If the file is actually damaged to this extent, no, it can’t be fixed. The data is just not there to decrypt it.
Please check the files whether those are corrupted or not using the below instructions.
But we have a feature called Check File. You can able to decrypt the corrupted AxCrypt encrypted files by navigating the menu File | Options | enable Debug from the AxCrypt app.
Also we can generate a summary of file structure, to see whether the file was encrypted with AxCrypt or not.
For the summary, you have to use the debug menu and then select the Check File menu option(Debug | Check File). Now you will be prompted to choose the files. Choose the AxCrypt encrypted file. Then AxCrypt will generate a summary of file structure.
Still, you are facing any issues, please provide more information about the issue and write a mail to firstname.lastname@example.org.
