DB file extension is used by a vast variety of programs involving creating and editing databases. DB file extension usually indicates that this file stores information in a form of a structured database.

DB file format stores data in a form of arranged tables, table fields, field data types and field values.  Those files are pretty generic and typically contain a spreadsheet or a table filled with information of every kind imaginable, from a to-do list to a complex secured bank account data.

Various programs use DB file format, especially ones that allow users to create databases of their own. Mobile devices like iOS, Android and Windows Phone share a tendency to use the DB file format as well, in general they use it to hold SMS data, user’s contacts, device and application data. Those files are usually encrypted to prevent users to meddle with vital for device’s functioning information.

It happens once a time that some DB files have nothing to do with databases at all. For example, Thumbs.db uses Windows Thumbnail Cache format to store thumbnails (small image previews). One can see those little thumbnails representing graphic (mostly, images) contents that a folder holds.

Another example of a DB file that would not have spreadsheets of data is the main.db file designed by Skype developers to store chat history. If this file is transferred to another device, this device’s installed Skype would show chat messages transferred from a new file.

How to Open and Edit DB Files

DB files concerning databases are plain text files and this means that those DB files are pretty much ready to be opened with Notepad or any other text editor. But be aware, that DB files are not tables in substance. To view DB files as tables, DB file viewer should be used.

Microsoft Access can be used to open a DB file, so can Microsoft Excel. DB files would probably be exported in .ACCDB or .XLS file format as those formats are proprietary for their respective programs and it would be easier for a program to work with a familiar file type.

Oracle Database is a free DB file viewer. It also provides the capacity to edit DB files intact or to export those files to its native .SQL file format. LibreOffice has this feature too, but it will not unexpectedly convert DB file to any other format because of its multi-format support. In addition while a lot of DB file viewers work predominantly in Windows, LibreOffice works in Windows, Linux and Mac.

For those who don’t work with DB files on a regular basis there is also a possibility to open DB files online.

To open Thumbs.db  user might consider Thumbs Viewer or Thumbs.db Explorer, though one wouldn’t find inside them anything new due to thumbnails being a smaller version of images that are already in the folder.

Main.db can be viewed with a usual database file browser.

How to Convert DB file to Other Formats

Since DB files consist of plain text, they can be converted to any other text-based formats like CSV, TXT, HTML or XLS. For example, Microsoft Access’ and Oracle database’s Export or Save As options are used to do so. Other DB converters usually share the same trick.

Conversion of DB file to other formats can be performed online on various websites covering this need.
