Enabling the AttachFile action

The AttachFile action lets a page have multiple attached files. Since file uploads could be abused for DoS (Denial of Service) attacks, AttachFile is an action that can be disabled by the wiki administrator. See Configuration of MoinMoin for details.

Creating attachments

To create a new attachment, you can either add an attachment link to any page (see below on how to do that), or click on the AttachFile link at the bottom of the page. In the first case, you will see an Upload new attachment link after saving the page. Clicking on it will lead you to the upload page, just like directly clicking on the AttachFile link.

The upload form consist of two fields. In addition to the file input there is an optional field (Rename to), used to give the file a different name than on your own computer.

An upload will never overwrite an existing file. If there is a name conflict, you have to rename the file that you want to upload. Otherwise, if "Rename to" is left blank, the original filename will be used.

Existing attachments may be viewed, downloaded, or removed, depending on the configuration of the wiki and the access rights of the user. For example, an attachment cannot be deleted if the user doesn't have the delete permission on the particular page.

Any upload or deletion of attachments is reflected on RecentChanges and thus subject to peer review. Unlike page changes, there is no history though, so keep a local copy of files so you can revert possible vandalism.

Listing and information about attachments

Two macros are defined which give information about attachments on a page. The [[AttachInfo]] macro gives a short sentence about any attachments:

There are 8 attachment(s) stored for this page.

The [[AttachList]] macro lists files attached to a page: --> -->
