The ASP file extension stands for the Active Server Page. These files comprise of the ASP file type that consists of the scripts which are useful in generating the HTML pages. It is that when your browser requests for an ASP page, the server is going to generate the content and will be displayed to the user in the web browser. The pages does not just download the requested page, but has been built by the server at the request of the particular user.
The sites that are hosted on the Microsoft IIS servers normally make use of the ASP file formats.
In addition to the problem described above, i.e. the lack of the appropriate application to support the .ASP 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 .ASP file, you may have a problem with it because of its version. Perhaps in previous versions the application has not yet supported the .ASP 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.
