What is a .nim file?
A .nim file is a nim source code. Its registered MIME type is text/x-nim, which places it in the text family of formats.
Technically it is a specialised form of text/plain (the .asc format), so tools that understand that format can often read at least part of it.
NIM is a text-based format: the contents are readable characters, so any text editor can open it, and it compresses well.

How to open NIM files
| Windows | NIM files are plain text, so Notepad opens them: right-click the file, choose Open with, then Notepad. Notepad++ and VS Code are free and show long files more comfortably. |
|---|---|
| Mac | TextEdit opens plain text files. For code or data files, a free editor such as BBEdit or VS Code keeps the formatting intact. |
| iPhone and iPad | Save the file to the Files app and tap it; iOS previews most plain text. Or drop it on the viewer above, which shows the text right in the browser. |
| Android | Most file manager apps open plain text files in a built-in viewer. The viewer above also works in Chrome. |
Can you convert a .nim file?
TapToConvert does not convert NIM files. The usual route is to open the file in the program that made it and use its Export or Save as option.
