How can I extract a field value from a folder name?

I have a file that Splunk monitors stored in F:/xxx/2014/file.csv. Is there any way to dynamically take the 2014 folder and assign the 2014 value to a "report_year" field for each event? (Folder may be any year, not just 2014)

Yes, use the rex command with the "source" as the field. Like so:

<base search> | rex field=source "(.*/){2}(?P<year>\d+)/"

This will dinamically look for the second forward slash "/" and then capture all digits in a field labeled year.

Hope this helps
