Configure Attachments...

Opens a dialog box allowing you configure options related to attachments.

Article Split Length / Estimated Number of Lines

This option determines how large an individual posting is allowed to grow before it is split into a multi-part posting. Posting extremely large files as a single Usenet post will break some news sites and is considered good "netiquette" to break the post into multiple parts. If you are posting with large attachments it is recommended you set this value to less than 500,000 however you can disable article-splitting by setting this option to None (not recommended). Making this value too small can make attachments split into many hundereds of posts, which is also considered bad "netiquette". Conversion between Lines and Bytes is approximate, and is based on the encoding format you use.

Create individual posts for each attachment

Most attached files are now started in their own article, unless the files are small or part of a particular message. If you intend to post many files it is recommended this option be checked.

Default Encoding Type

This checkbox sets the default for attachments, which you can then override in the Manage Attachments dialog.
If you use the yEnc coding format, MIME headers are disabled. If you use Base64 encoding MIME headers are always enabled.

Custom Encoding Table

Specifies a custom table of exactly 64 unique characters for use with the Custom Encoding Type. Custom encoding is rarely seen anymore. See Custom Encoding Tables

Subject Line Template For Multi-Part Send

The Subject Line Template allows you to customize a detailed subject line for a multi-part send. A text string can be entered and interspersed with the symbols %s, %f, %p or %t:

%s in the template will be replaced with original subject line

%f will insert the filename of an attachment (or the words "N attachments" where N is a number greater than one if not using Individual Posts)

%p is the part number of a multi-part message

%0p is the part number of a multi-part message, prepended with zeros to match the length of the total number of parts

%t is the total number of parts transmitted.

%b is the number of bytes in the attachment.

%k is the number of Kbytes in the attachment.

use %% in the template if you need a literal percent sign

WinVN defaults to the following Subject Template:

%s - %f (%0p/%t)

For the 5th part of a 12 part send with an original subject called "Testing " and an attached file called "aconfig.bmp", this would produce the subject line: "Testing - aconfig.bmp [05/12].

If you do NOT have "Create individual posts for each attachment" checked you get the following:

For the 1st part of a 7 part send, with an original subject of "Hello", and 4 attachments, this would produce the subject line: "Hello - 4 attachments (1/7)"

If you DO have "Create individual posts for each attachment" checked you get the following:

For the 1st part of a 7 part send, with an original subject of "Hello", and 4 attachments, this would produce the subject line: "Hello - attachment1.ext (1/1)"
