If you are trying to open a large text file with Notepad/Notepad++ and it shows the file is too large, you are in the right place to solve your issue.

Let’s dive into this article to fix the problem that Notepad cannot open large files.

Does Notepad/Notepad++ have a file size limit?

Notepad and Notepad++ can show a file size limit warning depending on your device’s memory and RAM. Most of the time, Notepad can handle a text file with a maximum size of 512MB. And

Notepad++ max file size it can handle is under 2GB.

Notepad++ uses a free and open source library known as Scintilla. It is an advanced text editing function that offers numerous features for source code editing.

It is reported that Notepad++ needs four times more memory space than the actual file size. For instance, to open a 1GB text file in Notepad++, the OS must allocate 4GB of RAM.

Therefore, sufficient RAM is needed for opening a more extensive file using Notepad++. Without enough RAM, Notepad++ will show an error called file is too large.

How to Fix Notepad/Notepad++ Cannot Open Large Files?

When trying to open a large text file using Notepad or Notepad++, they will fail as they don’t support larger files. There are several ways to fix this problem, including using a web browser or a different text editor software.

Here are the methods to open a large text file:

1. Open in a Web Browser

If you are not interested in installing additional programs to open your large text file, I suggest you try using your web browser; it is the most efficient way.

You can simply drag and drop your text file on your browser homepage. Web browsers can effortlessly handle any simple text file; the file size doesn’t matter.

Though the browser can take a couple of minutes, depending on your file size, you can go through the file context without difficulty after successfully opening the file.

2. Split the Large Files into Smaller Parts

Another great solution to this problem is splitting the large file into smaller chunks. After splitting your file into several pieces, only open one of them at a time in Notepad++. Opening multiple files can affect your computer performance.

If you want to use this method to resolve your issue, you must disable all the Notepad++ plugins that manipulate your texts. Using plugins in Notepad++ can lead your device to run slowly.

To avoid this unwanted problem, disable all Notepad++ plugins.

Here are the steps to disable Notepad++ plugins:

  • Open Notepad++.
  • Select Plugins from the menu and click on Plugins Admin. plugins-admin
  • Switch to the Installed tab and remove the corresponding plugins. remove-plugins

Syntax highlighting is also a significant feature of this program which helps users code faster. However, this great feature is also responsible for slowing down your computer. You should disable this feature if facing lag issues while opening your text file in Notepad++.

Here are the steps to disable syntax highlighting:

  • Open Notepad++.
  • Select Language > N > Normal Text. select-language
  • Disable syntax highlighting.

You can also try disabling clickable links; it will increase your document loading time.
