Windows 10. Are there any free text editors that can read any size file, not limited to memory size?

I like Notepad++, but every application is limited in one way or another to the amount of RAM in the computer it's running on.

Another vote for Notepad++, whenever a big file freezes Notepad, I think, "ouch should've use d Notepad++". Obviously, if the file is terribly big, it takes a while to load, even with Notepad++. The efficiency between Notepad and Notepad++ is still notable though.

I have not tried it on a monster file, but there is now a 64-bit version of Notepad++

It still loads everything into memory (like the 32-bit version), but being a 64-bit app, the potential size limit is very high. Be sure to download the 64-bit version, not the 32-bit one.

conTEXT supports unlimited file size, but there's a 4KB limit on line length:

There are other editors that support reading parts of files into memory, instead of the entire file, so they are not limited by memory size. I believe that Gawk is one of those, but I've never used it:

Manual is here:

Please post back here to let us know what works for you — I'm very curious. Thanks, Joe

MadEdit is my favourite text editor and it can read a text file up to 32gb.

Did it give an error message and/or number?

> Same with ConText

Did it give an error message and/or number?

How big is the file and what type of data does it contain?

Is your W10 32-bit or 64-bit?

OK, unless you have a 128GB RAM W10 machine, you'll need a text editor that supports disk-based editing, such as UltraEdit:

Problem is, it's not free, although it does have a 30-day, fully functional (all features!), free trial:

Regarding Gawk, as I mentioned earlier, I've never used it, but I'm pretty sure it is a disk-based editor with no file size limit. I don't know of a Windows binary for it, so unless you can find one, I would download the latest archive, which is Version 4.1.4, dated 2016-08-25, and try to make a Windows binary from that, but I don't have a clue how to do it.
