrong with your HDD. Oh, and you might want to do some check disk and/or try reinstalling first...

Also, compressing 45 MB is negligible and was the first screenshot from when you started your computer? |

Usually when I restart my comp as an experimenting method, it'll at leas decrease down to 30-40MB >>; But I guess I've stated before, sometimes I have to shut down my comp for 2 days just to get it down to at least 4GB at max And thanks Dreamtale xD Thats what I'm actually saving money for I've been trying to call my family technician but he's been busy all the time so >>; may just find another technician close to where I live... And not much really, Furuno....Errr...had msn with 4 windows--- Actually, if Firefox had alot of tabs, would it also heave and giving effect to the space eating carnival? |

I know another possible cause... the paging file... Usually, it's best just to manually set the paging size. It should at least be double the memory. (meaning if you have 1 GB of RAM, you should set the paging file to 2 GB. If you have more than 4 GB, a paging file will become unnecessary since you won't likely use all the RAM possible.
Also, you can also move the paging file to another drive, but that drive must be plugged in when you boot into your computer. The benefit of having the paging file on another drive is that it will take less load on the main HD, which can make your system faster.

Oh yeah it's only 20 MB, I was kinda sleepy last time I post
Well, yeah judging from the amount of reduction and what are you doing, I agree with chikorita157. It's probably the paging file trying to increase it size and the browser cache. You can also try to disable (or at least reduce) the browser cache in Firefox by going to Edit > Preference > Advanced > Network. Altough usually Firefox won't use a lot of amount of cache, and disabling cache might result in slower browsing experience, especially if your internet connection is not that good.

Well I don't think I'm gonna mess with the cache since I don't feel its all that necessary...
but I'm gonna try exploring C drive and delete some temporary files or something. Mean time x__x Im gonna try calling my family technician and really persist for him to come over O-o and maybe ask for a new HDD...I guess. But I just wanna say thank you all for helping me ;__; even your time replying to this thread means something to me xD Even though there's really not much I can do aside from just buying a new HDD or calling a technician to settle all of it. Especially to Furuno, Chikorita, Dreamtale and Jinto xD Cause I really gain alot of unexpected knowledge about IT from you guys and I really appreciate it *hugs all* I'll keep you guys up to date with any changes about my comp~ x3 |
