Thanks for all this.
A few points:
- To answer Léonie, I bought a 256Go SSD, and put the Aperture Library on it for faster sensations. With the other apps, I am almost full now. Would you think that having it on the 2To FW800 would be much detrimental, speed wise ?
- I have unchecked "New projects automatically generate previews" and no images are shared on web services.
- For the thumbnails folder, a few discoveries.
1) I could not find anything with "face" on the name. Yet I found many files with "face" on their names in the Previews folder
3) three kind of hierarchy on the thumbnails folder:
a) the names of subfolders like : /Pictures/Aperture Library.aplibrary/Thumbnail/494V5nrhS82%XLWRCasplg All these lead to files called AP.Thumbnails. They are at least a few Mo and I found one of 500Mo...
b) a single folder name "Segments" with 40 files named like "ThumbJPGSegment_23.data"
c) Folders named after the year (e.g. 2012), then inside subfolders named after the months (e.g 08) for which pictures have been shot, then the days (e.g 04) , then folders with some kind of further details as they are called something like "20120804-182743" (the first set is a recall of the date, and the second set the number of seconds ?). Inside these, new funny names like "1gbaxvSATJWVFSaPYK2XaQ" then 2 pictures files:
one small named like thumb_IMG_7140.jpg
one larger named liked thumb_IMG_7140_1024.jpg (probably for the 1024 dimension)
To be clear, the path is /Pictures/Aperture Library.aplibrary/Thumbnail/2012/08/04/20120804-173246/%eXKHTJHSG+w7byw0tcdTg/
So the AP.Thumbnails are quite mysterious and could explain the extra size of my library.
I will now run overnight the database checks and let you know !
Thanks a bunch for the help.
Cheers
