Carry It Easy U3 (officially Carry it Easy™ – U3 Edition) is a discontinued, highly popular legacy USB utility software developed by CoSoSys. It was specifically designed for U3 Smart Drives—a generation of intelligent USB flash drives created by SanDisk and M-Systems in the mid-2000s.
The tool acted as a portable desktop environment, allowing users to carry data, settings, and standalone applications on their flash drive to use securely on any public or guest computer. Key Features
File and Folder Synchronization: It allowed users to sync documents and personal folders seamlessly between multiple host computers (like a work PC and a home PC) and the USB drive.
Portable Email (Outlook Sync): Users could carry their Microsoft Outlook or Outlook Express emails, address books, and local settings directly on the drive, letting them read and write emails from any guest PC without local configuration.
No-Trace Browsing: It synchronized Internet Explorer favorites and allowed web browsing where cookies, history, and internet cache were saved directly to the flash drive instead of the host computer, leaving no trail behind.
128-bit AES Encryption: It allowed users to password-protect a dedicated “Personal Data” folder on the drive using secure encryption.
Lost & Found Feature: If the USB stick was misplaced, the software allowed an honest finder to see the owner’s contact details on the unencrypted partition without giving them access to the password-protected files. How the U3 Platform Worked
Traditional USB drives of that era only stored raw data. U3 Smart Drives utilized a unique hardware controller that split the drive into two partitions: Carry it Easy +Plus 3.0.1.0 Free Download
