float freeSpace = 0.0f;  
NSError *error = nil;  
NSDictionary *dictionary = [[NSFileManager defaultManager] attributesOfFileSystemForPath:kSongsFolder error: &error];  

if (dictionary) {  
    NSNumber *fileSystemFreeSizeInBytes = [dictionary objectForKey: NSFileSystemFreeSize];  
    NSLog(@"%d",fileSystemFreeSizeInBytes);
    freeSpace = [fileSystemFreeSizeInBytes floatValue];  
} else { 
    //Handle error
