Implementation Notes

A single Expert site can store up to 5,000 attachments.

A new file revision is created whenever a file with the same name is uploaded to the same page.  Use GET:files/{fileid} with the revision parameter to retrieve the file from a specified revision.

The contents.preview element only exists if a file preview is available.  Preview generation requires the file to be an image and fall within a certain size.

C# Code Sample: Retrieve File Revision Info

The following code example retrieves revision information about the file with ID 456:

Sample Code

Plug p = Plug.New("http://help.mindtouch.us/@api/deki");
p.At("users", "authenticate").WithCredentials("admin", "password").Get();
p.At("pages", "home", "files", "=myfile%252ejpg", "revisions").Get();

Sample Response from executing Code

Sample response indicating that there are two file revisions:

<files count="2">
      <file id="456" revision="1" href="http://help.mindtouch.us/@api/deki/files/456/info?revision=1">
