getCompressedSize

get the on disk size of an NTFS compressed file. if the file is not compressed, these functions will return the same value as the file's real size. if the file does not exist or is inaccessible, the return value will be null.

usage

callback:

fswin.ntfs.getCompressedSize(file, callback);

async:

var result = await fswin.ntfs.getCompressedSizeAsync(file);

sync:

var result = fswin.ntfs.getCompressedSizeSync(file);

• file is a string that specifies the path to a file
• callback is a function that takes only one argument result
• result is a number to indicate the commpressed size of the file or null when failed.

example

var fswin = require('fswin');
var file = 'd:\\testfile.txt';

//sync
console.log('the compressed file size is: ' + fswin.ntfs.getCompressedSizeSync(file) + ' Bytes');

//async
console.log(fswin.ntfs.getCompressedSize(file, function (result) {
	console.log('the compressed file size is: ' + result + ' Bytes');
}) ? 'job queued' : 'failed to queue job');
