File size problem - File is too big to be opened by Notepad++

Ekopalypse · Feb 21, 2020, 2:05 PM

but after some quick searches in Google is seems that there should be no issues with opening files under 2GB

Depends, what npp version are you running?
See and post debug-info from last menu, the ? menu.

@Ekopalypse using npp v.7.8.3 32-bit

@Adam-Dendy said in File size problem - File is too big to be opened by Notepad++:

32-bit

That means, as far as I’m aware, that npp itself can have only
~2GB of RAM allocated in total as the other halve gets used by the OS.
Every open documents counts.
If the file you want to open is a file which gets lexed,
meaning colored by a lexer, then scintilla has to allocate additional
RAM which might end up in double the size of the file.
Npp identifies which lexer gets assigned via the extension of a file.

So in order to get your file opened, you might test to start another
npp instance without any document open and if needed to rename the
file to a .txt extension as this one is, normally, assigned to no lexer.

Another suggestion might be to grab a portable 64-bit version of Notepad++ and see if it can open the file. If not, maybe add to that some of @Ekopalypse 's suggestions. And if you finally get the file open this way, maybe consider a permanent move to Notepad++ 64-bit?

I didn’t manage to get it opened changing it to .txt - I will try using the 64-bit version and hopefully this will resolve my issue.

@Alan-Kilborn have downloaded and installed 64-bit version and success! Thanks for the tip off, appreciate both yours and @Ekopalypse ’ help!

Same problem for me. 388MB file and notepad++ cannot open it. What a fail.

@Pavel-P ,

I have opened files that big or bigger in Notepad++, so Notepad++ can open a 388MB file.

If you have a problem, you need to describe the circumstances of the problem with more detail than that. Please see https://community.notepad-plus-plus.org/topic/15739/faq-desk-request-for-help-without-sufficient-information-to-help-you, then come back and give us something to work with.
