You will most likely only encounter an MBLOCK file if you use the mBlock application to create and save programs. mBlock is a STEAM education tool that implements Science, Technology, Engineering, Arts, and Mathematics (STEAM) principles to help kids learn programming basics.

You can only create MBLOCK files with mBlock. When you save the program for the first time by selecting File → Save to your computer, mBlock creates the MBLOCK file to store the contents of the program. You can then share your program project with other users via email or cloud storage service. You can also publish programs to the mBlock website directly from the desktop program to share them with other users.

NOTE: An MBLOCK file is similar to a Scratch 3.0 .SB3 project file. It is simply a .ZIP archive that stores contents such as sprites, scripts, .JSON metadata files, and .WAV sound files.

How to open an MBLOCK file

You can open an MBLOCK file with mBlock in Windows or macOS by selecting File → Open from your computer. You can also open an MBLOCK file stored on the mBlock site by selecting File → Open.

In the website version of mBlock you can open an MBLOCK file by selecting File → Open from your computer, then choosing the MBLOCK file you want to upload.

Since MBLOCK files are compressed with Zip compression you can extract the contents of the files with Zip utilities, such as Corel WinZip, 7-Zip, or Apple Archive Utility. Change the .mblock file extension to .zip and unzip the file with the Zip utility.
