I also got this “…’ is not an AxCrypt file.”
I got this for couple files when I decrypted them. Now I have this .axx file and same file decrypted. So, it seems that decrypting worked. However, it is weird that not I have .axx copy of file. Also, files size for this .axx file is 0 bytes.
Can I delete this .axx files? Or should I keep them? Is there something still to be fixed?
