The decrypted file with the original extension will be extracted in the same folder as the encrypted file.

Instead of encrypting the original file, you can encrypt a copy of the original file by selecting AxCrypt → Encrypt a copy. This would leave the original file as it is, but also creates its encrypted copy in the same folder. Similarly, if you select AxCrypt → Encrypt copy to .EXE, then it will create an encrypted executable file in the same folder as the original file. The encrypted EXE is great option if you want to send the encrypted file to a friend who does not have AxCrypt installed. Your friend can just double-click on the encrypted EXE file and type in passphrase to decrypt it without the need of installing the AxCrypt on his/her system.

You can also randomize the file name of the encrypted files, so nobody can guess what the original file was. Just right-click on an encrypted file and choose AxCrypt → Rename. The selected files will be given random names. Do not worry, when you decrypt these random named files, you will get the original filenames back because AxCrypt stores the original filenames inside the encrypted files themselves.
