hadd, small target

Hello

I use hadd to add hsitograms from 2 files to a target file, but somehow the resulting target is smaller than the largest source file. Is this normal ?

Here is what I do (the target file does not exist before invoking hadd):

hadd Profile90ComponentsMC.root Profile90ComponentsMC.root.back Profile90ComponentsMC.lapp.root

ls -l Profile90ComponentsMC.*
-rw-r--r-- 1 margar margar 45665 2008-05-13 14:36
Profile90ComponentsMC.lapp.root
-rw-r--r-- 1 margar margar 2657679 2008-05-13 14:48 Profile90ComponentsMC.root
-rw-r--r-- 1 margar margar 2707599 2008-05-13 14:37
Profile90ComponentsMC.root.back

There are large number of histograms within these files and it is somewhat difficult to check whether I had lost some histograms or not.

Thanks,

               Margar
