Loading an entire folder of csvs

Hi. I have a year's worth of data to load from an instrument. There are hundreds of csv files and I'd rather not load them one by one. I have another ipf that does this for a different instrument and altered the code to make it compatible with this other data series.

The csv data looks like:

Device Info
Serial Number 9310-01 93101011006
Record Type Differential
Unit Type Counts
Volume Type m3
Temperature Type ∞C

Minimum Average Maximum Std. Dev. Std. Err.

I believe the loadwave command is at fault, but I am getting an error. I want the files to load starting at line 16 and name the waves as specified. I really only added /L{0,16,0,0} to the loadwave command, but I'm getting an error and it only loads "record" and "location" as individual waves. Any ideas or easier solutions? Thanks

but I am getting an error

Exactly what is the error?

Also, if you posted a couple of sample files, zipped, that will make it possible for someone to investigate.
The error is:
Delimited text load from "20130923_162617 9310-01 93101011006.csv"
Data length: 188, waves: Record_Location
Error loading file - wrong number of waves loaded

I've attached a couple of the files. The files are .csv.
SampleData.zip
Update: I changed the delimiters to ","
Now error reads:
Delimited text load from "20140513_142452 9310-01 93101011006.csv"
LoadWave/B error while parsing T= flag for column 27
Error loading file - wrong number of waves loaded
Think I figured it out. Needed a semicolon at the end of the column info string and needed to remove /R argument from the loadwave. This seems to work now
