Scanning directories for file type

I am working on a little app for my Mac that will scan directories for a file type like, "mov" files. I have NSOpenPanel pop up and then I select the directory and when I hit OK It saves the directory to an NSMutableArray. I then sort through the Array to see if the file is of .mov type or another directory. If it is a mov I save it to a new array or if it finds a directory it saves it to a different array. It works fine except it is adding anything with .app extension to the directory array. here is a list of the results and code. At the bottom you can see the XP.....app

After the OK button is pressed on the NSOpenPanel window

Code:

if (result == NSOKButton){
        BOOL dirPathVerify = NO;
        dirPath = [[NSString alloc]initWithFormat:[getFile filename]];
        NSArray *dirContents = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:dirPath error:nil];
        
        for (int i = 0; i < dirContents.count; i++) { 
           NSString *aPath = [dirContents objectAtIndex:i];
           NSString *fullPath = [dirPath stringByAppendingPathComponent:aPath];
            
            if ([filemgr fileExistsAtPath:fullPath isDirectory: &dirPathVerify] &&dirPathVerify ) {
                [dirArray addObject:aPath];
            }
            else if ([[aPath pathExtension] isEqualToString:@"mov"]) {
                [movArray addObject:aPath];
            }
        }        
        NSLog(@"Mov Array has %@", movArray);
        NSLog(@"dir Array had %@", dirArray);

    }
    [movArray release];
    [dirArray release];

}

 

I am not sure? This is some new territory for me. I thought it would be fun to expand my coding a bit this weekend. I wanted to generate a list with the .mov files on my external hard drive to better help me find clips for the videos I work on. As I scan a folder(directory) it finds mov files and other directories that I want to scan through. So in 1 Array I gather the mov information and in the second Array I gather the other directories paths to scan later.

I found this line of code on line but I don't get all of it?

Code:

if ([filemgr fileExistsAtPath:fullPath isDirectory: &dirPathVerify] &&dirPathVerify )

I understand the first part and it checks to see if the file exists at that path. The next part isDirectory I think is self explanatory if it is a file or directory. But the next 2 with the & and the double &&? From reading C I know the & refers to the address of the variables location but the double && I have no clue?

 

Hi Jim,

YES

I found myself searching for for video clips I shot half a year ago on my drive. I thought I would build a data base which could present thumbnails and meta data of all the clips on my drive with an extension of , mov. This sounded like a great opportunity to learn something new.

From your code it looks like I started off using wrong code, went with what I knew so far. I got it working but was struggling with what you mentioned of going into sub-directories and then their sub-directories to locate these files and so on.

I have never worked with NSFileManager's enumeratorAtURL so this sounds like a fun challenge for Saturday. I will read up on and it and thanks for pointing me in the right direction!!!
