Hello Tom Brandeis,
When we encrypts a file, the AxCrypt app will create an exact duplicate copy of the encrypting file and then will the encrypt the same. Once the encryption completed, the original file will get secured deleted by the AxCrypt app.
AxCrypt used to take backup of each files when we are encrypting/decrypting and the backup will get securely deleted once the process completed successfully. So if the process was interrupted in between the process.
You can encrypt files/folder without any error(s) or corrupted. But you or any other system application(s) should not interrupt the AxCrypt app during Encryption/decryption process. If you or other third party applications will forcefully the stop the AxCrypt app during the process, then AxCrypt app will stop the process.
Still, you are facing any query, please provide detailed information about the issue and write a mail to support@axcrypt.net. We are happy to help you.
