why not use Storage Folders for all inactive emails?

Having followed the good advice of Shawn on a nearby recent thread, I successfully restored lots of 'orphan' messages, one by one. Now I have the tedious task of moving them back to the folders they started in, from the Storage Folders to the account-related ones. It is tedious because you have to manually create each individual folder in the target area.
But why bother? At least for relatively inactive files? That is, what is the operational difference between Storage Folders and the account-related ones?
I cannot find a simple description of that elsewhere.

There is one difference between the Storage area folders and those under a POP3 account: If you ever want to delete the POP3 account all it's subfolders and the contents will dissappear with it. I've set up my WLM to look like Outlook Express by having all mail forwarded to a single POP3 account. I then created sub-folders under it to sort messages into. However, I must remember to move all the important sub-folders over to the storage area before I delete the account.

To roncerr: thanks for that. I have my own POP folders set up the same way. But I guess you answered my question, indirectly: there is no reason not to move inactive emails into Storage Folders, to avoid future errors like the one you refer to.
Thank you. I have more serious trouble with my POP3 and WLM, but that's a new thread I think.
