In Windows, a truecrypt file (*.tc) looks like a normal data file. But in fact, it is encrypted container file and can be mounted as a drive where files can be accessed normally. And ss soon as drive is unmounted, then one cannot access the files any more.
A truecrypt file can be copied onto USB, making it great for protecting files while travelling.
