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.

Ruby on 2013-02-13 23:27

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 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 for i did it by accident via Google.

FileOptimizer v7.50.1247 Updated

Checker on 25 Apr 2015
  • 95MB (uncompressed)
  • Released on 24 Apr 2015
  • Suggested by I am Baas

FileOptimizer is a file compression tool used to reduce a variety of file types without changing the quality, also known as "lossless" compression. This is done via wide variety of optimization tools and recompression tools and techniques. Original files are sent to the recycle bin for restoration in the event the uncompressed version is preferred. A long list of supported formats include audio/video (MP3, OGG, M4A), image (GIF, JPEG, PNG), office formats (DOCX, XLSX, ODT, PDF), and system files (DLL, EXE).

Supports drag-and-drop of files into the window or onto the program icon.

A 64-bit version is available (within the folder) and the author reports the program is functional in WINE.

System Requirements: Win2K / WinXP / Vista / Win7 / Win8 / Wine
Writes settings to: Application folder
Stealth: ? Yes
License: GNU Lesser General Public License (LGPL)
How to extract: Download the ZIP package and extract to a folder of your choice. Launch FileOptimizer32.exe (for 32-bit OS) or FileOptimizer64.exe (for 64-bit OS).

Optionally, to save space:
  • 32-bit systems: delete FileOptimizer64.exe and the \Plugins64 folder
  • 64-bit systems: delete FileOptimizer32.exe and the \Plugins32 folder

  • Updated ImageMagick to 6.9.12.
  • Some minor optimizations and code cleanup.

Universal Extractor v1.6.1

webfork on 8 Nov 2014

Universal Extractor allows you to extract files from a wide variety of archive files, including ZIP, ARJ, LZH, as well as MSI and EXE files created using various installer packages (such as Nullsoft, Wise, 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. Note that the original developer no longer updates the program so some manual updates may be required.

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

Commercial use note: license restrictions are present on included files UHARC02.EXE and UHARC04.EXE, but can be deleted without dramatic impact on the software. See website for more information.

Writes settings to: Application folder

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.

Numanoid on 2014-11-01 14:32

This programme is in fact pretty much useless, there hasn't been one exe I have tried to extract over the last couple of months, where the so-called Universal Extractor has failed me :-(
