.YENC File Extension

Encoded file that has been converted from binary to text using yEnc encoding; includes less overhead than Base64 and uuencode (.UUE) files, which allows for more efficient encoding.

The yEnc encoding method is primarily used for encoding binary files that are sent over Usenet and e-mail protocols. Therefore, yEnc files also includes a CRC checksum to ensure that the file is not corrupted during the transfer process.

yEnc files may also have a .YNC extension.
