U3 support was decommissioned. This page is temporarily kept for reference only.

WinSCP was available also as U3 package. U3 was smart USB drive that allowed installing applications on it.

WinSCP U3 package is WinSCP preconfigured for portable usage in format required by U3.

Content and features of the WinSCP U3 package:

• WinSCP software.
• Configuration (including stored sessions) is stored into an INI file on the U3 drive.
• Ensures that no traces of WinSCP (configuration, temporary files, etc.) remains on a host computer, once the U3 drive is removed.

The WinSCP U3 package has some limitations comparing to full product.

• It misses drag&drop shell extension.
• It is not possible to install and select another language than English. See below for manual installation.

You cannot download WinSCP U3 Package anymore.

WinSCP U3 package is preconfigured to use PuTTY for U3 for Open in PuTTY command. It has PuTTY path preconfigured to temporary folder, where U3 drive extracts the PuTTY for U3. As the extraction happens on the first execution, the Open in PuTTY command would not work until you execute PuTTY at least once manually from U3 Launchpad.

WinSCP U3 package does not include localizations by itself yet. They can be included manually as follows:

• Install WinSCP on your U3 drive.
• Locate WinSCP U3 package winscpXXX.u3p on your U3 drive. It is in directory \System\Apps\48b341d1-d411-4b5a-a82c-f3b5d65602fc. Note that \System directory is hidden.
• U3P format is ZIP file with special structure.
• Extract contents of the U3P file to temporary directory of your choice (you may need to rename the U3P file to .zip before).
• Store your translation file to subfolder Host.
• Archive the contents of temporary directory (including the translation) back into winscpXXX.u3p.
• Store the U3P file back to its original location on your U3 drive.
• Eject U3 drive.
• Insert U3 drive back and execute WinSCP.
• Switch to your language.
