This MTA module is about total filesystem access to your MTA server. You can find it's documentation here. It supports the Windows and Linux operating systems, each with different and specialized details (path handling, OS calls, etc). Contains many neat features such as memory-mapped files, stream copy helpers, direct binary-encoded writing and reading API, etc. The module has got a very long history (used in Scene2Res, Magic.TXD). It is very strongly unit tested. If you like this module then you can use it's C++ API for even greater freedom.
