The hardest thing for me right now (and traditionally) is the filing system. I used to have hanging folders bulging full of stuff. Very hard to access. I like David's idea of individual files for each item but i am still confused. I don't think my filing cabinet works without hanging folders. So if I understand correctly, I would insert one file folder into each hanging folder and label the hanging folder tab or the file folder tab. Labelling the hanging folder tab seems to make more sense (easier to read, can rearrange position, etc.) where if the file folder is labeled, inside the hanging folder it is somewhat obscured.
Also, I have lots of connected information such as receipts for purchases (warranty, etc.). Should each receipt (some of them are small) go in a separate file folder within a hanging folder labelled something like "Receipt - Printer". The Next one "Receipt- Scanner".
Also I have keep copies of all paid bills. Once again should I place each bill in a separate folder labelled "Paid Bills - Electric", "Paid Bills- Phone", "Paid Bills-Visa".
Btw, I am setting up my home not office.
