Hello P Towner,
AxCrypt performs as much as faster based on the user’s system configuration and the number of files, its size. When encrypting bulk amount of files or larger files, AxCrypt will take some more time to finish the encryption/decryption.
We are going to start working on the App optimization issues. So users will get the optimized version of the AxCrypt app in near future.
If the above does not help,Please provide more information about the issue and write a mail to email@example.com .
You can also send the complete error report to troubleshoot the issue. Please follow the detailed instructions to take the complete error report: https://www.axcrypt.net/blog/send-complete-error-report/ . so that we will try to troubleshoot the same as soon as possible.
