Question: What are photos with FullSizeRender.jpg filename?

Apple Photos shows number of my photos to be about 26000. An external app, Investigator, and Google Photos count about 46,000. Found out many in Investigator with identical file name FullSizeRender. It seems all photos I edited and cropped have FullSizeRender photo in addition to regular photo with file name ending in .heic or .jpg. Can I delete the FullSizeRender to free up space? How can I do this quickly?

They are what are used if you access your Library via the Media Browser. And, as Larry says, if you delete them then you risk massive data loss.


If space is a premium you can move your whole library to an external disk, frformatted Mac OS Extended (Journaled).

No!


If you make any changes to the structure of content of the iPhoto library using the finder or any program other than iPhoto you will corrupt the library and lose data or photos

Which version of MacOS are you using?


The previews, mentioned by Larry and TD are called fullsizeoutput_<some cryptic number>.jpeg or fullsizeinput_<some cryptic number>.jpeg in Photos 3 on macOS 10.13 High Sierra.


On this system version I am only finding files called FullSizeRender.jpg in my user library - they are in the folder for mail attachments, notes, or message attachments.


Did you share any photos by mail or messages? Then you need to delete the corresponding messages or clear the attachments to save storage.

Leonie, I am using High Sierra. I started using Google Photos as a backup to Apple Photos, and noticed the photo count to be 46000 instead of the 26000 in Apple Photos.

Yesterday, I downloaded Investigator, which let me see the file names for the first time. Then I started to notice the many photos with the same name FullSizeRender.jpg. In Apple Photos, all of the photos I have taken, not the ones I scanned in, either using Photomyne or a regular scanner, have the name IMG plus a number .jpg or recently .heic.


Incidentally, the photos in iCloud Photo Library is about 40GB, same photos in iPhone is 17GB.


Thank you once again for your response.

I don't use Google photos, so I do not know, what happens, when I share photos to Google Photos. But for all photos I have been sharing to Mail or Messages, the edited version has been saved as "FullSizeRender.jpg".

You give no details so we can only guess

My guess is that you have requested smaller photos on the iPhone by enabling optimized photos on it to save space which of course is the reason they are smaller
