Hide existence of the encrypted file to a disk inspection

Truecrypt lets you change the extension, so you can disguise the file as another and, if it is opened in the other program it appears as just a corrupted file. Nice idea EXCEPT that methods exist to detect that it IS a Truecrypt file (google for more info) and for some uses this is a very big deal. The reason to use THIS program WOULD be if this is not detectable. It is detectable now but there ARE ways to make it NOT detectable. If you want to compete, this is one way to do it because, otherwise, this is not a competitive program to the freeware out there.
