What is the EZP file format?
.ezp files belong to the category of CAD archive files.
.ezp files contain compressed backup copies of CAD projects. The resources in these files are used by AutoCAD ECSCAD, which facilitates the design of electrical circuits and electronic schematics. Note that .ezp is a project backup format - the active working project uses the .epj primary project file format.
.ezp files are primarily used for archiving projects within AutoCAD ECSCAD. The applied compression reduces the disk space reserved by a project. Packaging also enables bundling multiple design resources into a single file, which is practical for extensive projects. .ezp files can be stored on hard drives, USB drives, optical media, or distributed via file-exchange platforms.
The .ezp extension is also used by EDIUS (Grass Valley) for compressed video-editing project archives, so the extension is shared between two unrelated applications. When encountering an .ezp file, the application that created it determines which tool is needed to open it.
AutoCAD ECSCAD has not been actively developed since 2013, so .ezp files are not commonly encountered today. Existing files can still be opened in older installed versions of the dedicated software.
Security & safety
RISK: LOWCAD and video project backup files; no known executable payload risk. Treat as proprietary data files.
Format details
in a nutshell- EDIUS Compressed Project (Grass Valley/Thomson) - EDIUS non-linear video editing software uses .ezp for compressed project files - a ZIP archive of timeline, settings, and media references.
- EZ-PLC Project (AutomationDirect) - EZ-PLC ladder logic editor uses .ezp for PLC program project files.
