Hey @Lourdes ,
When you use the SDB tool, it'll automatically download the file to your computer - this may take 10-60 seconds to complete depending on the state the device is in.
The file is generated on-demand when you use the tool, so if you're experiencing an issue and Support asks you for an OOB/SDB (Out of band / Support Data Bundle) file, make sure you do this before rebooting the device, else a lot of the logs that are helpful to support may be lost or no longer relevant.
Cheers,
Connor
