PyCharm File size exceeds configured limit (2,56 MB), code insight features not available

Question

I'm working with some big txt files, (some around 3 GB), and whenever I have to check the txt files the message "File size exceeds configured limit (2.56 MB), code insight features not available" appear in the top of the file, I tried to change the file size by going to Help->Edit custom properties and then adding the next line of code in the file that opens

idea.max.content.load.filesize=500000

the problem is that even after closing and re-opening PyCharm the same message appears, do I need to do something else? just writing that line of code is enough to change the filesize?, it doesn't need to be run like a normal code? if so how can I run it since the option doesn't appear?

Answer 1

Instead of using the original line of code use:

idea.max.intellisense.filesize = new size in kB

in the window that appears after going to Help->Edit custom properties

After changing it, restart PyCharm for the new setting to take effect.
