File Search and process

I would like to satisfy the following requirements in KNIME 2.7.4+.


a. Search for a file[s] in a given drive or directory.

b. Enumerate the matches and report the no of files found.

c. For each match, process the file and collect the records from the file.

I know we can code step 3 using 'Table row to Variable loop'. Can you help with steps 1 and 2. If I need to install any extensions, please let me know the update path.


Hi Srao,


you need the List Files node. Afterwards the enumeration maybe with the counter node.  To get the number of found files, this would be the numer of rows, you can use the Statistics Node (or the Group By or Extract Table Dimension)
