Restoration of BitCoin Wallet

[AleksandarTheConfused]

Hello to all the forum users,
Excuse my for my incompetence, please let me ask you a question.
A colleague of mine, who is really busy, used a BitCoin Wallet 2-3 years ago in which he had 50-60 coins, which he mined. He has a backed-up wallet file from then, but the issue he says is that the synchronization with all the transactions and what not (this part is not really clear to me) would take his computer from 2-3 weeks, having it non-stop working. The question I am trying to ask here is, is there an alternate, faster way to get his bitcoins back?

Does your friend have the secret key or just the wallet file?

Sorry, by secret, I assume you mean "private key" and the answer is yes, I think he has it.

If that's the case, create a wallet using a service that doesn't require the entire block chain to be downloaded and import the private key into that other wallet.

Are those services safe? Can you suggest one, please? Thank you so much in advance, you have been of great help!

I won't suggest one over the other so as not to be seen as biased, have a look at Bitcoin Forum > Bitcoin > Development & Technical Discussion > Alternative clients (Moderators: gmaxwell, achow101)

which can be found here: https://bitcointalk.org/index.php?board=37.0

He can use a 'lite' wallet program (like Electrum) and import his private key. This will only take a few minutes to sync, not weeks.
