The da_ file extension is associated with GKSetup, an installation-package creation program developed by GkWare e.K. for Microsoft Windows.
A da_ file stores support data that GKSetup uses while creating or managing installation packages. It is an internal data file rather than a document intended for independent use.
Its contents are specific to GKSetup and are not intended to be edited manually.
Open the da_ file with GKSetup on Microsoft Windows.
Because it contains GKSetup support data, it is not normally useful as a standalone file in another application.
A da_ file is internal GKSetup support data, so it has no practical standalone conversion to a common file format.
Use GKSetup to work with the associated installation package or project. Do not convert the file separately if it is needed by GKSetup.
