I have a text file that contains about 200000 lines with basically notes, with the most recent notes on top of the file, and the oldest notes at the end of the file. I want to convert it to a orgmode-compatible file so I can use the cool features in orgmode, like displaying images live in the editable emacs buffer. The problem is that when I just rename my file notes.org and start emacs on it, emacs starts churning, eating CPU cycles and doesn't load the file. Supposedly this is because the file is too large, or contains something that brings orgmode to an endless loop. So I am wondering if there are ways of finding out why it's breaking, or forcing orgmode to load or parse only the head of the file, which is what I'll be editing in the end.
Ideally I would not like to chop the file into pieces, since I use emacs search to navigate across all the notes in the file.
So how can I open my large file in orgmode as instantaneously, or close, to a simple txt mode? Any suggestions?
