Does anyone know what this file is for ?

FYI, the /proc file system really isn't a file or directory on your hard drive. It
is merely a representation of kernel variables, stats, and other CPU/RAM
oriented information.

It is similar to /dev . The files there aren't really files. They're just file
handles that are used to access hardware devices through the kernel drivers.

/proc/kcore is a map of all the physical RAM in your system, hence 128MB
and 256MB "file" sizes. It takes no space at all in your normal file system.
