I resigned. District won't let me transfer my files from my Google Drive.

I resigned (yes, to avoid termination. Long story). I'm on paid non-administrative leave until my resignation takes effect on 2/28. I have asked several times to spend 10-15 minutes with my school-issued laptop to export bookmarks and download folders/files from my Google Drive and from a shared Google Drive folder. I was never warned that my account would be disabled, and I have never been told why I can't download or share those folders to a personal account. Each time I've asked, I've specified that I would only do this under supervision.

Today, I was told that IT had exported all of my bookmarks and downloaded my folders from my Google Drive, but they haven't said anything to me about the shared folders.

I'd worked there for almost ten years, so there's a fair amount of stuff that I've created. Do I have any legal recourse for this? What are my options?
