I used my Nexus 7 to back up my photos from an SD card on holiday. Yesterday I deleted these using my PC via USB. Shortly afterwards, when disconnected from the PC, the top left of the screen showed that the deleted files were all back with the message "download complete" for all of them. I used Astro file manager, found the files and deleted them again. Now I get them all showing as downloaded again every 5 minutes or so, but if I search for them or try to find them now using Asrto File Manager they're not there (even if I select "show hidden files"). Any help would be much appreciated.
