Recommended Posts

First update of this program for about a year and a half:

 

http://filehippo.com/download_7-zip/

 

Changelog:

 

- 7-Zip now can unpack Compound files (msi, doc, ...) and WIM archives.

Now it uses random initialization vectors.

 

- Speed optimizations.

of CPU threads in "Add to archive" dialog box.

- Default dictionary size was increased: Normal: 16 MB, Max: 32 MB.

- 7-Zip now can use multi-threading mode for compressing to .ZIP archives.

- 7-Zip now uses order list (list of extensions) for files sorting for compressing

to .7z archives. It can slightly increase compression ratio in some cases.

 

- 7-Zip now replaces incorrect characters in filenames during extracting.

- 7-Zip now restores modification time of folders during .7z archives extracting.

It's a good update. No need to uninstall a previous version either, just install over it and reboot if required.

I use 7-Zip very rarely, only for 7z archives. But maybe i will update, eventually.

I only switched to it sometime last year after WinRAR which I have licensed started acting really weird on my system, I don't know exactly what the problem was or if there was a conflict with another software or not however the problems were big enough for me to ditch it altogether. And it did take some serious getting used to 7-Zip after using WinRAR for so many years, that wasn't the easiest transition for me to deal with because I really liked WinRAR's SFX creation which could be used as an installer to create shortcuts, etc. Kind of makes me wish 7-Zip could utilize some Inno Setup scripting for it's SFX creation.

 

In any event I use 7-Zip each and every day, and like the fact that it utilizes multi-threading to speed things up. Also it's command line program is relatively easy for usage inside of batch files to backup all files in a specific backup folder I've created which makes life super simple and super easy when wanting to burn one backup archive that contains all backups onto a CD-RW. It's actually ages faster than any run-of-the-mill programs that are deemed "backup software."

 

I loved WinRAR before, however after using 7-Zip the past year without any significant bugs at this point I highly doubt that I'll ever go back to WinRAR, and have no desire to use any other archiving software.

My primary zipping program is UltimateZip. It handles RAR archives also.

 

Edit: Just noticed from UZ site, that 3.1 version got 7z and 7z sfx support. I got 3.0.3 version.

Time to update then I'd reckon. I'm always checking the 7-Zip SourceForge.net project page for updates which are released there before the main site shows them, and any new beta builds.

Andavari . . . I may be asking too much (or maybe I misunderstood what you said), but can you explain the procedure for backing up using 7-ZIP. Is there an Explorer feature, or how do you go about backing up and archiving multiple files? I'd like to backup a bunch of stuff on my hard drive to my external drive -- same stuff on a regular basis.

It's in the 7-Zip help file how to use it via a batch file, etc., to automatically backup a certain filetype, folder, etc.

 

Example:

 

"%ProgramFiles%\7-Zip\7z.exe" a "D:\My Backups.7z" "D:\My Backups"

Thanks, I'll check it out.
