Imap with Gmail question

[Scam]

If i'm using Thunderbird to view my messages, what's the difference between deleting a message i've just read (in my inbox), or moving it to the 'All Mail' folder?

When i used POP (not Gmail-hosted) i used to only save a select few messages that were of interest, and delete the rest. With Gmail, i started moving my 'keepers' to 'All Mail' and deleted the rest as normal.. but i think it's now the same thing?

Its the same thing AFAIK, to delete a message you need to move it to the trash folder, it's then deleted within 30 days i think, unless you delete it from that folder. It works something like that anyway.
