The image viewing software in Windows provides the image modification function ,:
This function is very useful for us who don't use PS very well. No matter where the image is changed, or when the system "auto-adjusts" and then switches to another image, the system will automatically keep a copy of the original image to a folder of the C drive user. The reason is very simple, that is, to provide an Undo function, so that users can undo the modification and restore it to the original image if they think the image is not modified properly.
One day, I performed a concentrated processing on the photos on my computer. Each photo is 3 ~ The size is 4 MB. At that time, I didn't know the system had this trick, so I found my C drive space was in a hurry in a few days. After some exploration, I learned that I had more than 1 GB of images in C: \ Users \ studyzy \ appdata \ Local \ Microsoft \ Windows photo gallery \ original images.
My photo was modified at the time. I think I can save it, so I will not want to restore the original photo in the future. The copy automatically saved by the system is useless to me and deleted directly! OK, saving 1 GB of space for my poor drive C.
