.DEP1 File

The dep1 file extension is used for one of the Data Exchange Protocol files.

The data exchange protocols (DEP) define logical sets of the complete data at defined stages in the process, from analysis through design and fabrication.

The dep1 file contains analysis data.

Seems like it was used in the past in some 3D engineering software.

This dep1 file type entry was marked as obsolete and no longer supported file format.

This type of file is no longer actively used and is most likely obsolete. This is typically the case for system files in old operating systems, file types from long discontinued software, or previous versions of certain file types (like documents, projects etc.) that were replaced in higher versions of their original programs.

How to open:

Use compatible tools to work with *.dep1 files.

How to convert:
