If it is an image file, and you want to work with it, try the matlab block processing. By using it, you will load small parts of the file. Your function fun will be applied to each block individually.

 B = blockproc(src_filename,[M N],fun)

In case it is an xml file, try the XML DOM Node mode together with SAX - (Thanks to @Nzbuu for pointing that out), but that seems to be an undocumented functionality.

Also, if it is a textual file of any kind (Unlikely, due to the amount of data), try external tool to split.
