DSF file is used by DAZ Studio. This application is used for making 3D models of objects. The asset file stores the rendering information related to any specific object modeled in DAZ Studio.
DSF file also saves the mesh information of the object, its respective place from the origin and the dimensions of the object. This file can be used to render and animate a specific object in an environment. The object can have interaction with the scene or other objects as well and all this detail is stored in an asset file of the object. In case of the scene the asset file also stores information related to depth of field and 3D motion blur.
In addition to the problem described above, i.e. the lack of the appropriate application to support the .DSF file, there may be several reasons that cause problems with opening and operation of the data format:
A quite common problem is the lack of application in the appropriate version. Even if you have an application, with the help of which you should open the .DSF file, you may have a problem with it because of its version. Perhaps in previous versions the application has not yet supported the .DSF file, so download the update and check again.
If you have already installed the appropriate application, and it is the correct version, the file may not open correctly, because the operating system does not have information that this program supports the file. So you need to "show" which program the computer should use. To do this:
It also happens that the file you want to open is corrupt and therefore there is no such possibility. In this situation, you should find its different version, or ask a person from whom you got, to send it again.
