What is a .B2A file?
A .B2A file is a special kind of text file. It's made by changing a file that's usually not text (like a picture or a program) into text using a method called btoa, which stands for "Binary to ASCII." This is useful because sometimes, when you want to send files over the internet or through other systems that only let you send text, you can't send these non-text files directly. By turning them into a .B2A file, which is text, you can send them over these text-only systems.
The way it works is a bit like translating a language. Imagine you have a message in French that you want to share with someone who only understands English. You would translate your French message into English. The btoa method does something similar by "translating" binary files (which computers understand) into ASCII text files (which can be sent over text-based systems).
To open a .B2A file, you can use several programs. One simple tool is called "atob," which does the reverse of btoa - it takes the text file and turns it back into its original form. There are also more complex programs like Ascii85 Decoder and Smith Micro StuffIt Deluxe (available for both Windows and Mac), which can handle these files too.
The btoa method is known for making files a bit smaller than similar methods like Base64 and Uuencode. This can be handy because it means the files take up less space and can be sent more quickly. Often, you can tell a file has been encoded with btoa because it starts with the text "xbtoa Begin," which is like a signal that the file was translated using the btoa method.
Verification
Our goal is to help people find the most up-to-date information about file extensions for Windows, Mac, Linux, Android and iOS. We researched over 10,000 file extensions and their respective programs that open those files.
