If your goal is to keep an USB stick encrypted, the SanDisk software may well work fine. (Although such bundled softwares have often proven to be less secure than advertised). Here VeraCrypt can do the same job as well. And, depending on the user case, so can AxCrypt especially if you use the “Secured Folder” feature to easily keep the separate files in the folder encrypted, and if you wish to you can use the “Anonymous Rename” feature to hide the actual file names as well.
Try the various options and use what is the best fit for you!
