WinFSP: How to use it

Hey Community,

if you are on Windows and experience trouble with Dokany or WebDAV, since Cryptomator 1.5.9 you can try a new virtual volume provider: WinFSP.
We implemented support for it because it might lead to less code maintenance in the long term and it showed promising stability and performance in test runs.


While the above sounds cool, please bear in mind that WinFSP is still not 100% integrated into the app.
There are two main issues:

  1. Directories cannot be used as mount targets.
  2. Custom mount options differ and hence they must be reset. The older options will be lost afterwards.

How to use

Just follow these steps:

  1. Download and execute installer from the WinFSP homepage: Download · WinFsp

  2. Start Cryptomator (or restart it, if already running), open general preferences, go to the virtual volume tab and select the FUSE in the dropdown menu.

  3. For vaults with custom mount options enabled, untick the regarding checkbox.

That’s it, you are ready to go.

We welcome feedback about stability, performance and solved issues!
