Customer Reviews

Works perfectly

I had to read a few things on the developer's website to get a few things working:
- The Open In feature working (TrueCrypt volumes must have a .tc file extension)
- Had to make a new container using FAT (NTFS isn't currently supported)
- My main text file wouldn't open (saved as .docx and opens fine now)

All that being said, I'm thrilled to finally be able to carry my encrypted containers with me - don't have to go to my main PC to look up a vital record now.

Great job and keep up the great work! Looking forward to being able to search and edit files in a later version.


It took me a bit to figure out how to access my veracrypt container in Dropbox. I had to look on the developer's website for the directions but one I got it setup I can access my encrypted online documents from my iPhone flawlessly! Great software! Thanks!

Great software but has not been updated in a year

Works very well with TrueCrypt containers.
Decent Dropbox integration - if your container file is in Dropbox, you can open it in Disk Decipher.

The software has not been updated in a year. The developer may have lost interest.
Basic file browser features are not supported. If you have a directory with many files, or a large subdirectory structure, you cannot search for files.
You can’t sort by date.
