If you have the memory, you might want to read the whole file into memory, manipulate it there and then dump the results back to disk.

That could be faster depending on a number of factors e.g number of search operations, insert/delete operations, disk performance or size of file.
But this method of loading all the data and dumping the useful data back to the file works like putting the data to a newly created file. My question is whether there exist a more efficient library for me to insert/delete characters in any position of a file. Anyway, thanks for your response.

       partition for this livecd image, all the operations are interactive and have warnings f they will damage your old data on your USB disk.

       mic-image-manager has a GUI tool for it.
