Hi, I was using an app on my phone to transfer my pics to my laptop via Wifi. One of the folders was 19 GB. The zip had stopped downloading after 9 GB. I attempted to extract it, but the folder was said to be invalid and empty.. yet when I would run the cursor over it, it said the file size is 9.39 GB. What is going on, and is there a way to fix this? I would greatly appreciate any help!
