Shorten filename to certain lenght max characters

What should be the correct code to shorten the filename by a max amount of characters?

I tried to use <Subst:0:40> but I cannot use it because it says that there is the error of have same filenames.

You can use that tag in the New Name method to shorten the filename. But I think you might have spelled it wrong. It should be spelled <Substr:0:40> not <Subst:0:40>

Another way to get there is to use the replace method:

Text to be replaced: (.{40})(.*$)
Replace with: \1
Use regular expressions (checked)
Apply to: Name

The (.{40}) selects the first 40 characters in the file name, so you can change that number to be whatever length you need.

File names shorter than 40 characters won't be changed.
