Copy the file, skipping the part you want to delete.

Or if you are going to delete a lot of stuff, keep track of all the
deletions in a sorted list and do them in a single copying operation.
 
thanx

i thaought about doing that, just reading the entire file to a string,
removing the block i dont need and then writing that block to a new file
(with the same name) and deleting the other file...but that seems to more
resources then needed..and im running this app on a Pocket PC, so my
resources are liminted as is.

Of course, you do not have to read the whole file into a string before
outputting any of it. That would require a lot of memory. Read individual
characters or small blocks of characters and write them out.
