A B64 file contains data encoded using Base64 encoding. This encoding converts digital data into text format for more reliable transmission over media like email. The B64 format enables sending attachments securely. It uses a 64 character set consisting of letters, digits and symbols like + and /.
B64 belongs to the compressed files category. Users can manage B64 files with WinZip software, although other programs support it too. B64 files can appear on any platform, but full support varies. If your system does not open a B64 file, install a program supporting that format. Right-click the file, choose “Open with” and select the program. Check “Always use” to set as default.
For Mac users: Double-click a B64 file icon to open it with associated application. If no program is associated, install and set default application. Online converters like Convert.Guru also securely convert B64 files to other formats.
The main issue is incorrect program associations for B64 files. They then open in unusual apps or have no assigned program. To resolve, double-click the B64 file to open with correct application if available. Otherwise, install software like StuffIt Deluxe supporting B64 files. Set that as default program to open B64 files.
