.DDB File

File extension ddb is associated with the Device dependent bitmap graphics file format.It is similar file format to BMP.

A device-dependent bitmap (DDB) is structured in such a way that it matches very closely the form in which the bitmap is finally displayed by the device driver. For this reason the DDB is unlikely to be compatible with other display devices.

A device-independent bitmap (DIB) on the other hand has a logical layout and can be decifered by any device driver. The disadvantage with DIB though is that it is much slower to render onto the device as compared to a DDB.

How to open:

Use ACDSee or similar image viewer to open and possibly edit *.ddb bitmap graphics files.

How to convert:

Images can usally be converted between various graphics format, provided you find a converter that supports *.dbb files.
