I created my own filing system to correspond with both the way my mind works and the designs themselves; these are all backed up ... twice ... on different USB sticks ... in case one of them quits working. I find it necessary to include a jpg image of the free designs (using free Wilcom software), but not for the bought ones (mostly Emb.Library). For those, I make a printout of each design w/color chart; these are filed in folders, drawers & file boxes ... all to correspond with my computer files. I'm not a prolific machine embroiderer and rarely use the free designs, so I just print pictures & color charts of those as I need them.
