Compressing program

[arcadeplayer987]

Does anyone know any good compressing program??

[xris]

It would help if we knew what sort of files you wanted to compress since this will effect the answer.

try 7-zip its a good program for compressing and its free

Well...in the mainstream there are WinZIP, WinRAR, 7Zip, and Stuffit. I'll break these down for you:

WinZIP (.zip) is probably the most popular program and .zip the most popular compression scheme. Windows has natively supported its .zip format since XP.

WinRAR (.rar) is WinZIP's close competitor, and is marginally better than the .zip compression scheme. If I remember correctly, WinZIP holds to .zip and its derivatives along and doesn't support .rar files. WinRAR as a program supports ZIP files along with a large growing list of others.

7Zip (.7z) performs much better when it comes to compression, but it's not very widespread as a file. WinRAR can read 7Zip files, but so far cannot create them - only the original 7Zip program can.

Stuffit is a far less known utility that lives mostly in the Apple family, and there isn't much use for it outside of that.

There really isn't much else if you want anyone other than yourself to use the files that you're compressing - some compression schemes require one single special program that must be installed. I use WinRAR, by the way, just because it's very versatile.

You also need to be aware that you won't get good compression using any of these programs if the files you are trying to compress are already compressed.

Most Video and music files won't get compressed much further (we're talking maybe 1-2%) because they're already compressed files.

Just saying that since I've seen people ask here about compression before thinking that winrar or something is going to cut their anime filesize in half or something. It doesn't work like that.

I was using WinRar to compress a movie iso image 4.5Gb but no luck, the result was only a few mb less

ISO is one of those files that jpwong mentioned: they can't get any smaller, really. Text files (.txt, .doc, .rtf, .htm) and picture files (.jpg, .gif, etc.) are the most compressible.

You can always split the files if you just want to burn it off your HD.

If you're talking about a DVD movie ISO image, then there are actually tons of ways to make it smaller, as long as you don't mind messing with the DVD structure.

To save a few MB (and make it fit on a single layer DVD+R) you can take out things like logo's and other extras, or even taking out whole audio tracks (like commentary etc) and the menu (if you don't care about it).

Or if you really need to shrink the size down there are applications that can re-encode the video of a DVD movie without changing the structure using DVD Shrink (which isn't the best quality solution, but the easiest).

If the DVD iso is really huge (8 GB) and you don't want to mess with the video quality, you can even split a DVD movie while keeping the menu's intact with DVDFab (although these days DL discs aren't so expensive anymore).

It's been a while since I tried anything like that though, so if you need help on doing this, try www.videohelp.com or www.doom9.org

If you just want to store the dvd data, you can do that in WinRar and 7Zip. "Store" the image in an archive (no compression) and select the option to split into whatever-sized chunks you need; 7Zip gives you options for floppy, CD (650M & 700M) and DVD (4480M). Of course, now it's unplayable/inaccessible until you copy it back onto HD and unarchive.

If you're talking about splitting a movie into 2 playable/viewable video files, check the videohelp.com guides.
