I have installed the offical Ethereum Wallet from ethereum.org, it asks for creating a password to protect my account.

Is that like a BIP38 Seed that i can use to restore my wallet from another PC if my hard disk burns?

Or is it just a password to encrypt the wallet files i have on my PC, and i must backup my wallet to cold storage manually ?

This password in only for encrypt your wallet. To access the wallet in any other PC, you need the private key

So i better backup a few copies of the "keystore" folder in cold storage

You need your private key anyway, this is only for higher level of security. The password is just to make sure the person is the owner of the wallet, you can't Access your wallet with only that password, I mean.

Yes i got it.
The password is for encrypting the private key, which resides in the "keystore" subfolder inside the data folder , right?

So after i encrypt the wallet with my password, i also may want to backup the keystore subfolder to USB stick and/or cloud drive , so that if my PC burns one day i can get my backupped "keystore" folder which has the private key, and i decrypt it with my password

The pass word  in ethereum wallet is just to encrypt the wallet , it doesnt access the wallet to another pc. If you want to access the ethereum wallet , it is requiring the given private key. This given private key can only access your account. Note: it is given once you create a Ethereum wallet.
