Hi all, I created a map file like this : HANDLE hMap=CreateFileMapping(hFile, NULL, _dwProtect, 0, _dwSize, _strMapName); but now I need to increase its size and create a new view on it!! does someone know how to to that the right way?? Thank you so much :)

To start over, can't you just call
UnmapViewOfFile()followed byCloseHandle()?

Your sentence is incomplete. What happens when you call
MapViewOfFile()the second time?

for example when I resize the file from 4KB to 8KB, I expect that MapViewOfFile() return a buffer size of 8KB but I get only 4KB !!!

This is to be expected - that is how file-mapping objects work. You should use the ZwResizeSection native-API if you want to resize the file-mapping object. Lots of info on google about this. James
