Retrieving Microsoft's Spotlight images.
The spotlight.cmd command is scheduled to run once a day, using Windows' Task
Scheduler. It can also be run directly here. It writes image files and other
information in %localappdata%\spot.
The log.txt file has one entry for each run. When a new snapshot is written,
the image files themselves are written under %localappdata%\spot\img\<date>,
and a text version of the snapshot is written in
%localappdata%\spot\snap_<date>.txt.
Collecting images from the snapshots is done with copy_images.py (this
requires the activation of the virtualenv). It copies image files to the
master sub-directory. This must then be manually copied off-site.
