I'm looking for a program that can mount SFTP folders on Windows, that:

  • Is gratis and open-source
  • Runs natively on Windows (10)
  • Mounts to a drive, not to a folder
  • Supports password-encrypted SSH2 (RSA) keys
  • If open-source is not a hard requirement, you might take a look at ExpanDrive. Works quite reliable, I've used it at a customer's site some years ago (pre Win-10 times). Avaliable on Windows and MacOS. – Izzy Dec 30 '16 at 10:16
  • @Izzy: But ExpanDrive isn't gratis, is it? – wb9688 Dec 30 '16 at 10:40
  • To be honest, I don't remember these details. It was years ago, and for a company. AFAIR there was at least a free trial, maybe even free for personal use. Should be listed on their site. – Izzy Dec 30 '16 at 10:57


Haven't used windows in 16 years but I recall that Explorer (file manager) could handle protocols it knows about like FTP. if that is still the case, WinSCP will integrate with it/register as a protocol handler.



There is also sshfs, and a version for Windows is available. This will (according to docs) use a drive letter.

    I didn't ask for Explorer integration, I asked for mounting, so WinSCP isn't an option, btw win-sshfs hasn't been maintained for 4 years, but it brought me to a fork of it called "WinSshFS Foreveryone"… – wb9688 Dec 31 '16 at 6:50

    WinSCP does not answer the question – endolith May 17 '19 at 1:21

Winfsp http://www.secfs.net/winfsp/download/ and its associated sshfs driver is free and opensource.

One advantage was being able to saturate a 1 gigabit link at 80 megabytes per second.

It doesn't seem to support key based logins yet, but password based logins work perfectly.

  • I was unable to use memfs. Cmd line instructions looks outdated. But sshfs works as advertized – lowtech Oct 16 '18 at 15:37

https://github.com/Foreveryone-cz/win-sshfs Open Source

Main features:

Windows 10 Support
Puttyant (Pageant) support
Support for Android hosts (tested with CyanogenMod 11 [Android 4.4], requires busybox to be installed)
Spooldrive - remote hosts can by mounted as directories on same virtual drive
archive flag of file in windows represents and controls permission for group:
    ON => group have same rights as owner
    OFF => same rights as others)
Ability to use Proxy for connections
Send Keepalive packets. (Not configurable, each 60sec hardcoded)
  • Looks like sftpnetdrive only allows 1 connection at a time, which may be a bit limiting for some. – Artem Russakovskii Mar 11 '19 at 19:06

    Sonamor: The question specifically requires "Is gratis and open-source", so better remove the first item and look up the 3rd item. Thanks! – Nicolas Raoul May 20 '19 at 7:44
