Good morning,

I have about 400 shapefiles, each containing one polygon, that I would like to combine into one master.  I need to remove numerous fields since each GPS unit used to collect the data has different default fields/properties.  Additionally, I need to add several fields for queries which are not defaults for any GPS units (i.e. Permit #, Date, Mineral, Status, etc). So, how to proceed?  I am new to ArcInfo, and there is currently no geodatabase structure in place.   Thank you very much!
