When Collate Sets is selected, copies made from the images
in the set will remain in the same order specified by the set. For example,
if your set looked like this:
C:\IMAGES\DiskA
C:\IMAGES\DiskB
C:\IMAGES\DiskC
and you wanted to make 2 copies of the set, the sequence of the copies
would be DiskA, DiskB, DiskC, DiskA, DiskB, DiskC.
Using the same example as above, if Collate Sets were deactivated the sequence
of the copies would be DiskA, DiskA, DiskB, DiskB, DiskC, DiskC.
Images in a set can contain a quantity specified after the image to inform
DiskDupe that more than one copy of that image is desired. Whenever DiskDupe
sees a set with a quantity after any image, it goes into mixed quantity mode.
In this mode it will deactivate collation and set the number of copies to one.
For more information on this see Creating/Editing a Set.
If you are using a CopyBus autoloader collate operates a little differently.
See CopyBus Autoloader for more additional information.
