What file extension will the encrypted file have when it is saved on the hard disk?
The file extension that this the encrypted file will have is the filename along with its extension and “.epf” is included as a postfix to the complete file name. For Example, if you are encoding a file named “Test.txt” and saving it on your Hard Disk, the encoded file name would be “Text.txt.epf”. On the other, if you are making a self-decrypting file, the file extension saved on the hard disk will have “Test.txt.exe”. which on clicking will ask for the key and then will decode it.
