Often, Stellar Photo Recovery can recover permanently deleted data. But it depends how the files were deleted. The most common type of deleting data in cameras and other devices doesn't actually wipe the data sector by sector. It's sometimes referred to as a quick format. With a quick format, when files are deleted, they aren't immediately removed from the storage device, but their space is marked as available for reuse. Unless the space has been overwritten, Stellar Photo Recovery can often still recover that data. However, some cameras, devices, and all computers also offer a more thorough method of formatting memory cards that's often called a full format. That function, which takes longer, goes through and wipes the data sector by sector. Data that has been wiped that way often proves impossible to recover.
