When I worked at a company with the MS Suite, I used Box's auto sync on my `notes/` folder for this. Now I use Google Drive's sync, but I'm sure there's other solution for Dropbox or whatever your company uses. I knew a guy in grad school use just used `rsync` to automatically back up his folder in the same way, but I never learned set something like that up.
Haven't you ever had to create / take a new notes or edit an existing one on the go (on mobile devices)? if yes, how do/did you do that? If No, how come it is a 'No'? (added this as a comment to the original question itself.)
