An AJP file with extension .ajp changes meaning depending on its creator, usually showing up as a CCTV/DVR backup where the device saves video in a proprietary container that normal apps can’t read, generated after selecting a camera and date/time for export to USB/CD/DVD, and typically relying on a companion viewer such as a Backup Player or AJP Player to view and sometimes convert the footage.

If the file wasn’t produced by a CCTV system, an AJP may come from 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 correct method varies based on the software or device that created it, since Windows and common media players can’t automatically detect the proper format, and if the file came from a CCTV/DVR export, the most reliable option is to use the matching viewer/player that accompanies that DVR system, typically found in the same USB/CD/DVD/folder as the AJP and named something like Player. If you are you looking for more information on AJP file unknown format have a look at our own site. exe, BackupPlayer.exe, or AJPPlayer.exe, which you can run to load the file and then use its own export or convert feature to produce a standard MP4 or AVI.

If nothing came with the AJP file, your best move is to find out the DVR/NVR brand or the software normally used for live viewing, then install the vendor’s official CMS/VMS/backup player, because many systems only decode AJP through their own client; after installation, open that client manually and use its Open/Playback/Local File function to load the AJP, and if playback works but export is unavailable, the last workaround is a full-screen screen recording, which is time-consuming but sometimes unavoidable.

If the AJP file doesn’t trace back to a DVR, it may represent older animation/app-creation tools or CAD/CAM workflows, requiring the same program that made it, so look around its folder for identifying app names, documentation, or related file types like DXF/DWG, then open it inside the correct software, noting that file size can guide you—tiny files usually mean project/config content, while huge ones are often CCTV backups.

If you want, you can tell me the file size and a few filenames from the same folder as the AJP—or even provide a quick screenshot—and with that information I can usually tell if it’s a DVR export and suggest the most likely viewer/player that will open it.
