An AJP file using the .ajp extension can differ based on source because different systems may generate it, though it’s most often a CCTV/DVR export where video is stored in a proprietary format that VLC or WMP won’t open, created when someone exports a chosen camera and time span to USB or disc, usually accompanied by a special viewer such as a Backup Player / AJP Player that can open the footage and sometimes re-export it.

If the file wasn’t produced by a CCTV system, an AJP may be tied to legacy tools like Anfy Applet Generator or CAD/CAM utilities like Alphacam, which means it isn’t video, and you can figure out which one you have by inspecting file size and folder neighbors—camera-export AJP files are often hundreds of megabytes or more and may show up next to player executables, while project-type AJP files are small and appear beside web or CAD items, and checking the file’s Properties or glancing at it in a text editor can reveal readable config-like text for project files versus unreadable binary for DVR exports.

To open an .AJP file, the right solution hinges on what generated it because Windows and everyday media players can’t interpret AJP formats on their own, and when the file is from a CCTV/DVR backup, the safest method is to launch the bundled viewer/player—often included in the same export folder and named something like Player.exe or BackupPlayer. If you have any concerns concerning in which and how to use AJP file compatibility, you can get in touch with us at our website. exe—then load the AJP inside that tool and use its built-in export or convert option to obtain a normal video file like MP4 or AVI.

If no matching viewer is provided, you should identify the recording platform and download the official CMS/VMS or backup viewer, since many CCTV vendors restrict AJP playback to their own client; open the client first, use its Open/Playback/Local File menu to select the AJP, and if the file plays but cannot be exported, the last possible solution is screen-recording the playback, which can degrade quality but may be the only option with older formats.

If your AJP isn’t linked to CCTV footage, it could be a project file for old animation/applet generators or CAD/CAM systems, which must be opened with their respective software, so scan the folder for app identifiers, documentation, or CAD-style files and then load the AJP inside the appropriate program, using the file size as a quick clue—large indicates CCTV, small indicates project/config data.

If you prefer, you can give me the file 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.
