It sounds like you are using an Encryptor folder, but it is unclear how you have separated it from the default odrive folder. Are you using a symlink/junction?
Are you using a single Encryptor folder, or creating and then removing Encryptor folders as they finish sync?
I would say you don't want to delete the items in Encryptor. This is a sync engine, after all, and you wouldn't want the deletes to be synced back to the cloud, which would delete the remote data. odrive has the odrive "trash" concept to prevent inadvertent deletes, but the trash will start filling up and could create increasing overhead. Plus, when you delete the items locally, they will be removed from the local view, even though they will still exist in the cloud until you've emptied the odrive trash. I have a feeling this may a major component in you asking this question in the first place . Do you see many items listed in the trash from the odrive tray menu?

Unsync would be a better option here, especially if you can unsync entire folders of content as you pushing things up via your temp folder.

I know I'm throwing out a lot of terms and concepts that you may not have fully explored yet, so it may be best if you can give me the lay of the land, so to speak, on how this is setup. The way you describe it may not be the best way to go about this, but I also might not fully understand the setup.
