What is a DB file?

DB files mostly belong to Windows by Microsoft. DB file extension is associated with database files that are encountered in Windows, iOS, and Android smartphones.

Main Use: DB stands for the Database file and is commonly found in smartphones. DB files mainly contain contacts and SMS related information but can also store data specific to a certain application on the mobile device. The data in the DB file is generally stored in SQLite database format and is often encrypted thereby denying direct access to the user. DB files on smartphones are not intended to be opened on the user front as they contain information related to the smooth running of a particular application on the device.
Other Uses: DB files are also used by Microsoft Windows as cache files that store thumbnail image data of photos and are generally hidden from the user's view. QQ is a Chinese online chatting application that uses DB files to store the contact list or online chat log belonging to a specific user. Skype, an online communication tool, uses the DB file format to save the data consisting of instant messages and audio/video call sent and received by the user.

How can I open a DB file?

You need a suitable software like Windows to open a DB file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your DB file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a DB file directly in the browser:. Just drag the file onto this browser window and drop it.

DB file extension format:

The file format, which is the arrangement and type of data in a file, determines which program can open the file. The initial characters of a file are called signature, sometimes also referred to as "magic bytes". The signature can be used to infer the file format. Nonetheless, different programs can utilize the same file extension to represent distinct file formats. Double-clicking on the file often results in an error when opening. So a detailed analysis of a file is vital in order to determine the format and the associated program. In the following you will find our evaluation of the DB files:

The DB file extension is very common and primarily uses a special format that can be read by various programs. The two most popular formats are as follows:

50% of all DB files are using the well-known SQL file format to store the data. An SQL file contains a lightweight SQLite database, widely used in application development for storing application related data. They consist of illegible, cryptic characters. The average file size is 86 KB with most files being between 12 KB and 6 MB in size. The file type was developed only in the last few years. Several words can almost always be found in the files, e.g. SQLite format 3. Files like these have the following tags: cache, databases, data, database, history, manifest, activities and backup.
7% of all DB files are based on the Microsoft Compound File format, which is also known as Compound File Binary File format (CFBF or CFB) or OLE2 Compound Document format. This Windows file format has features similar to those of a filesystem format with virtual files and subfolders. Compound files begin always with signature bytes D0 CF 11 E0 A1 B1 1A E1 (ÐÏà¡±á). The app name of DB files is Windows Installer XML. There is also a CLSID, a globally-unique identifier of a COM (Component Object Model) object: 000c1084-0000-0000-c000-000000000046 or 000c1086-0000-0000-c000-000000000046. The file contains several sections which are named like 1. The files are 6 KB to 420 KB in size, with a median of 43 KB. A common filename is Thumbs.db or _Thumbs.db. Such files sometimes refer to registry.

The remaining 43% of all DB files are files with no common format, such as LiteDB DataBase, Berkeley DB, Everything Data Base, ZIP, JSON, plist, UTF-8, block, CMMM, tsd, Win, REMF and MEM. These files are often connected to contact, icon, local, observations, lightspeed, messages or memo. You can get all the details of your DB file by dragging it onto this page or by clicking the button "Choose your .db file to view" above.
