Docker compose creating volume from windows to linux?

Hi,
Thank you for your help I have opened some docs about bind volumes and that was exactly what I needed for.
However there is not much informations on docker windows, I’ve seen that the path of the source is written as it is on windows

C:\Users\fil1\my file2\myfile_3

but you used

/c/Users/ffil1/my file2/myfile

, which one is the correct format ? and does it allows spaces on the name ?
