Support

To recompile this PAF you must use my variant of the PortableApps.com Launcher, Pac-Man.

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!

System Requirements

• Microsoft Windows XP or later.
