You're here because you have a file that has a file extension ending in .avp. Files with the file extension .avp can only be launched by certain applications. It's possible that .avp files are data files rather than documents or media, which means they're not meant to be viewed at all.

Files appended with the .avp extension are data files associated with software developed by Avid Technologies. The Avid Media Composer software and the Avid Xpress application use files in the .avp format as the output format of projects developed by users with these programs, and these AVP files are also called Avid project files. The data of these AVP files are the configuration settings and other details entered and saved by the user through the features integrated into these Avid Technologies multimedia development programs. The data of these AVP files are referenced by these applications when a user views, opens and edits a project saved in the AVP format. These details stored in an AVP file are directory locations of digital video files and audio tracks entered by the author of the AVP project output file. The Avid Media Composer is available in versions that support Microsoft Windows-based systems and Mac platforms. There are also versions of the Avid Xpress application for Microsoft Windows environments and Mac systems. When a user of any of these operating systems install the Avid Media Composer software or the Avid Xpress, support for these AVP files will be implemented into the system by the installer packages of these programs. Users can then start creating, opening and editing multimedia development projects saved in the AVP output format, and these AVP files will also contain reference details of the effects and other attributes integrated into those project output files by the project creator through the features available in these applications.

Launch a .avp file, or any other file on your PC, by double-clicking it. If your file associations are set up correctly, the application that's meant to open your .avp file will open it. It's possible you may need to download or purchase the correct application. It's also possible that you have the correct application on your PC, but .avp files aren't yet associated with it. In this case, when you try to open a .avp file, you can tell Windows which application is the correct one for that file. From then on, opening a  .avp file will open the correct application.

Be careful not to rename the extension on .avp files, or any other files. This will not change the file type. Only special conversion software can change a file from one file type to another.

A file extension is the set of three or four characters at the end of a filename; in this case, .avp. File extensions tell you what type of file it is, and tell Windows what programs can open it. Windows often associates a default program to each file extension, so that when you double-click the file, the program launches automatically. When that program is no longer on your PC, you can sometimes get an error when you try to open the associated file.
