When launching a U3-compliant application from a U3 flash drive, the application loads the system files that it needs.

When disconnecting the U3 flash drive from the computer, the application remove the information from the computer. All settings and customizations remain with the application on the U3 flash drive.

Software vendors who planned to create U3-compliant applications include ICQ, Skype, Trend Micro, Zone Labs and Ulead Systems. Other than SanDisk, other USB flash drive manufacturers including Kingston, Memorex and Verbatim also showed interest in the U3 platform.

However, the U3 technology faced various problems including incompatibility issues with some embedded system and slowness issues with certain Windows drivers. In 2009, SanDisk began to phase out support for the U3 technology and U3 applications were no longer available for download.
