How to open BLL files

Did your computer fail to open a BLL file? We explain what BLL files are and recommend software that we know can open or convert your files.

What is a BLL file?

BLL files are Borland Language Library files, which you can read more about below.

The BLL file extension indicates to your device which app can open the file. However, different apps may use the same file extension for different types of data. So a BLL opener may not be able to open all kinds of BLL files. In this case, though, we only know of one specific use.
