iOS - Get sum of filesize in directory

You can get the size of a file like so

NSError *attributesError = nil;

    NSDictionary *fileAttributes = [[NSFileManager defaultManager] attributesOfItemAtPath:URL error:&attributesError];

    int fileSize = [fileAttributes fileSize];

So you can maybe iterate through all the files in the folder and add up the file sizes...not sure if theres a direct way to get the directory size, also theres this SO post talking about this aswell, you can find a solution here

To find the creation date of the file you can do

NSString *path = @"";
    NSDictionary* fileAttribs = [[NSFileManager defaultManager] attributesOfItemAtPath:path error:nil];
    NSDate *result = [fileAttribs valueForKey:NSFileCreationDate]; //or NSFileModificationDate

Hope it helps
