Microsoft Edge doesn't clear cached images and files by default when it closes.
If you enable this policy, cached images and files will be deleted each time Microsoft Edge closes.
If you disable this policy, users cannot configure the cached images and files option in edge://settings/clearBrowsingDataOnClose.
If you don't configure this policy, users can choose whether cached images and files are cleared on exit.
If you disable this policy, don't enable the 'ClearBrowsingDataOnExit' (Clear browsing data when Microsoft Edge closes) policy, because they both deal with deleting data. If you configure both, the 'ClearBrowsingDataOnExit' policy takes precedence and deletes all data when Microsoft Edge closes, regardless of how you configured 'ClearCachedImagesAndFilesOnExit' (Clear cached images and files when Microsoft Edge closes).
