Automatically Rename New Files on Upload with a Sequential Suffix

I have a Document Library with subfolders for storing photos. There will be lots of photos, with more added all the time.

 

I would like to have the photos automatically renamed to "SubFolder_X", where SubFolder is the subfolder in which the file is stored and X is a number that increases sequentially as photos are added (SubFolder_1, SubFolder_2, SubFolder_3, and so on). Simple enough. 

 

But I cannot seem to figure out how to do it.

 

Any ideas?

I think I'll go the route of creating a hidden column that starts at 1 and goes up from there. For now, here is what I did to get the files to rename on upload, to SubFolder_ID:

Split File Path

Expressionsplit(triggerBody()?['{Path}'],'/')

 

Get SubFolder Name

Expressionlast(take(outputs('Split_File_Path'),sub(length(outputs('Split_File_Path')),1)))

 

Send an HTTP request to Sharepoint to get type

Uri: _api/lists/getbytitle('Photos')

 

Send an HTTP request to SharePoint to rename file

URI: _api/lists/GetByTitle('Photos')/Items(@{outputs('Get_file_properties')?['body/ID']})

Headers:

  • Content-type: application/json;odata=verbose
  • IF-MATCH: *
  • X-HTTP-METHOD: PATCH

Body

{'__metadata':
{'type':'@{outputs('Send_an_HTTP_request_to_SharePoint_to_get_type')?['body']?['d']?['ListItemEntityTypeFullName']}'},
'FileLeafRef':'@{outputs('Get_SubFolder_Name')}_@{outputs('Get_file_properties')?['body/ID']}'}

 

NOTE: If you copy+paste what I did, make sure you rename the various Actions as I have done

 

Credit where credit is due: I got the SubFolder stuff from here, and the HTTP stuff from here.

Can you not use the ID of the file? That's already a sequential number that's generated for you. So you would just need to do an update file properties action.

I think that will be my fallback. I have at least a dozen subfolders, and each is going to receive hundreds of photos, so that ID number is going to get long and fast. So I was hoping to start at 1 in each subfolder.

 

I did find this, and it works for renaming files as they are uploaded. I can even include things like who uploaded the file in the name, and the file ID. I set it up to handle the whole library, but still can't sort out how to get the SubFolder name involved. It would be nice if I didn't have to make a flow for each and every subfolder.

Alternatively, if I was going to tackle this and didn't want to use ID, I would store the number in a separate column for easier access. You don't have to show the column in the view of the library.

Make a view in the library that sorts the files highest to lowest based off this new columns.

Do a get files action, targeting that specific view, return 1 item only.

Do a compose action with that number from the column, +1.

In my update file properties action, use this compose action results and put it into the column used for tracking the numbers.

 

I could see a potential where 2 separate flow runs come up with the same number if you have multiple runs going at the same time.
