AJP File Won’t Open? FileViewPro Has the Answer > 자유게시판

An AJP file in the .ajp format depends on the system that made it, most often acting as a CCTV/DVR backup where the device stores video in a proprietary container that normal players cannot open, produced when a user exports a selected channel and time window to a USB stick or disc, and commonly bundled with or requiring a viewer such as a Backup Player / AJP Player to access or convert the footage.

If an AJP doesn’t come from a DVR or camera system, it may be associated with older software like Anfy Applet Generator or CAD/CAM processes such as Alphacam, meaning it isn’t video, and the easiest way to identify which type it is involves looking at size and folder context—CCTV AJP files are commonly very big and may be accompanied by a viewer program, while project-oriented AJP files are smaller and appear with web or CAD materials, and checking Properties or doing a non-destructive text-editor peek can differentiate readable project text from binary DVR data.

To open an .AJP file, your approach depends on the device that made it because common media players and Windows do not automatically understand it, and with CCTV/DVR exports, the best approach is to locate the companion viewer/player—commonly included in the same folder under names like Player.exe or AJPPlayer.exe—run it, open the AJP through its interface, and then use its export or convert function to generate a standard video format such as MP4 or AVI.

If nothing came with the AJP file, your best move is to determine 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 causes quality loss but sometimes unavoidable.

If the AJP didn’t originate from surveillance equipment, it might relate to outdated animation tools or CAD/CAM software, meaning it requires the original application to open it, so check the surrounding folder for hints such as project-related filenames, readmes, or CAD formats like DXF/DWG, then install the correct program and open the file through it, noting that smaller sizes usually fit project files while very large sizes resemble CCTV containers.

If you want, you can paste 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 determine whether it’s surveillance footage and suggest the most likely viewer/player that will open it.
