SPD file format is created by SSPD software application which is used for statistical analysis. This software stores custom dialogue box which is stored in the format of SPD.
This is a custom user interface component that is created by the user. This user interface is then used by professionals to create their input forms and create custom functions for calculation. The SPD file format contains all the information related to the custom dialogue box and as it is a plugin file therefore the data required for complete execution of the custom dialogue box is also present in SPD file.
In addition to the problem described above, i.e. the lack of the appropriate application to support the .SPD 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 .SPD file, you may have a problem with it because of its version. Perhaps in previous versions the application has not yet supported the .SPD 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.
