ThanksAutoRun Configuration (autorun.inf)
In this section, you can configure the 'traveler disk' to automatically start TrueCrypt or mount a specified TrueCrypt volume when the 'traveler disk' is inserted. This is accomplished by creating a special script file called 'autorun.inf' on the traveler disk. This file is automatically executed by the operating system each time the 'traveler disk' is inserted.
Note, however, that this feature only works for removable storage devices such as CD/DVD (Windows XP SP2, Windows Vista, or a later version of Windows is required for this feature to work on USB memory sticks) and only when it is enabled in the operating system. Depending on the operating system configuration, these auto-run and auto-mount features may work only when the traveler disk files are created on a non-writable CD/DVD-like medium (which is not a bug in TrueCrypt but a limitation of Windows).
