Have been keeping a very important doc that needs daily updates in Dropbox. Just purchased an app (non Microsoft) which enables me to edit Office docs so I can carry out the necessary edits on this doc, but I don't want to give the app access to my Dropbox. Thought it might be a better idea to keep this single doc in a separate folder on my desktop and edit it from there. Is this the safest way to go about it? Would I be giving the app permission to look at anything that could be risky?
