I just wanted to send a thank you to you guys for developing this software.My wife's school computer lost something in the windows files and started to fail to boot properly. She is in charge of some critical projects and had not backed up active files she was working on. I was able to use the OSX Bitlocker utility to unlock the drive (with help from the schools IT) and mount it to my Mac and viola we had her files back. This was so easy to use and it just worked wonderfully. Thank you guys all so much for the work you put into it.

My Win 8.1 box had a catastrophic failure. All of the external drives were encrypted with Bitlocker. I have no other Win boxes. I thought I was totally screwed. I also have a MacPro. While looking for quick solution to the problem I stumbled upon your product. I bought it and it works flawlessly. Thanks for such a fine product. After this, I will always look to you for solutions first. Thank you.

This would be good if it mounted like a normal drive once it was unlocked. Then it would be the perfect cross platform solution for mac and windows encrypted drives. If we have to export out the drive every time, this seems very counter intuitive. Especially for large files that need to save on the fly.
