Where Do Deleted Photos And Videos From Cellphones Go?
JAKARTA - The memory capacity on a smartphone is not always enough to store hundreds of photos. Sometimes, we need to sort out old photos and videos for deletion so they don't take up the cellphone storage space.
So where do the deleted photos or videos from the cellphone go? The answer, it's still in the internal memory storage (ROM) and SD Card on the cellphone.
It's just that to see deleted photos or videos again, we have to enter the Android file system. The reason is, the photos have turned into pieces of data or bytes in binary form.
Like a word, internal memory is a large housing complex and its contents are houses which will be filled by data bytes. In every housing gate, of course there is an address book, so when there is a new file, the data bytes will be placed into the empty houses based on the address book.
So when, you delete a photo or video, the data does not immediately remove the bytes stored in the internal memory. But keep in mind, the existence of the data bytes is not permanent and will be lost if it has been overwritten with a new file.
Then how do you get all the photos and data that are stored can be completely erased? There is a mechanism called the shredding file.
Through this mechanism, the data bytes or code binaries from the photo and video files are completely removed from the internal memory location. But by default this shredding file is not used by any operating system, both Linux Windows and Android because it requires additional tools such as software and flash memory.
