I have a binary file with some rubbish at the start of it. I'm using MATLAB to find the start of the good stuff and want to copy the rest of the file from for example position 1388 to the end into a new file. I know I can easily read the file hexadecimal by hexadecimal into a new file, but I'm looping through a lot of big files and I'm gonna be doing this often, so I was hoping someone knows some way of dumping parts of files into new files?
