|  Can't delete Thumbnail Cache under Windows 7 under Vista, i used to delete my Thumbnail Cache files : Quote:
Code: if ( !DeleteFile( filesC.Item( i ) ) )
{
DWORD dwAttC = GetFileAttributes( filesC.Item( i ) );
dwAttC &= ~( FILE_ATTRIBUTE_READONLY );
SetFileAttributes( filesC.Item( i ), dwAttC );
DeleteFile( filesC.Item( i ) );
}
Under Windows 7 this is not the case, those files are not deleted or regenerated even after restarting the system. Am i missing something, or there is some way to notify explorer.exe to delete those files? Thanks in advance. | |

| I'm guessing you need to look at the return result of DeleteFile() and generate some kind of meaningful error message.

| Under Vista: -The first call to DeleteFile returns 0, and GetLastError returns ERROR_ACCESS_DENIED. -After changing the file attribute, DeleteFile returns non-zero value(success). -Thumbnails are regenerated automatically after restarting explorer.exe. Under Windows 7: -The first call to DeleteFile returns 0, and GetLastError returns ERROR_ACCESS_DENIED. -After changing the file attribute, DeleteFile returns 0, and GetLastError returns again ERROR_ACCESS_DENIED. -Thumbnails are not deleted or regenerated even after restarting the System. |

As for deleting them, try blanking out the file's security descriptor before deleting and see if it works.
