Just read you other posts, I still say why make a lot of shortcuts in the first place - it sounds like a work-around to me when there are direct ways of doing things and adding to the QU queue!
I realize there can be a lot of ways to "skin the cat". I think of shortcuts as leveraging the operating system's natural "album" feature, with all the benefits of searching, app launching, etc. that go with it. Heck, even Microsoft has formalized the idea with Libraries in Windows 7.
Keep in mind that not all my jobs involve printing images with QU although most do. So while QU is very important to me, it isn't the control point of my workflow. For me, the control point is Windows itself and ACDSee Pro.
My main application for shortcuts is fairly simple. For every client job I do, I create a separate folder for it. In that folder, I save the relevant files for the job. Those files could include a proposal, a quote, an invoice, all files submitted by the client to me, the raw scans I have made, the final work products (PDFs, InDesign files, Illustrator files, PSD, TIFFs, etc.) However, many jobs incorporate files from previous jobs. I don't want to duplicate those files into the new job folder, but I still want them in the new job folder where it is more convenient to work with them as part of the new job. So I create shortcuts.
Where it becomes a hassle from a QU perspective is when a client asks me to print them a complete portfolio of all the scans I've done over several years. This came up recently and it involved 20 files over 2 years--not to be printed as they were originally (e.g. large on canvas for stretching) where the auto job log would be perfect, but on different paper in a different size format to fit a portfolio book. Using Windows search or ACDSee Pro, I can locate these files very efficiently and create the job folder. Getting QU to process that job folder of shortcuts is the use case.
Cheers!
