File Extension DB Description:

The most recognizable reference to the file extension .db is in relation to a database file, which is created by any of the numerous database management languages. The file extension .db may be considered as a generic format for databases; however, there are specific languages that particularly implement it.

One of the more common database development languages to default to the file extension .db is the Paradox, which unlike many programs have shifted their use to make the format more recognizable, like in the case of Microsoft Office Access, which commonly defaults to the MDB format. The Paradox program is one of the more successful software to make the migration from MS-DOS to Microsoft Windows Operating System environment.

Usually, databases like the file extension .db are prone to corruption, because they expectedly grow tremendously complex and even very large. This is the reason why many programs (not only those that utilize the file extension .db) incorporate a utility that will help to monitor and organize the user's databases, providing useful features like repairing and maintenance to resolve issues.

These types of utilities that are commonly associated with the file extension .db however are not fully equipped to identify problems that may be hardware related, like for example a bad sector that caused the corruption.

Another usage for the file extension .db can be seen in the Microsoft Windows Operating System platform itself, in relation to its caching capabilities. The file extension .db is specifically utilized by the operating system in association to thumbnails that represent images and movies, which are stored in the user's hard drive. The file extension .db provides the user with an insight on the contents of the file via its image displayed on the screen, based on the last known contents of the file.

This process is intended to facilitate the display of images, rather than have the operating system refresh it every time that the user accesses it. The file extension .db will store approximately two kilobytes of information on the hard drive related to the image file it represents. There are particular instances wherein the file extension .db is not automatically refreshed by the operating system, like for example if the file is frequently modified.
