7-Zip Portable v16.04

webfork on 26 Jan 2017
  • 6MB (uncompressed)
  • Released on 7 Oct 2016
  • Suggested by Andrew Lee

7-Zip is an archive manager that can view and create a wide variety of formats. The program includes folder favorites, optional two-pane view, checksum calculator, file split/combine capability, and more. Individual archives can be created with high speed or high compression settings, update options (including update, add/replace, synchronize), split volumes, and more. Archives can be secured with standard zip or more secure AES encryption.

Although the official archiver for the open, high-compression "7z" format, the program also supports the creation of multiple formats including ZIP, XZ, BZIP2, GZIP, TAR, and WIM. It will extract a long list of other formats, among them RAR, CAB, ISO, ARJ, RPM, VHD, VMDK, etc.

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

Archive encryption in 7z has been broken since 2009, maybe even longer, its been reported time and time again but the dev stance about this has been that it's not a priority.

All that is required is a plain .txt file to break the view protection of a passworded 7z file. If you need simple single file encryption I would suggest AxCrypt for that.

@Special:
What? What are you talking about? What broken, what reported, what plain .txt file? Can you elaborate?

Special on 2017-01-24 02:20

Normally you would need to know the password to access a passworded 7z archive or to even look inside one, but by using the 7z file manager you can still add stuff into a passworded archive by just dragging & dropping stuff onto it, for example a blank .txt file, that is the first part, then with the use of a simple Hex editor (HxD) you can break the password "lock" if you know what to look for. What I'm saying is, use 7-Zip for your compression needs, but for encrypting sensitive stuff you plan on uploading onto the web, look elsewhere.

FileOptimizer v10.10 Updated

billon on 28 Jul 2017
  • 194MB (uncompressed)
  • Released on 28 Jul 2017
  • Suggested by I am Baas

FileOptimizer is a broad format file compression tool used to reduce file size without changing the quality, known as "lossless." This is done via wide variety of optimization 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. Note that by default the program removes metadata for many file types. This information reduces overall file size and protects privacy but is important to some users (e.g. photographers) and file search tools.

A 64-bit version is available within the folder, the author reports the program is functional in WINE, and can be used on the command line.

- Improved GUI draw performance.
- Improved pingo lossy optimizations for JPEG and PNG.
- Improved gifsicle and gifsicle-lossy performance by allowing using more memory, and using several threads.

There are a lot of great ways to compress files and folders quickly and easily, but most people are only familiar with ZIP. PeaExtractor's broad support means that it frees us up to send the latest and best compression formats without wondering if the recipient will have difficulty opening it.

Ideal for upgrading compression (e.g. ZIP -> 7ZIP) or to change an archive to a format supported by your preferred program (e.g. RAR -> CAB).

Supports a long list formats are supported including ZIP, 7-ZIP, RAR, TGZ, as well as ~60 other lesser-known formats. The program can save to ZIP, 7-ZIP, CAB, LHA, TAR, TGZ, BZ2, YZ1, BGA, RAR, ACE, NOA32, PAQAR, UHARC, YZ2, DZ, HA, XZ, and FreeArc

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...

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.
