How to get the file size given a path?

Question

I have a path to file contained in an NSString. Is there a method to get its file size?

Answer 1

This one liner can help people:

unsigned long long fileSize = [[[NSFileManager defaultManager] attributesOfItemAtPath:someFilePath error:nil] fileSize];

This returns the file size in Bytes.

Answer 2

In Swift 3.x and above you can use:

do {
    //return [FileAttributeKey : Any]
    let attr = try FileManager.default.attributesOfItem(atPath: filePath)
    fileSize = attr[FileAttributeKey.size] as! UInt64

    //or you can convert to NSDictionary, then get file size old way as well.
    let attrDict: NSDictionary = try FileManager.default.attributesOfItem(atPath: filePath) as NSDictionary
    fileSize = dict.fileSize()
} catch {
    print("Error: \(error)")
}

Answer 3

Swift4:

        let attributes = try! FileManager.default.attributesOfItem(atPath: path)
        let fileSize = attributes[.size] as! NSNumber

Answer 4

Swift 2.2:

do {
    let attr: NSDictionary = try NSFileManager.defaultManager().attributesOfItemAtPath(path)
    print(attr.fileSize())
} catch {
        print(error)
}
