Issue:

Drawings cannot be opened from certain file paths but can be opened from the desktop. An "Invalid File Name" message appears.

Causes:

The error occurs when the file's storage path or the filename is too long, or the filename contains special characters.

Solution:

Shorten the file path, remove special characters from the path or file name.
