7-Zip Portable v9.20 Rev 3

SYSTEM on 27 Oct 2013

7-Zip is an archive manager supporting the creation and viewing of a wide variety of different formats. Includes folder favorites, optional 2-pane view, available AES encryption, checksum calculator, file split/combine capability, and more.

7-zip is the official file archiver for the open, high-compression "7z" format that achieves higher compression than many others via LZMA algorithms. In addition, 7-Zip supports the creation of ZIP, GZIP, BZIP2, TAR, and XZ files, as well as the extraction of RAR, CAB, ISO, ARJ, LZH, CHM, Z, CPIO, RPM, DEB, NSIS, NTFS, FAT, VHD, MBR, APM, SquashFS, CramFS and MSLZ files.

7-Zip Portable is a wrapper from PortableApps.com and supports 32 or 64-bit automatically. Alternatively, X-7zip is also available.

@webfork:
Ruby had already told me that I am incorrect, 7-Zip Portable writes its vital settings to the Windows registry.
Now, either you must prove that you are correct or Ruby must prove himself or herself correct. I don't care who is correct. Just tell the entire truth about how 7-Zip Portable write its vital settings.

@Mixture
Your initial post indicated using 7-Zip without the PAF format in which case settings are stored in the registry.

7-Zip Portable will backup any local 7-Zip registry settings which allows the portable 7-Zip (PAF) to use that registry key to R/W settings to and when finished will restore the local 7-Zip registry key backup

Magibon on 2013-10-27 13:39

Ruby is correct.. the PortableApps.com launcher backsup the local registry, imports any user settings, then restores the registry after usage.

Which is why PAF Launchers rock.

FYI: don't confuse 7zip.com for 7-zip.org.. i did it by accident via Google.

PortableApps.com AppCompactor v3.2.0 Updated

Checker on 30 Aug 2014
  • 787KB (uncompressed)
  • Suggested by Checker

PortableApps.com AppCompactor allows you to compress whole directories including applications, file libraries, and zip files. The program is a powerful compression tool that unites 7-zip and UPX inside a user-friendly wizard. For applications, this saves disk space and increases performance when running from a slow media (like flash drives). For archives, this will recompress DLL, EXE, ZIP, JAR, IRC, PYD and BIN files to their maximum compression settings, as well as an option to decompress an app's binary files that were previously compressed with UPX.

All files are tested using UPX's test feature after compressing. Files smaller than 4K are automatically skipped as compressing will not save space on the drive. The standard Microsoft Visual C runtimes are skipped to prevent antivirus false-positives. Advanced configuration can be done with apps in PortableApps.com Format.

Note: As UPX will alter the EXEs and DLLs (reversible using the Decompress option in the AppCompactor) and some apps may have issues with Zip or Jar files compressed further, users should backup software and test it after processing.

tommyD: Disadvantages are that it breaks some programs, and it may be slightly more CPU-intensive to decompress libraries and executables on the fly.

I agree with wf; where is operaportable?

Universal Extractor v1.6.1 Updated

Checker on 29 Aug 2014

Universal Extractor allows you to extract files from many types of archive files, including ZIP, ARJ, LZH, as well as MSI and EXE files created using various installer packages such as Wise and Inno Setup etc. Useful for testing apps for portability because you can extract files directly from installer packages without having to go through the installation process.

Alternatively, an unofficial version with the latest-and-greatest internals is available (on Lupo's PenSuite site).

Commercial use note: There are restrictions on the included files UHARC02.EXE and UHARC04.EXE. These files can be deleted without dramatic impact on the software and will only disable extraction of a small number of file types. See website for more information.

It's a bit OTT calling this an universal extractor, as many EXE files I try to extract with it, leads to error messages that the so-scalled universal extractor can't extract them.

Why all the fuss over RAR? The biggest problem is getting RAR to ZIP so it's compatible to more people in the world, not less. 1980 called, they want their compressor back.

Midas on 2014-05-25 19:18

The changelog posted is for ArcConvert v0.66, plus there now seems to be a 64 bits version linked at the bottom of the Sourceforge page ("Update for 64bit OS").

Note also that although WinRAR gives you a 30 day trial, as the meme goes, it will never end...

(e.g., http://www.quickmeme.com/meme/3q6w51)

webfork on 2014-05-30 23:25

DavidRoper: even among very technical people, I can't seem to get anyone to use anything but ZIP. The dream of getting people to use one of a number of radically better compression formats has been going on for over a decade now and at this stage just seems like a lost cause.
