Is there any other common factor linking the folders you have this problem with? Do they all contain files of a particular type, just for example?
Word used to be a real pig for this sort of symptom but that was many, many versions ago - Word 2003, I think. It used to forget to delete its own temporary files when you closed a file or even closed Word completely & it kept a lock on those temp files as if you were still editing.
