7-ZipPortable is a portable version of the popular 7-Zip application. 7-Zip is a file archiver with a high compression ratio.

Support

To recompile this PAF you must use my version of the PortableApps.com Launcher.

Download

All downloads available in the Releases section. This portable application was packaged using a modified version of the PortableApps.com Launcher.

Features

  • Runs the full 7-Zip file/archive manager.
  • Completely portable - runs off a USB, cloud drive (DropBox, iCloud drive, OneDrive, etc) or hard drive.
  • No need for any external software - simply download extract and run!
  • Packaged in PortableApps.com format for easy integration.
  • Associations are supported and easily customizable.

To add your own file associations, open the 7-ZipPortable.ini file. Under [Associations] add any extension you wish to support. For example:

[Associations]
1=7z
2=001
3=rar
4=zip

For a list of all supported filetypes, open AppInfo.ini and review the [Associations]Filetypes key.

Note:

  • Adding a lot of extensions can and will effect launch time.
  • Windows XP tends to cache icon resources which are inevitably visible even after exiting 7-Zip.
  • Windows 8 can be problematic and may require unlocking for some filetypes—i.e. when double-clicking on a supported file format and Windows asks you to select 7-Zip from a list. This is because Windows 8 has an implementation of a hash ID for associations.
  • Do not associate through 7-Zip! This will leave trash in the registry when you exit the program.
  • SendTo is also available for any filetypes that aren't associated but are supported for use with 7-Zip.
  • Added ability to use shell extension/context menu features. See user configuration file to enable. Do not enable this feature through 7-Zip!
  • The user configuration file includes the following optional settings:
[7-ZipPortable]
AdditionalParameters=
ShellExtension=true
RunLocally=false
USBDevice=false
Banner=false
  • AdditionalParameters: Pass additional command-line switches.
  • ShellExtension: (true, false, auto) Enable/disable Shell Extension/Context Menu features. Requires administrative rights.
  • RunLocally: (true/false) Application is copied to and executed from %TEMP% directory.
  • USBDevice: (true/false) Enable to prevent ejection/unplugging problems with removable devices. When ShellExtension is enabled, Windows Explorer tends to lock application's DLL(s). If enabled, PAF will ensure DLL(s) are unlocked.
  • Banner: (true/false) Enable/disable initialization banner.
  • More features soon to come!
