I use the following methods to get the visibility of files in the file system, but still some file some up in my list that do not show up in the Finder. Any suggestions to get results more like the Finder gives?

...
NSMutableArray *pathCont = [NSMutableArray arrayWithArray:[fileMan contentsOfDirectoryAtPath:path error:&fmErr]];
if ([pathCont containsObject:@".hidden"]) {
NSArray *hiddenList = [[NSString stringWithContentsOfFile: [path
stringByAppendingPathComponent:@".hidden"]]
componentsSeparatedByString: @"\n"];
[pathCont removeObjectsInArray: hiddenList];
}
int i;
for (i = 0; i < [pathCont count]; i++) {
NSString *aFile = [pathCont objectAtIndex:i];
if ([self isVisible:aFile])
// code
}
...


- (BOOL)isVisible:(NSString *)path
{
if (([path hasPrefix:@"."]) || ([path characterAtIndex:([path length] - 1)] == 13)) return FALSE;

OSStatus err;
FSRef fileRef;
Boolean isDirectory;
err = FSPathMakeRef((UInt8 *)[path cStringUsingEncoding:NSASCIIStringEncoding], &fileRef, &isDirectory); // ? noErr : fnfErr;
CFBooleanRef isInvisible;
BOOL isVisible = YES;

if (noErr == err)
err = LSCopyItemAttribute(&fileRef, kLSRolesAll, kLSItemIsInvisible, (CFTypeRef *)&isInvisible);

    if (noErr == err) {
        isVisible = (CFBooleanGetValue(isInvisible) == FALSE);
        CFRelease(isInvisible);
    }
    return isVisible;
}
