Bitcoin core wallet from computer to external harddisk???

[rally]

I have a question. Is it possible when you have bitcoin core on your computer (external harddisk) to install another kind of wallet as electrum or so, which needs less space as i read here on other posts.If yes, is it than possible to use the same dat.file as from your bitcoin core wallet?

Yes you can install another wallet software. No you cannot share the wallets across software.

So i can install for example 'electrum' wallet. But i cannot use my dat.file from my bitcoin core wallet, even if i delete my bitcoin core wallet?
They only possibility than is to send my BTC from my bitcoin address in bitcoin core to a new address in my electrum wallet? Is that correct?

Electrum does not use the same format as Bitcoin Core.

Yes. That is the recommended way since the seeds protect your addresses from being misplaced and simplifies the entire process. However, if you need a specific address, you can export it from Bitcoin Core and import it into Electrum.

Thanks for the clear explanation. From the moment i have some problems with my bitcoin core wallet and it keeps on going slower en slower, i think i will choose electrum. I have been reading here several topics about all kind of wallets and i have read that a lot of people find electrum a good wallet.

The synchronization of Bitcoin Core will be slower at the end since the blocks nearing the future are mostly filled and your computer will take more time to verify them. Electrum, as with most Bitcoin clients does not offer much privacy since it leaks the address to the server as compared to Bitcoin Core but it is indeed much more user friendly.
