What is a DSY file?

A DSY file is a video file used by Besta devices, such as the Besta Electronic Dictionary. It is similar to a Flash (.SWF) file but saved in the proprietary Besta format only recognized by Besta hardware. DSY files typically store short clips or animations.

More Information

Besta developed the DSY video format specifically for their devices, most notably the Besta Electronic Dictionary. You may encounter a DSY video playing games or watching educational videos when using the device.

Besta devices come with DSY video files pre-installed, but you may download DSY files from the Besta site and transfer them to the device. However, Besta no longer supports the format.

How to open a DSY file

You can only open a DSY file with Besta hardware that supports the DSY format, most notably Electronic Dictionary.
