FileSystem^? DataSource^?

For example, you can choose a specific directory and (optionally) recurse through all subdirectories to sort and extract the ten biggest files, the ten oldest files etc.

You could tie this in with a Text DataSource^? that reads an access log to plot the file size versus the number of times accessed, or the files that contributed the most to bandwidth etc.

You could use it to filter a log to only retain certain files of interest (by joining with filtered or extracted filesystem records)

You could even use the FileSystem^? datasource to detect the name of the most recently updated log file and pass it as a parameter to a TextDataSource^? to load that specific one (idea related to Mantis 407).
