I have over 3100 on my master list alone. That doesn't include ones I have only in apple claris works from my old ibook.
I have three main categories of folders: Master list (just creating it the last couple of weeks, it's still not complete from what I have saved but it's very comprehensive now). Then I have a folder that contains the folders of every single author I have a story for, and each author has a copy of their story in their story folder. The third section is by pairing. Major pairing, major character plus 'other', and major character where there is no pairing. Every story on the master list goes also into one of those 'pairing' folders. So there are three places a story might be. I tried doing a database list but it got too complex and I lost interest. I don't have any list for categories other than pairing. My new 'reading now' folder is for stories I am actually reading. I have a WIP folder for stories I am trying to read but am waiting for an update to continue. And I have a new folder (to keep my reading now folder from getting ridiculous like it did before) of stories I notice that I really want to read soon but can't right now. I have a huge computer memory so I don't care if I have multiple copies. But with over 3100 separate stories on the one list alone, you can see how it multiplies quite a bit in my system. But my system is quick, I don't have to type into a database to find stuff or type up any separate lists.
I saved stories starting long ago because a) I like to format and pick colors and fonts that are easier for my eyes to read and b) they disappear!! before I'm done with them. As this forum proves. Especially now, the show being off the air so long and people losing interest, losing jobs and having neither money nor time to keep up their sites and archives. I have found some 'now gone' stories thru back doors thankfully. Like award sites where if you click on the story you get linked to sites that 'no longer exist' and to stories that have been 'taken down'. I'm not sure how but that works.
Long post, sorry for all the words. I'm not supposed to type so much today.
