Help needed for a batch file to extract data from text files

[wharfbanger]

Hi,

I have over 1000 text files.  The files are located in about 40 subdirectories, all within a single parent directory.  All files are in the same format (example file below).  I would like to be able to extract data to a single output txt file as follows:

2014-02-26 21.51.53.000.tif, -38.72672, 176.05866, 1413.2

Note the first output field is the input filename, but with the suffix changed to .tif. 

I am hoping someone can help me write a batch file that would do this.  I have no experience writing batch files.

Regards,
Mark
