Large Text Files
Older versions of Notepad++ may crash while opening very large files. Newer versions (5.2+) will deny opening the file and issue an error message. Why is that?
Notepad++ is based on a component (Scintilla) which is geared towards providing rich ext viewing, with syntax highlighting and code folding, as opposed to bulk text services. There are necessary trade offs. Loading a 200Mb file will require around 800Mb of memory, and the OS may balk at the memory allocation request.
There are basically two ways out:
- Split the huge file into manageable chunks, and keep only one of them in editor;
- Use another tool which is tailored to handle massive text files.
If you still manage to open a large file, performance may not be optimal. Here is a couple things to think about:
- Plugins which analyse and scan text will slow down NP++, disable them if possible
- Parsing for clickable links on loading the document is slow if the document is large; disabling the clickable links has been reported to significantly help.
