What would be an efficient way to extract only all of the *.csv files (not other files inside) from inside a hundred zip files in a single directory? Then I need to make one large file with each CVS file appended together although stripping off header line 1 from files 2,...,n.
If it works well I would like to use 7-Zip's 7za.exe the command line version or other solutions that are self contained and don't require installation on a WinXP platform. The zips contain other data I don't need.
Simple appending is easy with file1+file2+..., but how about dropping the header?
