Hello again,

The problem is still there, if I save a picture from facebook, the file is stored on my internal memory.
It is visible by every application and through usb connection but as soon as I move it with F-stop to a folder on my Sd card the file becomes only visible by the F-stop app and not by other apps nor usb connection.
The problem is solved by :
– a reboot
– running the media scanner app (https://play.google.com/store/apps/details?id=info.superkiki.mediascanner)
Should F-stop not force a media scan after it moves a file???
