An AJP file saved as .ajp can represent different things depending on what created it, so its origin is the key clue, with the most common case being CCTV/DVR backups where the system saves recorded footage in a proprietary container that normal players can’t open, produced when a user selects a camera and time range to export, usually writing the file to a USB stick or disc along with a viewer like a Backup Player or AJP Player that can play the footage and sometimes convert it to a standard format.

If it didn’t originate from a camera system, an AJP file may serve as a project file from older tools like Anfy Applet Generator or be tied to CAD/CAM platforms such as Alphacam, in which case it has nothing to do with video, and you can narrow it down by reviewing file size and folder contents—CCTV versions are substantial in size, often packaged with viewer apps, while project-based AJP files are much smaller and live among web or CAD resources, and by checking Properties or safely viewing it in a text editor, readable text usually signals a project/config file while unreadable binary points to DVR footage.

To open an .AJP file, you need a method that fits its origin, since Windows and typical video software don’t know how to open it, and if it’s a CCTV/DVR export, your best bet is the viewer/player supplied with the footage—often located in the same folder and named something like Player.exe or BackupPlayer.exe—which you can launch to load the AJP and then use its built-in export/convert tools to save out an MP4 or AVI.

If the AJP came without a viewer, the next logical step is to determine the DVR/NVR model and install the vendor’s CMS/VMS/backup viewer, since many systems decode AJP only through their own PC client; once set up, open the client itself and load the AJP via its Open/Playback/Local File feature, and if playback works but exporting doesn’t, your final fallback is to record the footage from the screen, which is time-intensive but can be necessary for older or locked-down formats.

If your AJP didn’t come from a camera system, it may be tied to an older project/animation tool or a CAD/CAM workflow, meaning it opens only in the software that created it, so the best approach is to inspect the source folder for clues—such as app names, readme files, project folders, or CAD-related extensions like DXF/DWG—then install that application and load the AJP from within it, using file size as a hint since large files usually indicate CCTV footage while smaller ones suggest project/config data.

If you prefer, you can tell me the size along with names of nearby files or a screenshot, and I can almost always confirm if it’s a DVR export and advise which playback tool will open it.
