I can do 7zip, tar, and zip...how do I get rar ?
You can't make a rar with 7zip, but you can extract them.

Too many bridges you can burn
Too many tables you can't turn
Don't wanna live my life in the real world
PeaZip Portable, that's how.
There's no place like 127.0.0.1
I don't think PeaZip can compress to rar, but it can open them
Peazip can only open it.
The only program that can make .rar files are:
Only closed source commercial (read: you pay for it) software can compress to RAR files. RAR is a closed source/proprietary software. There are some free decompression routines but none are open source, so none are included with open source compression/decompression software.
Sometimes, the impossible can become possible, if you're awesome!
To be fair it is possible to use both WinRAR and the command-line RAR program (for OS X, FreeBSD, Linux, OS/2, and DOS) forever to make and open archives without paying, although not all features will be available; I have found no need for whatever those features are though, the only effect I've seen of not paying is a nag screen whenever I look around inside an archive with WinRAR, which rarely happens because I prefer to use 7-Zip for that purpose.
Although the fact that WinRAR is still technically not even freeware means it will never be made available on PortableApps, Rarlab does make its own portable (non-PAF) version available: http://www.win-rar.com/unpluggedinfo.html
WinRAR or 7zip ?
and it's possible to make a backup for drivers ?with 7zip ?
I've learned that this life's not just a game,
Just a line between pleasures and the pain...
I like 7zip better. Its .7z compression is more superior than .rar. Also its free.
I don't know if 7Zip can be used to backup drivers (Though if they are contained within regular file types/structure I don't see why not) however just wanted to state 7zip and Peazip are both great products, Peazip is earlier in its development but shaping up well and 7Zip from my non techie point of view is the bomb:-D Seriously but in my experience WinRar has nothing over 7zip yet 7Zip is free, OSS and available in a portable version here at PortableApps.com. Also Peazip is available here too:-)
WinRar is faster, on some files much better (though overall compression is lower now), has a nice GUI, can modify own archives (solid 7zips are almost unmodifiable) and, IMO most importantly, allows to add error correction codes - with 7z a single bit error can kill all files in your very important backup.
That's definitely more than nothing.

Evidently you have more advanced knowledge of the software's then me. However I would think for the average user 7Zip will serve their purposes. Still from what you said it would seem WinRar has more features than I gave it credit for. Thanks for the info.
It is not only this, WinRAR has a killer feature "keep broken files" so you can only decompress and listen/view n'part (say folder name.01.rar) of a split archive (if you download audio loseless files or movies).
7-zip does not have the feature. 7-zip has a more aggressive compression algorithm, for what is worth. But speaking for myself, I use no compression or a light compression to save the processor unnecessary strain.
WinRAR is very old. Compression is of a lesser use with modern connection and high capacity HD of today. I would rather user a splitter - since it is faster in both way (split/merge), but you cannot split folders (since it is just a graphical DOS command) so these formats - winrar/7-zip - still have their use (e.g. when sharing an album: .flac, album scan.jpg, rip.log or movies)
If a newer 7-zip version has a similar feature "keep broken files", I will switch to an open source format.
I think, 7-zip compresses more well, than winrar. But in WinRAR there are more functions... But I use 7-zip.
But I use 7-zip & WinRar
