Why are my files not permanently deleted?
Many users mistakenly believe that once an image or file is deleted, it is impossible to recover it. Well that's not true. It is always present in the storage space of your Android phone.
When you delete an image you do not delete the image itself but only its reference in the table which organizes and classifies the files contained in your mobile. You tell Android that the memory boxes occupied by your photo can be used to store other files. You delete it from the summary that manages the files on your phone. But the photo is still physically present in the storage space of your laptop..
This is why recovery software like Recuva can recover files deleted by mistake by scanning your phone memory. Your photo will actually be deleted only when the part of the memory containing your image is reassigned to the storage of other data.
