What is a QBK file?

QBK file is a backup file for Q08 and Q09 files. QBK file contains information regarding tax returns. QBK, Q08, and Q09 files are used by QuickTax software (and since 2008, by TurboTax), a program used for tax settlement procedures compatible with Canadian tax laws.

QBK, Q08, and Q09 hold identical contents and differ only in the file extension type. QBK backup copy file is generated immediately after the main file is saved. In order to recover the main file form backup copy, user needs only to change QBK file’s extension into Q08 or Q09.

How to open QBK files

If you cannot open the QBK file on your computer - there may be several reasons. The first and most important reason (the most common) is the lack of a suitable software that supports QBK among those that are installed on your device.

A very simple way to solve this problem is to find and download the appropriate application. The first part of the task has already been done – the software supporting the QBK file can be found in the table. Now just download and install the appropriate application.

Possible problems with the QBK format files

The inability to open and operate the QBK file does not necessarily mean that you do not have an appropriate software installed on your computer. There may be other problems that also block our ability to operate the QuickTax Backup Format file. Below is a list of possible problems.

  • Corruption of a QBK file which is being opened
  • Incorrect links to the QBK file in registry entries.
  • Accidental deletion of the description of the QBK from the Windows registry
  • Incomplete installation of an application that supports the QBK format
  • The QBK file which is being opened is infected with an undesirable malware.
  • The computer does not have enough hardware resources to cope with the opening of the QBK file.
  • Drivers of equipment used by the computer to open a QBK file are out of date.

If you are sure that all of these reasons do not exist in your case (or have already been eliminated), the QBK file should operate with your programs without any problem. If the problem with the QBK file has not been solved, it may be due to the fact that in this case there is also another rare problem with the QBK file. In this case, the only you can do is to ask for assistance of a professional staff.

How to associate the file with an installed software?

If you want to associate a file with a new program (e.g. my-file.QBK) you have two ways to do it. The first and the easiest one is to right-click on the selected QBK file. From the drop-down menu select "Choose default program", then click "Browse" and find the desired program. The whole operation must be confirmed by clicking OK. The second and more difficult to do is associate the QBK file extension to the corresponding software in the Windows Registry.

Is there one way to open unknown files?

Many files contain only simple text data. It is possible that while opening unknown files (e.g. QBK) with a simple text editor like Windows Notepad will allow us to see some of the data encoded in the file. This method allows you to preview the contents of many files, but probably not in such a structure as a program dedicated to support them.
