Thank you for reply. On blockchain website I see the transaction in correct amount but it hasn't arrived to my ewallet yet so the reason is for sure incomplete synchronizing. However the following three questions still occur:

1. Is there a way i could synchonize for only my transaction or at least transactions that happened close to my, including my? I really don't see any reason why would I want to have saved entire history of everyone's btc usage.

2. Im planning to buy new computer soon and I would have to go through this procedure once again but is there any way to avoid it along known one - copy blocks files (from Application Data folder) from old to new computer?

3. Once synchonizing is complete, can I permanently delete any of those blocks files from first time synchronizing? Obviously up to date software data should remain after removal also but it might get outdated if I remove those block files. The reason for removing is mainly hard drive size - it really takes a lot of GBs. If the answer is ''yes'' then: how do I figure out which files can I delete so I wouldn't delete the one which contains also my transaction otherwise balance would go back to ''unknown'' (zero) one.
