How to make files smaller?

Have you tried 7-zip?

It is free, and it is quite good (multi-thread capable apparently). The 7z format is suppossed to be better than Winrar and others for compression.
 
If it is an already compressed file like DIVX, MP3, JPEG then it will not compress much at all.

yep. especially when you get into lossy compressions. Those are literally compressed so much that data is getting discarded. Trying to do additional compression won't work.

Only exception I know of is the Solid Archive option in winrar. That looks for duplicate data across multiple files. If what you are trying to compress is a single file this won't help much. If you have a batch of mp3s, jpgs or whatnot that are individual files then solid archiving will help. It's slow as all get-out though.
 
A possibly relevant idea, and a question - why are there no multipass file compression programs? Or do I simply not know of them?
 
no its just a folder yeah its filled with movies and music but it doesnt effect quality iam just compressign the folder!

Compression the folder is the same ascompressing the files within the folder.

As has been stated previously; the compression of certain types of files does not be very effective.

 
You do know you can split RAR archives so they span multiple smaller files? This is helpful for backing up large files to CD/DVD.

Because they don't work. Try zipping up a zip file and see how much smaller it gets.

lol
anyway i have 33gb of music and like 32.9 gb free space 🙂

i bet if you go over your music, you can find enough duplicates to delete to make up the difference.

So here's a bad analogy. A song is like a baloon.

Losslessly compressing a song is like untying a baloon and letting the air out, you can reinflate it later if you want. Converting it to mp3 is like popping it, you lose bits and pieces and there's no hope of reinflating it.

Every "baloon" in your folder has already been either deflated or popped. When you try to compress the folder, that's the equivalent of putting all of your baloons in a bag. They're all in one container now, but it's not any smaller.
 
ugh im lost lol

Do I need to uninstall the existing winRAR before getting the 7-zip?

No, I don't think so. I've had it with WinZip and another program on the same machine.

That's not true multipass compression though, is it? Multipass compression, such as in PNGOut can reduce the filesize of a losslessly compressed PNG file, and it can do 10 or more passes, each pass reducing the filesize further. I imagine that it uses different compression routines with each pass, otherwise there'd be no point. A ZIP compression engine designed from the start to support true multipass compression could offer benefits.
