Step 1
If you no longer have (or never had) the original .torrent file, download it from the original poster. In the 'File Download' applet that appears when you click on the .torrent attachment, you can choose between 'Run' and 'Save'. Choose 'Save', and navigate to the directory where data file(s) are. (The data files are the actual videos and/or picture files). When the download is complete (usually takes 1 or 2 seconds, even with a slow internet connection), Choose 'Open Folder'.
Step 2
Right-click on the .torrent file, and choose 'Properties' from the sub-menu. Highlight the value in the 'location' field (it usually scrolls, start on the left and pull your mouse hard to the right), right-click, and choose 'copy'. Close the 'Properties' applet.
Step 3
If you already have the .torrent file extension is associated with your torrent client software, click on the .torrent file.
Otherwise, right click on the .torrent file, and choose 'Open with ...' and choose or navigate to you torrent client software. (If see a check box that says something to the effect of 'Always use the selected program to open this kind of file', check it).
An 'Add New Torrent' applet appears. In the 'Save As' text box, replace whatever value is in there with the 'location' value that you copied from step 2 (right-click and paste). Click 'Okay'. Edit - The file names that your torrent client is looking for must match the file names of the data files that you pointed to.
