I recently blogged about modern retention labels and how you can create labels, publish them to sites, and then have them available for users to apply to files. This assumes that end users apply the label manually to every file. However, in reality, this is not sometimes practical, especially if you are dealing with hundreds or thousands of files. Luckily, we have a way to apply retention labels to libraries and folders, thus automatically tagging and setting retention for the files inside.
