I am using the File field type to allow a content editor to upload a new file, or select an existing file.

I wish to restrict where a file can be chosen from, so I have set the datasource of the field to a folder in my Media Library:

DataSource=/sitecore/Media Library/Images/

Now, when I click Open File on a content item, I get the error:

How can I specify a 'start folder' for the File control to point at? Thanks

  • try lowercase media library: /sitecore/media library/Images . also what do you have in logs? Nov 28, 2016 at 8:49

You don't need to set in this way DataSource,

you just need to set DataSource on template field to : media library path (ex: "/sitecore/media library/Images/Social/Connector")

When you will open you will see :

One small issue that I remarked is Search tab is before Browse tab.

    Have you found a solution to the issue of the the search tab being first? Jan 4, 2017 at 1:49

The "DataSource" is only for selection fields (Droplist, treelist and so on) - other field types only support a path, like Sitecore Climber writes.

Further explanations are available in the Data definition cook book (old, but still relevant :)) https://sdn.sitecore.net/upload/sitecore6/datadefinitioncookbook-a4.pdf
