Notepad++ is available in a 64-bit version in addition to a 32-bit version.

What benefits does the 64-bit version of Notepad++ have over the 32-bit version when running in Windows 7? What about in Windows 10?

I imagine one of the benefits is being able to load enormous, multi-gigabyte files. Is that correct? Are there other benefits?

EDIT 1: There seemed to be much interest in the release of a 64-bit version of Notepad++, but it's hard to imagine that so many people are using it to edit files over 4GB in size, even if multiple files are open. That made me wonder "What are all the advantages to the 64-bit version of Notepad++?".

EDIT 2: I don't think this is a duplicate of Other benefits of 64-bit OS apart from memory expansion? because I'm asking about specific benefits for this particular application. What makes this case even more curious is that, it's probably safe to say that a majority people don't need to edit more than 4GB of text at a time, and that the 64-bit version of Notepad++ has a major limitation (fewer plugins).

  • @barlop Thanks. I took a look at logging in to that site before posting here, but it appears they don't have a way to directly login. They force you to login using a third-party, most of which are social media sites. I'm not a fan of third-party logins. Am I missing something, or is that a requirement to post on their site?

  • I would assume the same slightly vague benefits as every other 64-bit program (also possible dupe)

  • One of the side benefits of running more and more 64-bit native programs is that there is a potential memory saving that will eventually happen. Currently when you have a 64 and 32 bit mix the system has to load both the 64 and 32 bit libraries that perform nearly the same function, so eventually we will reach a point where it is less and less likely to load the 32 bit version, thus saving some (probably relatively small) quantity of memory for other use.

  • @RockPaperLizard yeah but it's good to have some gmail accounts that give another name / don't give your name away. Then you'd be fine

The Show Stopper for 64-bit is: "check if all plugins you need are available for 64 bit". ref. - https://community.notepad-plus-plus.org/topic/17356/change-from-32-bit-to-64-bit

As a longtime NotePad++ user, I have always chosen 32-bit to ensure a maximum selection of Plugins. I will, of course, review the list of plugins that don't work in 64-bit the next time I install NotePad++.

  • Yes, it's surprising, given the popularity of NotePad++, that quite a few popular plugins have not been updated for many years. Jan 8 '20 at 7:03

It's the same reason as any other 64 bit vs 32 bit program; it's able to use more RAM. Therefore a 64-bit version of Notepad++ is most likely able to open and handle bigger files, than the 32-bit version.

Same question on Notepad++ forum

  • Are you serious? What is the size of a text file that a 32bit version wouldn't be able to handle? Where would text files of that size be used?

  • For the average user, it probably isn't going to matter. But I have had a few use cases, where i had to load out data/dump data from a database and also view logfiles with a lot of data, and then check for something specific in those file. I can't remember if it was 100mb or several gigabytes, I just remember that most of my sophisticated editors crashed hard, when trying to open it. I'm not sure of the max capacity of Notepad++ in 32 bit, except, that its not able to use more than around 4gb of ram. 64bit is practically unlimited ram.

  • I also believe 64-bit programs can also run under later versions WinPE which doesn't have the WOW subsystem to support 32-bit programs.

I too have had a few times where I needed to open huge log files or files created from a data extract from a database, and even Notepad++ 32 bits choked on it. In this day and age, I take the 64 bit version anytime over the 32 bit one. Myself, I don't use any plugins anyways, except for the "Compare" plugin which does what its name implies; it compares two files and marks the difference between the two. So, for me, I'll stick with the 64 bit version.

  • Interesting. How big were the log files? By "choked on it", do you mean crashed, became completely non-responsive, become laggy, or something else? Dec 2 at 6:42
