A .memb file is a temporary file used by Pro/ENGINEER, the CAD software from PTC.
It is an internal working file rather than a user document intended for independent use.

The MEMB file extension was used for one of the temporary files generated by Pro/ENGINEER. Pro/ENGINEER, later known as Creo Elements/Pro, is PTC's mechanical computer-aided design software.
A .memb file is used for temporary processing during the software's operation. It is not a primary design file or a general-purpose interchange format, and its contents are intended to be managed by Pro/ENGINEER rather than edited by the user.
This file type is associated with the Microsoft Windows version of Pro/ENGINEER.
A .memb file normally should not be opened manually. It is a temporary Pro/ENGINEER file intended to be managed by the software.
If the file is needed for recovery, keep it in its original location and try the related work in the same Pro/ENGINEER installation on Windows. Do not rename it or use another program to edit it.
A .memb file cannot normally be converted meaningfully because it is a temporary working file, not a document or exchange format.
If it contains recoverable design data, open or recover the work through the appropriate Pro/ENGINEER session and use that software's normal save or export functions. Otherwise, there is no practical conversion procedure for the file itself.
