Hello,
       I'm new here,using Tixati program.I want to know is there resume/pause options for a download.This helps alot which saves time as well as bandwidth of the users.

If I understand you correctly you want to resume a download started in different bittorrent client. If so, just open torrent file or magnet link in Tixati, wait until the transfer loading dialog appears and select path to already downloaded content. If it is a folder you should point to the parent directory, not inside the folder. Tixati will hash check the content and resume download.

The pause function is named "Stop" in Tixati, you can stop all transfers by right clicking the top menu or the tray icon and selecting Stop All Transfers. To restart just the transfers which were stopped this way right click again and select Restart All Transfers.
