AxCrypt encrypted files are still encrypted with .axx extension only ,after deleting/uninstall the AxCrypt app from the system.
Please note: AxCrypt account and AxCrypt app are required to open/decrypt the AxCrypt encrypted files. without AxCrypt app we cannot decrypt the encrypted files.
so first install the AxCrypt app in your system, then decrypt the encrypted files, Now uninstall the AxCrypt app from the system.
Still, if you are facing any issues, please write to Support@axcrypt.net. we are happy to help you.
