As professor I have to organize a lot of digital documents. I have systems to do this for research and teaching and I am happy quite with these. Moreover, questions on such topics have already been asked, e.g., here or here.
However, for administrative work I regularly find myself thinking about where to store and how to name different documents like official minutes, my own notes, agendas, invitations, accompanying presentation pdfs, study regulations, law gazettes,... I have not set up a working system that I am happy with and one reason may be that, when I start to be in some committee, I do not really know in advance what kind of documents will come in. Should I arrange them by type? Should I only keep links to the place where the newest version is? Should I organize everything that is related to a certain meeting? I may add that I have a system to organize documents for hiring committees as I already know what kinds of documents are involved but that is basically it.
So my question is:
How do you organize your digital documents related to a certain administrative job?
You may answer with general guidelines but I am also interested in solutions for specific cases. I'll upvote anything that I find reasonable and check the answer as correct that helps me best.
