Not able to close table in a for loop

[#1]

Hi,

I want to use a for loop to keep import multiple files and close it after concatenate. the import multiple and concatenate is working but not the close(). I tried wait(), still not working. Not sure what I did wrong. 

dt1 = New table();
dir = {"dir1","dir2","dir3"}; //can have many dirs
for(i=1, i<= N Items(dir), i++,
	dt[i] = Multiple File Import(
	<<Set Folder( path1||"\" || dir[i] ),
	<<Set Show Hidden( 0 ),
	<<Set Subfolders( 0 ),
	<<Set Name Filter( "*.csv*;" ),
	<<Set Name Enable( 1 ),
	<<Set Add File Name Column( 1 ),
	<<Set Add File Size Column( 0 ),
	<<Set Add File Date Column( 0 ),
	<<Set Import Mode( "CSVData" ),
	<<Set Charset( "Best Guess" ),
	<<Set Stack Mode( "Stack Similar" ),
	<<Set CSV Has Headers( 0 ),

	) << Import Data,


dt1 << Concatenate(dt[i],Append to first table( 1 ));

close (dt[i],nosave); //this is the step dont seems taken effect. table not close
);

If I remember correctly Multiple File Import returns a list and if that is the case you will have to loop over that list while closing the data tables.
