Deploying Zdir 4 Private File Sharing System on fnOS
fnOS is a NAS system deeply developed based on the Linux kernel (Debian distribution), supporting installation on mainstream x86 hardware, offering a new choice for domestic NAS systems.

Zdir 4 is a versatile file sharing program with advanced features such as offline downloading, network storage mounting, file preview, and WebDAV, making it particularly suitable for use on NAS devices. This article will guide you through the simple steps to install Zdir 4 on fnOS, creating your personal file sharing system to meet home entertainment collection and file sharing needs.

Setting Up Zdir on fnOS
Open Docker on the fnOS desktop, then select [Local Image >> Add Image >> Add from URL]. Enter the image address: pub.tcp.mk/helloz/zdir, and confirm.

Switch to [Container >> Add Container] and fill in the following information:
- Select Image: Choose the just-pulled
pub.tcp.mk/helloz/zdir - Container Name: zdir, or set your own
- Resource Limits: Memory not less than 512MB, others can be arbitrary
- Check Auto-start on Boot

Next, set the port and storage location:
- The first
6080is your access port, which can be modified - The second
6080is the container port; do not modify this - The first column of the storage location is the Zdir installation path, which you can choose
- The second column of the storage location is the container path:
/opt/zdir/data, which is fixed and cannot be modified

If you want to mount more storage locations, click Add Path and fill in according to the following requirements:
- For the first column path, choose any location you want. The second column container path must start with:
/opt/zdir/data/public/xxx, for example:/opt/zdir/data/public/test - If you want to mount to a private path, the second column container path should be:
/opt/zdir/data/private/xxx, for example:/opt/zdir/data/private/test
Expand the function options and check Run Container with High Privileges. If this is not checked, you will not be able to mount network disks.

Finally, click Create.

Wait about 30 seconds, then access http://IP:6080 to complete the Zdir initialization.

Using Zdir
After setup, open [Zdir Bottom Management Panel - Subscription Management - Use Redemption Code].

Enter any of the following redemption codes to unlock Zdir Pro rights:
fn-TQz40kQeWN4Q2jg3SJLylIF9HBX5J
fn-S0noucWMboXNKAGeHiAwDsdsVYf01
fn-FAZSNEPxiQcvIRKz2hPnHs9wV5FlS
fn-1E0rCKvDBmRqzZHi4dLfAXIA2GekG
fn-ydonZQVNybrffGLKywAAdwFyjnAdM
fn-7LCpJOp3hsQyiJ1sCDBxZTTW1tr65
fn-FN25EAWkD6Jr3CMxFZ0OVaZgfDR4U

fn-sTJwrpV3di5D0S8DitCI3Hg5HzrOo
fn-JeYZcKwarQrTU6ku7nqXhXqgiIE5s
The redemption codes above are valid for three months; repeated use does not extend the validity period. Zdir Pro unlocks advanced features such as offline downloading, mounting third-party network storage, private files, and WebDAV. You can still use basic features for free without unlocking Pro.
Zdir 4 automatically traverses your public and private directories. Files you want to make fully public can be placed in the public directory, while files you do not want to share publicly can be placed in the private directory. You can switch between public and private modes with one click using the button in the top right corner of Zdir, keeping them separate.

Private files can also be shared individually with a password and support setting an expiration time.

You can also create a music folder and place songs in it. Zdir 4 will automatically traverse all songs in the music folder, turning Zdir into an online music player in seconds.

Zdir 4 also includes built-in offline downloading, which requires zero configuration from the user. The offline download feature supports HTTP/HTTPS and magnet links, making downloading easier.

Zdir also supports mounting third-party network storage, having already supported S3/WebDAV/SMB protocols. Through network disk mounting, you can easily integrate files from various locations into Zdir for access and management.

If downloaded tutorial videos cannot be decoded by the browser, you can call the local player for playback.

Through Zdir 4's unique file description feature, you can set a description for each shared file individually, making it easier for visitors to use.

Common text formats support code highlighting and online editing.

If you feel the features are not enough, Zdir 4 also includes a built-in WebDAV server function. You can use any WebDAV-compatible software client to connect to Zdir 4, achieving advanced functions such as music players, video management, and file synchronization, unlocking more possibilities.
Other Notes
Zdir 4 is not only supported on fnOS; you can also install it on any Docker device, including Synology, QNAP, JiKongJian, Ugreen NAS, etc., and even on your VPS or Windows server.
