Â Maybe you read a lot about fragmentation of files.
If you are an longtime Mac-User, in the past at OS 7-9 days, with old and slow harddiscs, fragmentation was an awful thing.
Since HFS+ and Mac OS X Panther, the file fragmentation isnÂ´t the big problem anymore - if you have much freespace (>= 20 % free).
OS X 10.3+ try to avoid fragment an file at creation time and also tries to defrag files below 20 MB size.
So far , so good.
My GUI-Tool ShowVolumeFragmentation, which uses the hfsdebug commandline tool from Mr. Amit Singh, shows/prints out your file and freespace fragmentation state of any volume.
