SanDisk Ultra 32 GB - Need to erase encrypted content

I need to erase the data from an encrypted vault so that the space can be reused.  Is there a way to do this?

Also, I know the existing password, but would like to change it to better protect the new data.  Is there a way to do that?

Thanks in advance

I can’t find any tutorial on the KB. Would be nice for inputs on this. 

" I know the existing password, but would like to change it to better protect the new data.  Is there a way to do that?"

The  Secure Access signon screen that you get when initially plugging the flash drive in gives you the option to change the password.  It’s the link right below the box where you enter the SecureAccess password.

RIGHT clicking on files in the vault gives you the option to Delete.

If you RIGHT click on the SecureAccess icon on the desktop there is a Tutorial link under the Help link one near the bottom of the window.
