What is a QBL file?
A file with .qbl extension is a QuickBooks license file that contains licensing information for the user’s purchased copy. It is usually stored in local system with the name
license.qbl after QuickBooks is installed and user enters the licensing information in the software when software is run for the first time. QBL was the earlier file format used for storing QuickBooks licensing information. This has now been replaced by the QuickBooks
qbregisteration.dat file and is populated with information from user’s confirmation email, purchased DVD, or through other buying means. QBL files can be opened in any text editors such as Windows Notepad, Apple TextEdit, Notepad++, Github Atom editor, and many more.
