Toucan is a simple tool with which you can synchronize contents between your hard drive and a portable memory device. Well, in fact you can use it with any other drive –even mapped network drives, as long as the program has support for it.

Its tabbed interface makes it very easy to use. Besides synchronizing with four different methods, the program also makes compressed backup copies (even incremental ones) and allows you to encrypt and decrypt data. These three functions are pretty straightforward, but I couldn't figure out the utility of the fourth tab, "Portable Variables". Only after browsing the program's directory I could find some help inside Apptoucanhelp.
