.YNC File Extension
File TypeyEnc Encoded File
What is a YNC file?
File encoded from a binary to a text format using the yEnc encoding method; similar to a standard US-ASCII encoded file, but significantly reduces the file overhead by using 8-bit Extended ASCII encoding; also includes a CRC checksum for verifying the integrity of the file.
The yEnc format was designed for encoding large binary files that are sent over Usenet and e-mail protocols, which require binary data to be encoded before being transferred.
