I created a Flow that grabs a folder from a subfolder inside one SharePoint library and moves that folder into another subfolder of the same name to another SharePoint library. It works if I hard-code a part of the URL into the destination URL, but I'm trying to grab part of the URL from the source URL in order to append that to the destination URL so that my Flow knows where to put the specific folder based on its original name.

If I have clients AAA, BBB, CCC, let's say I want to grab folder 67890 from client AAA - testsource/Shared Documents/AAA/12345) - and I want to move that into another library -testDestination/Shared Documents/AAA/67890/Coordinator . So 67890 in testSource will be moved into testDestination's 67890 folder that already exists, and will be renamed "Coordinator".

Also, disregard the 12345 in the images or replace with 67890 as this was the first test folder I moved. That will always change.

What I am ultimately trying to do is grab the AAA/67890 from source URL or Link to Item dynamic content included in the screenshot. Is there a way to use indexof or lastindexof to do that?First part of FlowLast part of FlowtestSource folder (starting point)testDestination (endpoint)Metadata after Flow runs

Yes, that worked @edgonzales and @abm!

I grabbed the Link to item or source URL and named it that.
Took that link and split it - split(outputs('source_URL'),'Documents/')[1]
Grabbing the 'AAA/67890' at the end of the URL
Appended that as Outputs at the end of the Studies/ path like so Studies/Outputs(/AAA/67890/)/Coordinator
This moved the original file to its sister library into the same directory dynamically
Just wanted to post what I did after following edgonzales' instructions in case other users need to see the steps I took. Thanks, Ed!

Hi @angelrodriguez

After the trigger step add a Get File Properties, Select the address and map the id

Link to Item should return the full path of the filename and URL.

From the compose you could use a split statement using / to extract the values you want.

Thanks

Hi there. You may want to check out the Split() function if things are consistent enough. Something like this:

split(outputs('Compose_2'),'Documents/')[1]

Where the stuff in red, you would replace with the dynamic content of your "Source URL". This will split the URL every time it sees "Documents/" and turn that into an array. The [1] indicates you want the second part of the array (everything after the delimiter). Here's a cool video on the function.

Keep us posted.
