Hi Andrew, I decided not to let the fact that I have never written any FS code stand in the way of making suggestions :-) :-) Do you think it would be better to make the defragmentation part of the normal operation of the FS rather than a seperate application. For example, if you did a fragmentation check/fix on the last close of a file you would know that coherency issues were not going to be important. It might also give you some way to determine which files were important to keep close together.
