it’s like hard link on unix

when user see c:\temp\protected. it’s really folder located in d:\relocated.
protected folder on c:\temp\ is just alias or link.
for this, i tried reparse function. but i could not success, yet.

if i click protected folder, 'file or directory is moved… ’ message
displayed
on hookdone function
…
if (_strnicmp(fullPathName, SECUREFOLDER, strlen(SECUREFOLDER)) == 0)
{
//UNICODE_STRING fullUniName;
ANSI_STRING bar;
char sbuff[512];
char spath[512];
int spathlen;
RtlZeroMemory(sbuff, 512);
RtlZeroMemory(spath, 512);
strcpy(spath, REDIRECTFOLDER); //µð·ºÅ丮¸¦ redirect , by kish 2005.4.8
// RtlStringCbCopyA(spath, 512, REDIRECTFOLDER);
spathlen = strlen(spath);

spathlen, LEN_OF_FOLDER));
