      • Never expire  - shared links never expire, but to set an expiry date and time - turn the slider button off and and pick the expiry date. Download links are permanently inactive when they expire. 
      • Release date - use the same method to set a date and time to release your files. You can upload your files and send out the links but download links are inactive until the chosen time.
      • Security PIN- turn it on to protect your share with PIN that your user should enter while accessing files. The system will generate a random five-digit code which you should inform your recipient(s) about.

        Your generated PIN cannot be restored or reset after the share is sent. If the user forgot your shared PIN code, you need to share files again, 

      • Notify me on download - turn it on to receive a notification email when the files are downloaded.
