windows-fs

🌀 Windows utilities when working with the file system. Intended for use with electron or nodejs.

Installation

npm install windows-fs

Example

import { mount, statByDriveLetter } from 'windows-fs'

mount('server', 'share')
  .then(letter => statByDriveLetter(letter))
  .then(log)
// -> { freeSpace: 10700152832, size: 53579083776 }

Note that all paths are written in unix style format to ease the developer pain from double escaping the backslash in windows. All other path characteristics stay the same (a:/, //server).

API

isMounted

Checks if a given unc path is already mounted. If it's mounted returns the drive letter otherwise returns undefined.

Parameters

• unc String Unc like path server/share$

Examples

isMounted('server/share$')
  .then((letter) => {
    // mounted network drive hasn't been found
    if (!letter) return
    // found
  })

Returns (String|undefined) The drive letter or if not found undefined

mount

Mounts a network drive to the next available drive letter and returns a the drive letter which it was mounted on.

Parameters

• unc String A UNC path like //server
• path String A path like some/path/to/folder
• credentials Object= user and password to log into a network

Examples

// (given letter Y: is free)
mount('server', 'c$')
  .then(log)
  .catch((err) => console.error('failed to mount', err))
// -> Y:

Returns Promise Resolves to the drive letter which the path was mounted on, rejects when the command fails

mountedDrives

Gets a list of mounted drive letters and their respective unc paths.

Returns Array Array of { unc, letter } tuples

statByDriveLetter

Gets stats by a given drive letter like the current size of the hdd etc. This also works for drives in a network. Use statDrives() when their are no login credentials, otherwise use this function to avoid firewall settings.

Parameters

• letter String The drive letter which the hdd was mounted on

Examples

statByDriveLetter('Z:')
// -> { freeSpace: 10700152832, size: 53579083776 }

Returns Promise A promise which resolves to { freeSpace, size }

statDirectory

Gets various metadata about the directory and the files in it using a recursive walk.

Parameters

• path String Absolute path

Examples

statDirectory('c:/temp/log')
// -> { count: 4, size: 32636 }

Returns Object Object with size (directory size in bytes), count (file count) and files (list of files in the directory and their respective metadata)

statDrives

Gets various information about all the drives mounted on a given computer

Parameters

• computer String Computer name

Examples

statDrives('computer-name').then(log)
// -> [{ deviceID: 'C:', freeSpace: 4324564, ...}, ...]

Returns Promise Resolves to { json, stdout, stderr }

toUncPath

Creates a windows path given a server name and a unix path.

Parameters

• server String Server name
• share String Path

Examples

toUncPath('server', 'some/path/to/a/log')
// -> `\\server\some\path\to\a\log`

toWindowsPath

Replaces / with \ so we can use an unix path and convert it to a windows path.

Parameters

• path String Unix style path

Examples

toWindowsPath('some/random/folder')
// -> some\random\folder

Returns String Windows style path

unmount

Unmounts a network drive given a letter and returns the letter.

Parameters

• letter String Network drive letter

Examples

// (given letter Z: is mounted)
unmount('Z:')
  .then(log)
  .catch((err) => console.error('failed to unmount', err))
// -> Z:

Returns Promise Resolves to the drive letter when successful, rejects when the command fails

Tests

There is an extensive test suite which is not generalized for public tests because its not independent of the system it's running on. We haven't found a way to get around that for windows-like utilities.
