Only systems that come equipped with 16GB of RAM and more can properly run that task but the OS may often deny it, as explained above. Opening a 2GB file in Notepad++ requires 8GB of memory. When your operating system receives the memory allocation request from Notepad++, it may deny it in order to preserve system resources. In order to provide rich text viewing, alongside code folding, syntax highlighting, and more, Notepad++ requires four times more memory than the file size.įor example, if you want to open a 300MB file, the program will use around 1,200MB of memory.
