Great questions! I moved your post into this existing thread because I think folks looking here will be able to benefit from these questions, and because I am still getting familiar with all the features on the new forum
If the files are encrypted on one PC can they be de-crypted on another as long as you have the oDrive app, matching account, and pass phrase?
Yup! You’ve got it exactly right. odrive knows that you have an encrypted folder defined. When you install on another system, it will display the encrypted folders. When you try to get into them it will ask you for your pass phrase to decrypt. The same goes for your second question, if you need to rebuild or reinstall on a PC
My first fear reading about the word “key-chain” listed on the announcement is I don’t have a MAC which is what I associate with the word key-chain. Where is the information stored on a Windows PC?
This is a good point. We may need to add some additional language. On Mac it is stored in the keychain. On Windows it is in an encrypted registry entry.
I understand why a new folder needs to be created for the encryption to work so with that in mind can I shuttle items around to keep an existing folder structure? (I assume yes)ex. folder named “Stuff” renamed to “Stuff_temp” new “Stuff” created and encrypted. Contents of “Stuff_temp” moved into new “Stuff” that is encrypted.
Correct. The files you put into the “Stuff” folder will need to enter through the “Encryptor” root folder. Anything that passes through there will be encrypted. In your scenario you could rename Stuff to Stuff_temp, sync (download) the items you want encrypted, and then drag them into odrive\Encryptor\Stuff. You would then see all of those files in an encrypted state when looking at the Stuff folder from outside of the Encryptor entry point.
I know that some of this can be a bit confusing at first, so just let me know if you need any additional clarification.
