TruPax offering you a convenient way to transfer arbitrary numbers of files and directories into a new volume file. The size of the final container will be exactly of the space needed. This os done fast and straight, by creating the file system structures in the encrypted container on-the-fly - no second pass needed.

In other words: you can take a bunch of files and create a .tc file out of them right away.

TruPax Features:
1. creates file containers in the open UDF format, mountable on many modern operating systems.
2. created containers are writable on the more recent systems (Windows 7, OSX, Linux).
3. runs on any operating system where the Java 6 runtime is available.
4. is a completely new implemention of the TrueCrypt encryption technology.
5. uses all processor cores to do its job as fast as possible.
6. writes container files in just one pass. No seeking.
7. is free to use. No charges. No spyware either.
8. source code is available for review. No hiding.

TruPax has a pretty straightforward user interface: add files and folders you want to put in the new volume, then select the volume file and finally enter a password.

TruPax on the command line works similar to file tools like zip or tar: declare a target file and pass the files and folders you want to be processed into it. Thus the general way to call TruPax is:
trupax tc-container-file folder file (more files and folders...)
