Win32 way to determine if a file is not accessible/private - gretty - Oct 16, 2011
Hello
In win32 c++; is there a way to determine if a folder/file is accessible? You know how if you try to access a certain folder in the C:/Windows directory & you will get a popup saying "This folder is not accessible".
Maybe there is a file attribute constant that signifies that the file is private? Maybe something like FILE_ATTRIBUTE_PRIVATE?
Code
WIN32_FIND_DATA dirData;
while (FindNextFile( dir, &dirData ) != 0 )
{
// I made the following constant up
if ( fileData.dwFileAttributes & FILE_ATTRIBUTE_PRIVATE )
{
// file is inaccessible
}
}Or is the only way to know by going:
Code
dir = FindFirstFileEx( (LPCTSTR)directory.c_str(), FindExInfoStandard, &dirData, FindExSearchNameMatch, NULL, 0 );
if ( dir == ??? ) { the file is inaccessible }* - -Felix- - Oct 16, 2011
Well, im not sure what you mean with private. But you are actually giving FindNextFile() a WIN32_FIND_DATA structure as output parameter. And as you can see here : http://msdn.microsoft.com/en-us/library/windows/desktop/aa365740(v=vs.85).aspx
There are some things that you can find out about the file by checking it after calling FindNextFile().
I don't think that there actually noticeable more to find out about a file, because even this function http://msdn.microsoft.com/en-us/library/aa363788(v=VS.85).aspx would not tell you more than the WIN32_FIND_DATA-struct.
