How do I get the real file path of an image? When I look at an image on my phone in the gallery app, it tells me (under details) the path is /phone/Pictures/Messages/imagename.jpg. My native file browser can find this image in that path. A third party file browsing app tells me it's in /storage/emulated/0/Pictures/Messages/imagename.jpg. My computer can find neither of those directories on my phone or SD card, and a search of both for the image name reveals nothing. I'd like to move the images to my phone. How do I find the real file path of this file?
The second one is the technically correct path. The first one, /phone/..., is just the Gallery app simplifying the display and telling you that the folder is in phone storage (instead of external storage).

When connected to the PC using MTP, the root folder is /storage/emulated/0/ (you only see the contents under it), so you should be looking for the part of the path after it, which is Pictures/Messages/imagename.jpg.
