Hi Michael, Could you tell us how many files you have in your directory. Just to give you some idea on performance, I made the following simple test with dir1 containing 1000 files and dir2 containing 10000 files. Then I used the Root TBrowser and the KDE browser dir1: TBrowser=2s KDE=3s dir2: TBrowser=15s KDE=25s The time seems to be proportional to the number of files. Rene Brun "Michael T.
