Hey all.  I downloaded the myetherwallet.  However im having a few issues and would like if someone can answer my questions.


1.  It asks for me to put a password.  What is the point of this password?


2.  It ask me to download this keystore file.  I did this.  Then i clicked continue.  However, i cannot find this file on my laptop.  Where is this?  Any file i download should always to go my downloads folder on my windows computer.  Can someone tell me where it is?


3.  I went on the part where it says

Send Ether & Tokens


And it asks how i would like to access my wallet

Keystore File
Private Key
Mnemonic Phrase
Ledger Nano S
Trezor


I clicked on keystore file.  Then it ask to select your wallet file.  I do not see this file.  Where is it located at?  The thing was after i had downloaded the keystore file... before i clicked I agree... i tried to open the file with adobe but it says error can't open it with adobe.  But not sure where the file is right now.


4.  I then clicked on private key instead.  I then copied and pasted the private key and when i did this, it seemed to go to my wallet.  So basically assuming you don't have a ledger nano s or trezor, then its basically keystore file or private key right?  Which one of these 2 do most people use?  The thing is i don't have a problem with just copy and pasting my private key to it and accessing it this way.  But i assume keystore file is what most ppl do?


5.  I read you should backup the keystore file in many places.  How many places should you back it up besides your laptop?  The thing that confuses me is if someone has your keystore file, then that means they have access to all your wallet?  So if you put it on your external hard drive and say icloud... if someone has access to it, they have access to your wallet?  But could you encrypt that file so if anyone were to access your computer, they can't open it without a password etc?  In general im guessing you should have this copy on your laptop... a backup on an external hard drive and a backup online in case something happens to your computer/hard drive etc?  It also ask if i wanted to print the wallet.  I do not have a printer.  So if i did not print it earlier, i cannot print it later on?  How important is this printed wallet?  Im confused what is the point of this.


6.  If you just had your private key that was given to you... the long password that is generated and copied it... wouldn't that be all that is needed?  For example if you put that in your keepass and that is all that is needed?  Thus you dont even need that keystore file?  Say you backup on your password on keepass and did this in few places, well does that mean your fine?  Or you always need that keystore file?  What confuses me is it says if you lose your keystore file, you lose your wallet.  But that doesn't make sense since i just logged into my wallet with my private key?


7.  Related to the 1st question.  But what is the point of that password i created in the beginning?  Is that in case i dont have my keystore file?  Im really confused what that is.


8.  What other security things should one do with this wallet?  Also is there a feature like Electrum with bitcoin where before you send ETH... you have to put a password first before you could send the bitcoin?


Thanks all.
