sync.jpeg file just appeared in downloads
using safari, opened gumtree and the file sync.jpeg was downloaded to my "downloads" folder, I have moved it to the trash but I can't empty the trash as it says its in use, I have rebooted and tried again and the same "in use" comment comes up, what is it and how do I delete it.
Thanks in Advance
