Get name of doc or pdf in onedrive folder to rename a combined pdf

Posted on by checkspa

I'm a new using PA with Plumsail (thank you to the most patient tech support people, ever) to combine pdfs.

The flow combines 2 pdf files into one but with a static name.

I would like to name that by refering or copying as a string to the file name of a pdf in a completely different folder; this pdf is created and recreated several times during the day.

When I add the step "Create File" after "Merge PDF" in the File Name field I can get the Folder Name but not the File Name of the file it contains.

I want to replace Test02.pdf

You haven't said much about where the file is which you want to use the name from. Is it always the only file in a specific folder? Always the most recently modified file in a specific folder? Is the folder name/path static or dynamic? How would you identify the correct file if you were browsing the folder structure for it? The answer depends on a lot on information you have not provided.

However, once you figure out how to identify the file you can do a List files in folder action then use filter array to filter for the correct file then get its name with first(body('Filter_array'))?['{FilenameWithExtension}'] assuming it's in SharePoint.

In that case, do the List files in a folder action then you can find the newest modified file like this:
1. List files in a folder - pick the folder you want:
2. Add a Compose and enter the expression
sort(outputs('List_files_in_folder')?['body/value'],'LastModified')
3. Now another compose with
last(outputs('Compose'))?['Name']

I create a new file in that folder then run the test:

Thank you but I'm stuck on how to get the output from the 2nd Compose as an input in "Create File" File Name field?
And any suggestions for learning PA? I only started last week out of neccessity but I think this could be really useful

You should see the Compose in the Dynamic content tab of that popup that's on the right of your screen shot.
