I am having the same problem. I have photos on a flash drive. thousands of them, as I try to pick a bunch of them at the same time, using ctrl then pick the ones that I want (shift would pick all in a row) it automatically starts creating copies of some of
those jpg files and naming them copy (2) 3 etc. and the file name of the photo.

==============================
I suspect your copies are being created
as follows:
Hold your Ctrl key and select several files...
Place your pointer on the selected group
(still holding the ctrl key) and left click / drag
the group even just the slightest bit...now
release the mouse button. (this happens by
accident when rapidly selecting files)
The 'Copy of xxx.jpg' duplicates will appear.
Changing your folder options from Double
Click to Single Click should prevent the
accidental copies.
With single click selected...all you have to
do is a mouse over...no click is required to
select (highlight) a file.
One mouse over selects a file and a second
mouse over deselects the file. No clicking
required. Just hold your control or shift key
and mouse over /select all the files you want.
Windows 7 - Open files and folders with a single click:
Start button / Control Panel / Appearance and
Personalization / Folder Options / General tab...
Left click..."Single-click to open an item (point to select)" / OK
===
There's also a Registry Hack that can increase
the number of pixels the pointer can move before
releasing the button will create the copies. The
instructions I have are for XP and Vista and I'm
not positive it works for Win 7.
