In order to move coins to an exchange like TradeOgre (which only accepts file deposits) you need to withdraw to a local wallet first, before moving them to the exchange. You can find the Qt wallets for MWC here (Windows, Mac or Linux): https://github.com/mwcproject/mwc-qt-wallet/releases
After you've received the coins in your local wallet you can create a (file) transaction to make a deposit on for example TradeOgre.
