URI explanation

Hi,

Not sure about a concept in Knime named URI. I need to move some files around to support a workflow. Using the list files nodes and then copy/move file nodes I get an error. The dialog cannot be opened for the following reason: No column in spec compatible to ‘URIDataValue’. Not sure what URI is? Looking at community it mentions going to documentation but that talks about URL formats. Can someone guide me?

Thanks,
Jeff

Hi @Jeff,
URI is a “Uniform Resource Identifier” and points to a resource, e.g. a file or a website. The List Files node outputs an URL, which is a “Uniform Resource Locator”, which is a special type of URI. This URL is stored in a string column, so you will need to convert that to an URI first using a String to URI node. After that, the Copy/Move Files node should allow you to open the dialog just fine.
Kind regards
Alexander

Hi @Jeff

I built a workflow that demonstrates the use of URI and URL and the like

Then there are examples how to copy (or move) files using URI
