My definition of a subfolders is; Collections of similar topics/subject matter within a main topic folder, the question that this brings up is for me is, does the subfolder need to be closed or, can it remain an open subfolder. Well, as I have found out the hard way there are no regular type subfolders in Ipad/Ibooks so, what is working for me is;
Within the folder/collection is to create a numerical alphabetic system where, the numeric is the subfolder and the alphabetic is the file within the subfolder
1. Create collection/title in this case to simplify we'll use "TOOLS"
2. This involves the following sub titles/folders; Hand tools, electric tools, air tools, micro tools, electronic tools which, books or pdf's are dropped in the collection. Next is layout
1. A HAND TOOLS origin of the hammer
1. B Screwdriver
1. C Allen key
1. D Euro allen keys
2. A ELECTRIC TOOLS Drill
2. B Table saw
3. A AIR TOOLS Air gun
3. B Air drill
3. C --------
4. A MICRO TOOLS
5. A ELECTRONIC TOOLS
ETC
I know too many of you that the titles might not be exciting but, they were used to make it simplistic. Okay, once this is done and one wants to see the subfolder in an organized layout hit AUTHORS.
There is one problem that maybe someone out their can help me with, sometimes on a pdf download I will get in light grey an author, logo or something similar that will not allow that file to join my numerics. I would really like to find a way of deleting it (the grey)
Hope this helps
