# Slow file dialog in Netbeans (and other Java apps) ...and the amazing solution

The opening of the file dialogs of most of my Java apps (excluded JEdit, Eclipse) became really slow (10 seconds). I supposed the network-drives, virus-scanners etc. to cause the problem. It turned out, that Jars/Zips at the desktop (on windows...), cause the slow-down. After cleaning my desktop, netbeans 5.5/6 and other Java apps became fast again.Like in real life, mess on a desktop slows down the performance... [Thanks michael bien for the solution, I asked many people at workshops, projects, conferences, but my young brother knew the solution :-)]
