how do I use SanDisk Ultra USB 3.0 128gb. Is there instructions anywhere

I bought a SanDisk Ultra USB 3.0 128gb. It came with no instructions on how to use . I thought can’t be that hard to find. Goggled it over 30 minutes and no trace. Looked on site ,can’t find anything . Please help and direct me to a manual or something !!!

Do note, not all files need to be saved in the vault. Many can be simply copied and pasted to the drive, outside the vault, using Windows’ file manager.
