HomeTo configure options, you can click the “Option” 
icon to enter the interface below:
General
There are three tabs, General, Snapshot and Convert.
Under the “General” tab you can set preference for software update and file exist action.
When an output file has already existed in the output folder (usually because you have converted it once or more), there are three customized options.
Rename: Select to rename the present output file automatically to avoid overwriting existing file. The generated name is formed with the existing name and number.
Overwrite: Select to overwrite the existing file.
Skip: Select to skip the conversion of the file with identical name in the output folder.
Snapshot
Under the “Snapshot” tab you can set folder and format for thumbnails.
Click “Browse” button to specify location, and click the down-arrow to select format for screenshots.
Convert
CPU: You can choose how many cores you need to use for converting.
Process: Here you can set the maximum simultaneous running process.
