News and Mail transfer require that a binary attachment is "encoded" before it is sent. And they are "decoded" after they have been received. Normally all this is done by your newsreader (or mail-program). You donít see it. Most donít even know it. yEnc files are formatted in a coding system that is up to 40% smaller than UUencode and Base64, and also include error checking and multipart file support. This means that posts are smaller, and take less time to download.
yEnc Format Files - How Do I Decode yEnc Files (Page 4 of 5 )
Each program varies in how you decode binary files. If you have questions on how to do this for your reader, check out the readerís website.
I use XNews, so I will show you how easy it is to decode files with it. This presumes that you have XNews configured for your Usenet provider
1. Open XNews
2. Open the folder for your server. If you have multiple servers configured, click Server (on the tool bar), and select the server.
3. Select the group you want to download the binary file.
4. Select the file to be decoded. If you want to download more than one, click the first file, and hold your Shift key, and click the last file in the series you want to download (if they are all in a row). If they arenít in a row, hold the Control key and select the files to be downloaded one by one.
5. If the file is multipart, you will see a symbol like this:
After the file name, it tells you how many parts the file is. If the symbol is dark blue, it means there is a missing part, so donít download it.
6. Click the decode button (see button in green circle above) or press the F4 key
7. When the ďSelect DirectoryĒ dialog box pops up, change the drive and folder, if desired, and then click the Decode button
8. When the file is downloading, a red bar at the bottom of the window will show you the download progress. When the download is complete, it will tell you 1 (or how ever many files you downloaded) were downloaded.
