Delete after 1/2 views, 5/10 minutes, 1 hour/day/week/month/year, forever, delete after not viewed within X
Don't store file type, only used for link, can use any suffix for link
Store when to delete (how many views + how long), store how many times viewed, store when uploaded (or file creation date?)
Maybe if we only support 'burn after reading' like zerobin we can use a special created_date to signify this and then never count views, or, another file, since that would interfere with 'delete after X time'
