So - we have some pretty good technology experts here, so I thought I'd reach out.

My wife is a teacher, and I recently got her a laptop so she can work on files while at work. She also does a lot of work at her desktop here at home.

Here's my question:

Is there a program out there that automatically updates a FOLDER when documents are changed? I've looked at OneDrive, Dropbox and the like, but I don't know if the files within the folder itself is updated when changes are made. She doesn't want to save every document to the cloud because sometimes she doesn't have a good internet connection, but if there's an easy solution to that, we'd entertain it.

This might require additional description - just let me know what questions I can answer.

PS - she uses Office 365.
