why not use online walllet like blockchain.info to reduce the computer storage ?

Because what is the point of Bitcoin if you need to trust the third party with your bitcoins?

It is required to download the entire blockchain, otherwise, transactions and balance are outdated. There are services who provide the blockchain as a download, so you don't have to connect to nodes who are syncing slowly. After this process, you can prune the blockchain.

You can just download it with the network, there is no benefit if you don't sacrifice the security and download the chainstate as well.

I want to save and send money and recieve money i want all functions

Electrum has all of the basic functions, that are needed for sending and receiving bitcoins. It does not support multisignature and other advanced things, but those are not needed for using bitcoin on a daily basis.

so how can i transport my current wallet in bitcoin-qt to another client like electrum?

I hope that you have only balance on one address on your bitcoinwallet, if not then you have alot of copy pasting to do. Open up your bitcoin-qt and then do the following to import private key:

Open the following from bitcoin-qt: Help -> Debug window -> Console

Then unlock your wallet if it has a password:

Code:

walletpassphrase password 9999

And to export private key:

Code:

dumpprivkey yourbitcoinaddresswithbtc

Then it gives you a private key which can be imported to electrum like this: Standard wallet -> Use public or private keys and then add the private key(s) which you got from bitcoin-core. You are now able to spend the balance, but you need to only export/import the private key of the address that you have bitcoin on.

Open up electrum and make the following selections:

If you wish to send money with bitcoin-qt, yes you'll need to sync the blocks.
What do you want to do with bitcoin, are you going to spend it or save it?
For example if you want a wallet, that does not consume much of your internet, you can try Electrum which is easy to use and a light client for spending bitcoin.
Bitcoin-qt and bitcoin core is just mainly meant for developers and such, and more advanced users that want to run bitcoin full nodes.

bitcoin-qt when i run the program that will start to download blocks how can i stop that? this process will destroy my internet traffic
my questions are:
how can i stop that?
is this a necessary process? and do i need to let that download them all?

Since Bitcoin Core is not a light client, it is necessary if you want to be able to see the current state of the network.
Which means the balances of the addresses. You can't really know if you received your bitcoins or if you successfully sent them if you don't download the whole blockchain.

The download process is not as much as bandwidth intensive for very long, it takes some CPU later on.
The process will probably take around a week or more and will take around 150GB of your hard drive, maybe more.
Running a full client has it's costs and benefits. As a benefit you will get a full security and help the network by providing the security for the ones that can't afford to run a full client.
