Working with filter date now..... (thanks for that idea).I've found a lot of 'old clothes' that I may still wear so meantime I am boxing them rather than deleting them, later I may decide to delete the full boxes. Its hard to let go atm. It has made a difference.
Since a few years ago, when I buy something, I always delete everything not my size and LM, pictures, demo, notes (I dont need), and empty trash before I leave. When saving in Appearance (Firestorm) I use to include everything needed to 'wear' but each item adds to the count so now, I have everyday HUDS saved at top of list and leave them out of each individual entry. For Shoes, Jewelry, Hair items, I group in Appearance and then edit out everything else (including body) so they can be 'added to existing outfit'). This has saved me heaps in the overall count. Just removing the Maitraya Hud from each saved outfit has reduced the count by 2000.
