So, I am uploading some files to my account to free up space on the HD. How do I know when it is "safe" to delete those files from the original computer? Should I be watching DropBox and if it is still syncing? Or should watch for the circular "upload-status" icon to disappear in BoxCryptor? I really do not know and this would be a huge help. I always upload files and then don't know when it's safe to delete them and then forget to delete them, which kind of defeats the entire purpose of what I am trying to do... which is free up space.
