Okay, ladies. I've been reading all these wonderful and helpful posts about sorting and saving your designs. I have to tell y'all that my feeling are getting hurt.
About 8 years ago I personally designed a program for organizing all my embroidery designs. I designed it for my own needs and every single need or want that I could possibly think of that you might have.
First of all, you wimpy embroiderers with only as many designs as will fit on a flash drive, well, I can fit all 70,000 of mine on 6 flash drives or 2 DVDs. Now all those designs amount to less that 6 GB, a negligible amount of space on my computer, so I keep them there. I also have them backed up (automatically every night at 11 PM) on an external hard drive, along with all of my photographs, all of my digital scrapbooking elements (which are what reallly hog to space) and my My Documents folder. My digital scrapbooking designs and my photographs are also backed up on a portable external hard drive and my embroidery designs and MY Documents on another, smaller, portable external hard drive that I carry with my laptop. I also burn all of these to DVDs a couple of times a year, 2 sets, one set for the safe in the house and the other set for our safe deposit box at the bank. I'm a huge advocate of backing up often and in several ways.
My embroidery designs are sorted on my had drive into several folders, Original Designs, Purchased (commercial) Designs, Downloaded Designs and, of course, all the Free Designs from my web site. Within the Commercial designs folder are folders for each of the companies from which I've purchased designs, Dakota, Amazing Designs, Embroidery Library, Brother, OESD, etc. So you can see that I'm fairly well organized. BUT when I want to find something I look for it in Catalog XPress, the program I designed for us. You see, for example, I have designs of cats in several Amazing Designs sets, several OESD sets and at least 2 Brother sets. But all of the cats are in Catalog XPress in the Cats folder. When I want to stitch a cat, instead of having to look through all of those folders, I look in only 1 place. If I have a design with a cat and a dog it will be in both the Cats and Dogs category. If the cat and dog are wearing hats the design will be in the Cats section, the Dogs section and in the hats section. If the hats are red, white and blue the design will also be in the Patriotic section. And, to carry this even further, if the cat and dog wearing red, white and blue hats are riding in a car the design will also be in the transportation category, in the Cars sub-category. You could, of course, do this on your computer by putting copies of the design in folders with those names, but then you'd have multiple copies of the design. With Catalog XPress I have only the one original design.
You say that all your designs are on flash drives aor CDs and Catalog XPress doesn't know where they are? Yes, Catalog XPress has the memory of an elephant. Or at least the memory of a much younger woman than I am. When you click on a design that says "Not Found" look at the address bar at the top of the screen and Catalog XSPress will tell you exactly where to find the design. You complain that all you can see are wimpy little cartoon pictures of the designs (on the other hand, in Windows Explorer you don't have any pictures at all). Again, not so. Right click on the design in the preview window and choose 3D view. Now the design appears in all its stitch-filled glory. Picture not big enough? Grab the edges and pull it bigger. Sorting is the main function of Catalog XPress, but not the only one. The programmers who helped me develop Catalog XPress thought of lots of things that didn't even occur to me or that I didn't think were even possible.
So, all this talk about sorting and storing designs with no one mentioning my baby, well, my feelings are hurt . . .
I'll have a name tag project in my blog this week, so so lookl for that if you're still wondering how you're going to make your name tag for our luncheon. I'll probably copy and paste some of the above rant about Catalog XPress in there, too.
Okay, I'm finished now . . .
