Now, click on the New icon. The installation wizard will pop back up. This time, create another encrypted folder for a different cloud service or offline folder than you did originally. For example, I created an encrypted folder in my Dropbox account to complement the BoxCryptor folder I'd already created in my SkyDrive one. Finish up the creation process as you did before, creating a password and selecting a virtual drive designation. Advanced options will pop up during the process, but you don't have to worry about those unless you're curious about the software's niche uses. Bonus: You don't have to reboot the second (or third, or fourth, or...x) time you create a BoxCryptor folder.
When you're done, a BoxCryptor.bc folder appears in the new location, and a BoxCryptor virtual drive appears on your computer, just as before. Utilize this second encrypted folder the same way you did your first one, by adding and removing files via the virtual drive, not the BoxCryptor.bc folder itself.
But what if you need to access or add a file in the encrypted folder you created the first time around? That virtual drive--but not the folder itself--disappeared when you removed it from the BoxCryptor list to create your second encrypted folder. Fear not: It's easy to connect back to your previously created BoxCryptor folders.
First, Remove your current virtual drive in the Advanced Mode as you did before, but this time, click Add rather than New when you're done. You'll be asked to choose the location of a BoxCryptor folder; select your originally created BoxCryptor.bc destination. (In SkyDrive, in my case.) Next, choose a letter for the virtual drive you're creating, ignore the advanced options, and enter your password for the encrypted folder when prompted. Bam! A virtual drive connected to your original BoxCryptor folder appears on your computer, allowing you to encrypt and decrypt your files to your heart's content.
Deselecting and reactivating virtual drives in order to jump between multiple encrypted folders gets the job done, but running through the reactivation process over and over again gets very tedious if you bounce between multiple services on a regular basis. If you want to maintain several encrypted folders and plan on using them often, I highly recommend upgrading to the $40 Unlimited Personal license--both to cut back on the headache and to support the developers of this excellent piece of software.
