How long does it take to read the file using Fiji, after it has been
copied to the Desktop?  That would help us to know if this is strictly
due to the network file system, or if the procedure for reading the file
is too slow.

It would also be useful to know which options you have selected in the
"Bio-Formats Import Options" window.

Having more folders can cause subtle performance degradation, but
typically not as much as you describe.  If you open the file in Folder7
twice in a row, does it take 12 minutes both times?
