.UUE File

The uue file extension seems to be mainly used for encoded ASCII files for binary attachments.

Uuencoding is a form of binary-to-text encoding that originated in the Unix program uuencode, for encoding binary data for transmission over the uucp mail system.

The name uuencoding is derived from "Unix-to-Unix encoding". Since uucp converted characters between various computers' character sets, uuencode was used to convert the data to fairly common characters that were unlikely to be "translated" and thereby destroy the file. The program uudecode reverses the effect of uuencode, recreating the original binary file exactly.

uuencode/decode became popular for sending binary files by e-mail and posting to usenet newsgroups, etc. It has now been largely replaced by MIME and yEnc. With MIME, files that might have been uuencoded are transferred with base64 encoding.

MIME types:
text/x-uuencode
application/uue

Files with uue file extension can be usually encountered as various ASCII based attachments, especially on UNIX platform.
