Detailed Description

File names in the app's cache/incoming/ directory (copies of provider files that cannot seek).

Plain Java. A name is share- plus 32 random lower-case hex chars plus .bin: never derived from provider data (a provider name could hold path separators or collide), and recognisable strictly, so the sweep at app start deletes only files this app created there.
