Ive been running low on space lately and so I decided to start comrpessing some of my old stuff. I have tried RARing files, which has given minimal improvement.

Does anyone know of compression programs that can do lossless compression. I am willing to spend some money on it, so I do not mind if it is not freeware, aslong as the compression is good.

Maybe the hard drive is too small for all the data you want to keep on it? However, use good Temp Cleaner and Defrag the disk - if your system is in good shape as is - remove all except the newest Restore Point - alot of space can be recovered, Nebon.

Hi Connor

you ran out of HDD space? How large is that HDD you use in total or how large is the partition where Windows runs? I recommend 20 GB less to havae enough space for updates, mailfiles, settings and user profiles.

If you use MS IE, please check how much space is blocked at the following folders:

C:\Documents and Settings\<USER_PROFILE>\Local settings\Temp

C:\Documents and Settings\<USER_PROFILE>\Local settings\Temporary Internet Files

C:\Documents and Settings\<USER_PROFILE>\Local settings\History

It's a first address to delete useless entries here. Delete the content of directories via IE --> Extras --> Internet Options --> Temporary Internet Files
(delete Cookies, delete Files, empty history)

Another hint might be the folder "My Documents" with its subfolders "My pictures, My music, My videos" etc. Very often these directories are used as default setting when downloading or when saving files.

Hey Udo,

Thanks very much for the tips. I have a around 200gb of space on my computer. One 80gb and one 120gb harddrive. I have quite a few games and pictures and backups of things. The photos I have taken alone are quite substantial. A good few gig.

I use CCleaner and clean my temps, application data and old prefetch data out regulary. You are right about the my documents + subfolders. A few things I could delete there but nothing big unfortunately.

Thanks everyone.

Meheee again Connor

Hmm have you ever had a thought about swaping /move over that folder "My documents" to that HDD which has more free space than your boot drive?

Thanks Udo, that is a good idea and I will consider it.

Trying using 7zip this sometimes gives better results than rar files, although it does depend on what you are compressing. If it's AVI files then you won't see any improvement in size.

However if you have the time you may want to look at the following some of them can really give very good compression but it may take several hours to do.

KGB Archiver is the compression tool with an unbelievably high compression rate. Unfortunately, in spite of its powerful compression rate, it has high hardware requirements (I recommend processor with 1,5GHz clock and 256MB of RAM as an essential minimum). One of the advantages of KGB Archiver is also AES-256 encryption which is used to encrypt the archives. This is one of the strongest encryptions known for human.

Squeez

QUOTE

Squeez is a multifuntional program package to create and organize ARJ-, LHA and ZIP-archives. Because of its new compressing and decompressing modules it offers almost the same compression ratio but runs up to 100 percent faster than the original archivers. It lets you also create and handle multi-volume and self-extracting archives.

You may handle and create archives in two different ways:

One way way is to use Squeez itself. Squeez is a MDI-application. It opens per archive one window. You may compress or decompress archives via Drag&Drop, via Clipboard or in the traditional way using dialogs etc. You may copy files from one archive into another, even between different archive types.

The second way needs a special explanation. Squeez creates on your Desktop a virtual folder called "Squeez It". This folder appears also in the Explorer. Via Drag&Drop you can move archives into this special folder. Squeez creates in the root of all fixed disk drives a hidden folder called "Squeezed", in which you will find the archives. Because of the use of these special folders archives are treated like directories and are also available in the Explorer Directory Tree. You can create archives via Drag&Drop onto "Squeez It" or via "Send To". Uncompressing is possible from inside the Explorer, too.

Or alternatively why not invest in an external hdd.

Freecom 80GB External USB2.0 Hard Drive - Retail

I'm not saying buy from here or recommending this particular model but external hdd's are a great way to back up your important data and release space on a HDD.

I dont mind about the hardware spec required. Just one question, is KGB archiver lossless? Caus lossy would be bad.

I also already have a 300gb external HDD. That is where I move most of the files and do backups of all my computers in the house, but thanks again for the suggestion.

Thanks for the help guys :thumbup:

I've not used KGB, just heard about it on another forum and a comment said someone claimed they got 2007 Office beta down to 3mb!!!!! But that it took hours to compress, if the compression level is true.

Download page

From the download page I think V1 is the stable release and you probably shouldn't have any issues and loss of data, but I would suggest trying the software on some test data first to see what happens. If you have the room compress the data and then try extracting it and then validating it.

Just had a quick play with KGB and it doesn't appear to be much better than 7zip compression wise, just a lot lot slower at compressing.

Thats a shame. But its something I suppose. Thanks for all your help Stidyup.
