Explanation:

Renaming a file that is associated with an app of a group of apps means that the apps will be unable to identify itself with the file because the file name is identifying factor/link between the file and the apps associated with it.

Renaming a folder will not affect the ability of an app associated with a file stored in it because the folder merely stores the files while the files carry/store the actually data needed/associated with the apps associated with it. although while renaming a file the extension will not be changed.it is usually a bad practice renaming a file without considering the apps attached to it.
