Since updating to 10.5.3 (it may have been there before, but I didn't notice it) I have noticed that folder sizes are being inaccurately reported.
I have just come back from holiday, over 1,200 digital photo's, (≈ 2mb each), initial folder sizes correct AFAIK.
Assigning folders to day / location.
Editing by removing unwanted / poor photo's, (using GC 6.1) then PS7'ing them, I noticed that folder sizes, although reducing bore no relationship to the contents.
This happened before recently.
If I create New Folder, move contents to new folder, folder size is now correct.
Empty folder now shows discrepancy, (up to 600mb+) and when deleted master folder size is correct.
Some folders were showing 1gb+ size, transferred same files new folder now shows correct 300mb, and master folder has reduced from 3.6gb to 1.4gb.
Smaller folders <≈ 100mg seem to show correct folder size.
Any explanation for this ?
