It is usually the file path not the file name that is too long.


File path including the parent folders of the file is too long, try shortening the length of the folder names that it is contained in until you get it open. then once it is open save as a different name and then rename the folders back to what it was.



How to Fix ‘This file name is too long’ Error?

The solution to this stupid error is also a bit silly. However, it is tried and it worked on every time.
  1. You just need to follow the following steps:
  2. Open the folder that contains the long name error file.
  3. Go to the first parent folder (the folder containing this file) and rename the folder to a very short name, 2 or 3 characters are enough. For Example, the problematic file named ‘our_intro.mp4’ exists in the folder ‘Chapter_01 A Brief Introduction of Our Well Known Well Established Company’. You need to change this folder name to some very short name such as ‘Int’ or any other short name.
  4. Now open the file, and it should open without any problem or error message.
