PgnGlue.bat

Actually you don't need a multiple stars program to merge (append) pgn-files. The following DOS tip will do the trick fast and easy (thanks to Lars Venø Jakobsen). Make a text file with two lines: for %%f IN (*.PGN) DO type %%f>>collect.out ren collect.out collect.pgn and save it as "somename.bat" in the pgn file folder. Be sure your editor doesn't append "txt" to the file name (like "somename.bat.txt"). The extension must be "bat". When you double-click on the icon, all pgn files in the folder will be collected in one file, "collect.out" which is then renamed to pgn. You can even filter the files; if for instance you write (a*.pgn) only files with "a" as first char will be merged. It also works from the command line in DOS, but then you must remember to rename the file. Just replace the double "%%" with a single "%", like in: for %f IN (*.PGN) DO type %f>>collect.out
