You can keep the executable anywhere on your computer or on a memory device and run it when necessary.
A major advantage with VobSub Ripper is its wizard-type interface, which is friendly with all user categories.
All you need to do is select the IFO title of the DVD and choose the destination folder where the subtitle will be saved.
Advanced options of this utility include selecting the program chain, selecting the language stream and the VOB IDs, and enabling forced subtitles.
The ripping operation is fast and straightforward and the amount of system resources needed by VobSub Ripper is low.
On the other hand, the application has not been developed anymore for a long time and it lacks today’s advanced features.
VobSub Ripper is portable and it doesn’t come with an installation pack.
