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 configura
You can also find out directly from Notepad++ and change where it stores this vital information. As mentioned in this answer look in Settings > Preferences > Backup: Backup path. There are also other useful settings such as backup frequency.
You can also find session.xml which shows information on the temporary, unsaved files in its parent directory.
