How to only read the first 100 bytes and the last 100 bytes from a Binary file?
Hi,

Is it possible to read a file only to get the first 100 bytes from the begining and the last 100 bytes at the end? I have to get info from files that are in the first 100 bytes and in the last 100 bytes of the file and some of these files are 600Mb -1 GB in size. I am getting "outofMemory.." exceptions on the largest files and the other files take "forever" to get the first and last 100 bytes. Thank you!

Look up the fseek() and ftell() functions. Use them in combination to achieve what you want.

fseek() and ftell() do it well. Thank you for your tip!
