anixon 0 Posted August 25, 2010 FileGetSize(Test.txt) produces a size of 383 byte which is the value in the files properties however the Size on disc is 4096 bytes so my question is how do I either read or calculate the size on disc for any given file?

Ascend4nt 121 Posted August 25, 2010 Actually most every 'undocumented' API function that I use are documented in some form or another on MSDN. The above function NtQueryInformationFile can be found listed under ZwQueryInformationFile. The difference is 'Nt' is supposed to be called from user mode.
