QBF file format:

Every file has a defined file format, i.e. how the data is arranged in the file. Often, the file format can be deduced from the file extension or the initial bytes (called the signature). However, different programs can use the same file extension. Furthermore, a file extension can be renamed incorrectly and double-clicking on it will then display an error when it is opened. Exact knowledge of the format is therefore important in order to solve problems occurring in files. Our evaluation of the QBF files is as follows:

The QBF file extension is rarely used and includes different formats for different programs. The following file formats are most commonly found in QBF files:

• 30% of all QBF files are based on the zip format, so several files are compressed and saved in one QBF file. 4 to 30 compressed files with names like Board.xml are common. If you want to see the included files and images, simply rename the file extension to .zip and double-click it. The files are 150 KB to 1 MB in size, with a median of 640 KB. Certain words are almost always found in the files, such as Board.xml.
• 25% of all QBF files start with the bytes PAA/AHgAbQBsACAAdgBlAHIAcwBpAG8AbgA9ACIAMQAuADAAIg, which are crucial for this file format. These files are text files, so they contain words and text. QBF files are between 8 KB and 28 KB in size. The following keywords are characteristic: PAA/AHgAbQBsACAAdgBlAHIAcwBpAG8AbgA9ACIAMQAuADAAIgAgAGUAbgBjAG8AZABpAG4AZwA9ACIAdQB0AGYALQAxADYAIgA/AD4ADQAKADwAIQAtAC0AUQB1AGUAcgB5ACAAQgB1AGkAbABkAGUAcgAgAEQAZQBmAGkAbgBpAHQAaQBvAG4ALQAtAD4ADQAKADwA.
