File Keyword/Extension :
-Any File Extension in '*.*' format. If no file extension input is provided, output will be all files within specified directory.
-Keywords can also be provided to narrow search where asterisk (*) is a wildcard(example:
'*sample*.csv' will output all files ending in sample___.csv such as fastsample1.csv or sample0132.csv).
-Multiple filenames can be provided, separated by spaces (in the form '*.ext1 *.ext2' where all of the files of all of the extensions listed will be output.
-Any of the above can be combined to create large keyword/extension combinations.

Directory : Location of folder to search within. If no directory is provided, the current working directory will be used. NOTE: Supplying a directory will add that directory to the current working directory. To return to old directory,use CD.

Specific Files: Matrix used to select specific files from output list. If no matrix is provided entire list will be output.
