How do I synchronize my documents/files between my home and office computers through my removable USB flash/hard drive?

For this you need to setup mirror for the same source folder on both your office and home computers to a single folder on your USB drive. Now enable the following options for the mirror folder on both computers.

• Synchronize on startup or when connected
• Mirror under current logged on user account
• Compare file size and last modified time stamp
• Bi-directional synchronization
• Copy file differentially with block size (enable this if you have relatively large sized files and only a small section of them are modified normally)
