File - Edit: File Properties. Description This view allows you to edit File properties. Form Elements 'Title' -- The optional title of the File. 'Content type' -- The content type of the file. Zope will try to guess an appropriate content type when you upload a File. 'Precondition' -- Allows you to specify a precondition for the File. A precondition is a method or document which is executed before the File is viewed or downloaded. If the precondition raises an exception then the File cannot be viewed. 'File Content' -- If the content of the file object is text-based and small enough to be edited with a Web form, a textarea containing the content of the file will be displayed. You can make changes to the content in this text area and click the 'Save Changes' button to update the file content. 'Last Modified' -- The time that the object was last changed. This is only displayed if the file data is non-text or too large to be edited with a Web form. 'File Size' -- The size (in bytes) of the image data. This is only displayed if the file data is not text or too large to be edited with a Web form. 'File Data' -- The file to upload. Use the 'Browse...' button to select a local file.
