Hello @Anonymous!

I have run into this before; it appears the software includes the file structure in the folder name - so if you file is located inside a folder, inside of another folder, etc.  each folder name adds to the total file name.

Try moving the file to the desktop to see if it will open.  If it does, you may need to change your file names/structure as well as the actual file name.

(keep in mind this affects XRefs, too).

Hope this helps,

Kenny

This happens when people use entire sentences for directory names (with spaces and punctuation), those people should be knee-capped.  There is no intelligent reason a directory name needs to exceed 10 or 12 characters.  If I know the project number i don't need the project title, client name, address and eye color included int he directory name.  We worked without issue for years with an 8 character limit.  Just because you can, doesn't mean you should.

""Individual components of a filename (i.e. each subdirectory along the path, and the final filename) are limited to 255 characters,""

Hi @Anonymous,

Have you tried temporarily renaming the file to something like 1.dwg? If that works then you need to consider the filename as well as the filepath.

What is the current path and filename?

And yet another possible solution...

Map a network drive to the grandparent folder (or similar).
Then, select that network drive and browse to the file.
Double-click.

Example:
X:\test\your\knowlede\of\the\network\drive\for\AutoCAD\Projects\Files\Drawing1.dwg

Map a drive (Y:) to:
\\test\your\knowlede\of\the\network\drive\for\AutoCAD

The result:
Y:\AutoCAD

???

To resolve these issues for currently Windows versions or windows servers is a software named "LONG PATH TOOL", I suggest everyone a software “Long Path Tool“ which can solve all the long path problems.
