Hello

What could cause this error ? I'm trying to open an assembly from my computer.

" Could not open :\xxxxx.prt -Invalid filename."

  • 2nd error also happens after 1st sometimes "Failed to load a part file when responding to request from another application."
  • There are no strange:Ä,Ö-alphabets in the folder name.
  • Tried restarting PC.

Hi @12131444,

 

I would suggest opening an IR with GTAC and have them review your NX log file.

 

Regards, Ben

I would try loading structure only, if you can.

Then open subassemblies.

This usually fixes it for me.

Don't ask why, no answer there.

That might work if the part reported as "invalid filename" was a component (or a sub assembly). If it's the assembly that's raising the error then I suspect there's no solution other than contact GTAC or revert to a previous backup.

Does the problem continue if you disable "Partial Loading" and "Load Interpart Data" in the Assembly Load Options?

You can meet "invalid file name" error under some case as below.

1. Too deep level directory path.
The complete path of the file over 19 directory levels deep.

2. Too long file name.
NX limits the maximum length of a file name to 248 bytes, whereas maximum length of a full file specification to 256 bytes.
(These file specifications include directory name, subdirectory names and filenames)

3. The file name is including invalid ASCII character ( “ * / : < > \ ' | )
You cannot use any non-ASCII character (including 8 bit accented Western European and multi-byte characters) for a file name.
