What is an .B2A file?

.B2A is Btoa Encoded File

ASCII text file that has been created from a binary file using the btoa (Binary to ASCII) algorithm; used for sending binary files over protocols that only support text-based data transfers.

The btoa algorithm is similar to the Base64 and Uuencode algorithms, but creates slightly smaller file sizes. Btoa-encoded files often start with the text "xbtoa Begin."
