Hello again, Thanks for the quick answer Rene. I can understand some of the reasons for this feature, however, I'm suprised that some kind of cleanup mechanism that reclaims unused disk space doesn't exist in ROOT. I'm thinking of one of these maintenance programs that only get's used every-so-often. I think it would be quite useful esp. since every so often a mistake such as writing much larger trees than expected will irreversibly increase file size and force me to recopy what I need into a new ROOT file before deleting the old. More comments anyone ?
