How to turn off File Browser prompt?

Question

Is there a way to turn off this feature?

It is very slow and totally unnecessary for me. I have tried to look for a setting in preferences but I couldn't find the right box to untick.

Answer 1

If you set the (documented) cell option

CodeAssistOptions -> {"FileCompleteEnable" -> False}

then the File Browser popup won't appear when editing the cell. Alternatively, you can set the option for an entire notebook:

SetOptions[EvaluationNotebook[],
 CodeAssistOptions -> {"FileCompleteEnable" -> False}]

Finally, you could change the style of "Input" cells by using a custom stylesheet or editing a private stylesheet for the notebook.
