The Android version of AxCrypt currently does not facilitate bulk decryption of multiple files within a folder in a single operation. This is due to restricting additional app permissions. Each file must be decrypted individually through the app. Although, we understand that decrypting files one by one can be time-consuming, especially when handling multiple files. While this limitation is in place to maintain strong security controls and app permissions on mobile devices, we appreciate your feedback and will definitely put it for future consideration. In the meantime, for bulk operations, we recommend using the desktop version of AxCrypt, which offers more flexibility for managing multiple files at once.
