I am building a website on my hard drive just using files. EX: file:///home/username/notes/main.html <a href="/home/username/folder/file.txt"></a>

I put an anchor link in the html source , and when I click on it I want it to open file.txt with gedit. I can get c files to do it , but .txt files open in Firefox.

Yes, thank you , that is the case , hence the: How to configure Firefox mime type to open text files in gedit / external editor.

Q: When we link to a file on the local filesystem , is there a 'server' sending a file type? Q: How are local files' mime-type discovered? Q: What system files does Firefox interrogate for preferred mime types? Q: What file defines the handler for .txt files?
