An installer may be on the way. For now, follow the steps below.

EncFS can be compiled and used on Cygwin.

Here are the required steps.

1. Install Cygwin (64 bits version preferred because of this) with the following packages :

• cmake
• make
• gcc-g++
• gettext-devel
• openssl-devel
• procps-ng
• perl-test-harness

2. Install WinFsp, latest stable is preferred.

3. Using Cygwin terminal, install WinFsp FUSE into Cygwin :

cd /cygdrive/c/Program*/WinFsp/opt/cygfuse

sh install.sh

4. In /usr/include/fuse/winfsp_fuse.h :

If needed, modify : return cygwin_create_path(

To : return (char *)cygwin_create_path(

(see https://github.com/billziss-gh/winfsp/pull/154)

5. Get last EncFS version (at least 1.9.5).

6. Using Cygwin terminal, build and install as usual.

Use as usual, from a Cygwin or Windows terminal.

You may also consider SiriKali GUI (GitHub).

Integration tests regarding symlinks may fail, and their behavior depends on some options.
If you care about symlinks, you may consider :

• value of winsymlinks in CYGWIN environment variable ;
• usage (or not) of the limited -o rellinks option (see more in billziss-gh/winfsp#153).

For performance matters, you may consider :

• the exec / notexec Cygwin mount option.

For performance and ACLs matters, you may also consider :

• the noacl Cygwin mount option.

Regarding IVs, which are based on inode numbers : depending on configuration, they may lead to some problems, as file IDs (used by Cygwin to compute inode numbers) may not be consistent on Windows (see 1 and 2). If not sure, they can be disabled during EncFS configuration.
