BANK file format:

Why is it important to know the file format? This is the only way to find out which program to use to open the file. Each file format has a unique extension and almost always a unique signature. For example, Microsoft Word documents have the extension .docx and the signature (usually the first 3 characters in this file) PK. Frequently, however, one file extension is used by different programs for different file formats, and one file format for different file extensions. If there are problems opening a file, you must first determine the file format used. Our examination of the BANK files comes to the following conclusion:

BANK is a very widely used file extension. The file type predominantly uses a uniform format. The two most common formats are as follows:

• 98% of all BANK files are Music files, which are based on the RIFF file format. RIFF files store data in tagged chunks. There are primarily used to store multimedia such as sound and video. They consist of unreadable binary data. BANK files are between 70 KB and 130 MB in size. It is a modern file type. Certain words are almost always found in the files, such as PROJBNKI, FEV FMT, LIST, IBSSLCNT, IBUSIBSB*, RIFF, LISTp and BUS %. The file name Music.bank is typical for these files. Files like these are about master, assets, dialogs, crew, aircraft, strings, common and tanks.
• 1% of all BANK files save the data in SQL file format. An SQL file contains a lightweight SQLite database, widely used in application development for storing application related data. These files are binary files, so they do not contain text, but only cryptic characters. BANK files can be up to 180 MB in size, but are often around 20 KB - 50 MB. Certain words are almost always found in the files, such as SQLite format 3. Some examples of file names are debug.bank.

The remaining 1% of all BANK files are different files with different signatures. The category is ground, voice, hero, weapons, engines or audio. If you want to find out what your BANK file contains, drag and drop it onto this page.
