Question: I am using Notepad++ on my Windows machine and by mistake I opened a 64MB file. Now my Notepad++ is stuck permanently and I am not able to use it.

Is there any configuration file which Notepad++ uses to maintain the list of opened files? If yes, then can I open that file and remove the entry of the 64MB file which I have opened in it?

Answer: 
**if your notepad++ have been installed.**

there must be in : 

%appdata%\Notepad++\session.xml

**if your notepad++ is portable**

there must be in : 

your notepad++ programs folder.

the file for notepad++ portable or notepad++ installed is same:

`session.xml`
This article helped me figure out how to move/copy my unsaved open tabs to another PC.

Install notepad++ first if not already.

Make sure notepad++ is not open/running on new PC.

On the old PC copy the backup folder located C:\Users\xxxx\AppData\Roaming\Notepad++ to the new one (location may vary on OS). Also copy the session.xml file.

Open notepad++ and all the open unsaved tabs should appear with content.
