How do I get JMP to close pdf files that have been opened to extract information?

[#1]

Since I am new to scripting, I just copied a script from a previous discussion (https://community.jmp.com/t5/Discussions/Batch-processing-files-to-extract-data-into-a-summary-table...) and slimmed it to the stuff I need - only the pdf file names.

Names Default to Here( 1 );
//point to file directory

path = Pick Directory( "Select Directory Containing Data Files" );

//Gets the list of files in the selected file folder
file_list = Files In Directory( path );

// Create beginnings of output data table
dtFinal = New Table( "Final", New Column( "File Name", Character ));

//i=0;open file
nfile_list = N Items( file_list );
For( i = 1, i <= nfile_list, i += 1, 
	//Set Current Directory( dir_DirectoryPath );
	dt = Open( path || file_list[i], );
		// Add information to Final data table
	dtFinal << add rows( 1 );
	dtFinal:File Name[N Rows( dtFinal )] = file_list[i];
);

Unfortunately, I have about 750 pdf files which all open while running the script.

Does anybody know how to automatically close the pdf files?

Thanks a heap for your help

It doesn't look like there's any need to open those pdfs in the first place, since all your script is doing is putting a filename in each row of :File Name.

Names Default to Here( 1 );
//point to file directory

path = Pick Directory( "Select Directory Containing Data Files" );

//Gets the list of files in the selected file folder
file_list = Files In Directory( path );

// Create beginnings of output data table
dtFinal = New Table( "Final", New Column( "File Name", Character ) );

//i=0;open file
nfile_list = N Items( file_list );
For( i = 1, i <= nfile_list, i += 1, 
	//Set Current Directory( dir_DirectoryPath );
	//dt = Open( path || file_list[i], );
		// Add information to Final data table
	dtFinal << add rows( 1 );
	dtFinal:File Name[N Rows( dtFinal )] = file_list[i];
);

But you could do it even quicker and more efficiently.

Names Default To Here( 1 );
path = Pick Directory( "Select Directory Containing Data Files" );
dtFinal = New Table( "Final", New Column( "File Name", Character, Set Values( Files In Directory( path ) ) ) );
