Is there any way I can recover my corrupted photos and videos after I by mistake deleted the emulated folder in root???

To free up space I deleted the emulated folder using a androzip app in root.After that my photos and videos have been replaced with a black photo of a portrait and an exclamation mark (corrupted photo). Since technically the photos and videos are still there is there any way i can recover them/uncorrupt them? PS: Yes I am an idiot :P
