Usually when I use Preview, it is when I see a .jpg
or .png
and I double click on the file to take a look at the file, but sometimes Preview will open up all the .pdf
and .png
I opened previously, possibly taking up a couple hundred of MB and opening 7 or 8 windows.
So it is a case I hope an app will not open all previously opened files. I know it can be done by clicking File, pressing Option, and then choosing Close All, but is there a way to tell an app not to open all previously open files such as for the case of Preview?
