SB2 File - opening and understanding

Did your computer fail to open a SB2 file? We explain what they are used for and recommend software that we know can open or otherwise handle your .SB2 files.

What is a SB2 file?

The .sb2 file extension is used by the SerialBox serial number collection website. The SB2 files contain a collection of serial numbers that can be used to unlock proprietary software products. Users take the serial numbers contained in the files to unlock "pirated" copies of popular software applications. It is important to note that while the serial numbers located in the SB2 files will unlock popular software applications, using a serial number that you did not purchase to unlock software that you did not pay for is illegal in the United States.
