No there is a small difference in them. Current transfers are funds transferred where no specific g+s is provided in return. For example, funds paid for insurance claims and money taken out of Australia by developing countries in the form of foreign aid.
Capital transfers however include the transfer of funds that actually involve investment in capital, and includes funds brought in by migrants and debt forgiveness. Whist some foreign aid is included here, it refers to foreign aid that is used to build infrastructure, as opposed to a simple donation of money.
I hope that explains it, I'm not fully convinced myself but there is really only a small technical difference and i doubt it is very important. Just remember that current transfers, being on the current account are irreversible, and capital transfers are reversible.
