File Attachments

Changed:

Each topic can have files attached to it. This is similar to an e-mail attachment. Just use your browser to upload or download a file. Attachments are stored under revision control - no upload is lost.

What Are Attachments Good For?

Added:
>
>
File Attachments can be used to create powerful groupware solutions - file sharing, document management - and for speedy Web authoring.
 

Document Management System

Changed:
<
<
  • document management system: distribution, revision
>
>
  • You can use Attachments to store and retrieve documents (in any format, with associated graphics, and other media files); attach documents to specific TWiki topics; collaborate on documents with full revision control; distribute documents on a need-to-know basis using; create a central reference library that's easy to access and manage by an entire user group.
 

File Sharing

Changed:
<
<
  • share files: applications, data files; recommended for light use
>
>
  • For file sharing, FileAttachments on a series of topics can be used to quickly create a well-documented, categorized digital download center for all types of files: documents; graphics and other media; drivers and patches; applications; anything you can safely upload!

Web Authoring

 
Changed:
<
<
  • on-site use: linking to graphics, docs
>
>
  • Through your Web browser, you can easily upload graphics (or sound files, or anything else you want to embed on a page) and place them anywhere in on a single page, or for use across a web, or site-wide.
    • NOTE: You can also add graphics - any files - directly, typically by FTP upload. This requires server access, and may be more convenient if a large number of files, or a particular directory location, is required. These files can't be managed using browser-based Attachment controls.
 

Uploading Files

Changed:
<
<
  • To upload: Click on the Attach link at the bottom of each page. A form is shown where you can browse for a file and upload it. The uploaded file will show up in the File Attachment table.
  • Files of any type can be uploaded. Some files that might impose a security risk are renamed, i.e. *.php files are renamed to *.php.txt.

  • The previous upload path is retained for convenience. In case you make some changes to the local file and want to upload it again you can copy the previous upload path into the Local file field.

      • %PUBURL%/Otherweb/OtherTopic/Sample.txt (for adifferent web)
 
  • Attached HTML files and text files can be inlined in a topic. Example:

>
>
    1. Attach file: Sample.txt
