FTP Server Solid Explorer: Setup Guide

Yes, Solid Explorer can connect to an FTP server directly. You add the server in its built-in connection manager, then browse and transfer files over FTP, SFTP, and WebDAV. This guide covers the exact steps, common connection problems, and how to pick the right protocol for your needs.

What Solid Explorer Is

Solid Explorer is a file manager for Android with a dual-pane interface, cloud storage support, and a built-in FTP client. It is not a server itself, but it can act as a client to connect to remote FTP servers. The app has been around for years and is known for its clean Material Design and lack of ads in the paid version. Many users choose it because it handles both local files and remote connections in one place, so you do not need a separate FTP app.

How to Add an FTP Server

Adding a server takes about a minute. Open the app and follow these steps:

1. Tap the hamburger menu (three lines) in the top-left corner.
2. Select New connection (or the plus icon).
3. Choose FTP from the list of protocols.
4. Enter the server address (e.g., ftp.example.com) and port (default is 21 for FTP, 22 for SFTP).
5. Enter your username and password. Leave password blank if the server allows anonymous access.
6. Tap Connect and wait for the file list to load.

Once connected, the server appears under Connections in the navigation drawer. You can bookmark folders for quick access later.

FTP vs SFTP vs WebDAV

Solid Explorer supports several protocols, and the one you choose matters for security and compatibility.

• FTP – Plain text, no encryption. Fine for a home network or a test server, but avoid it on public Wi-Fi because your password travels in clear text.
• SFTP – Runs over SSH, fully encrypted. Use this whenever possible, especially for internet connections. Port 22 is standard.
• WebDAV – HTTP-based, often used with Nextcloud or ownCloud. Can be encrypted with HTTPS.

If your server admin gives you a choice, pick SFTP. It is the same effort to set up in Solid Explorer but much safer.

Common Connection Problems

Even with the correct credentials, connections can fail. Here are the most frequent issues and their fixes:

• Timeout or “Cannot connect” – Check that the server is reachable from your phone. Try a different network (e.g., mobile data) to rule out Wi-Fi firewall blocks. Also verify the port number – many home routers use non-standard ports.
• Authentication failed – Double-check the username and password, especially case sensitivity. Some servers require the username in the format user@domain.com for virtual hosts.
• Passive mode errors – Solid Explorer uses passive FTP by default. If the server is behind a strict firewall, the admin may need to open a range of data ports. You cannot change this from the client side.
• Certificate warnings (SFTP) – When you connect the first time, the app asks you to verify the server’s host key. If it changes later, that is a red flag – do not accept unless you know why.

If none of these help, try connecting with a desktop FTP client (like FileZilla) to isolate whether the problem is the server or the app.

Transferring Files and Managing Remote Content

Once connected, you can copy, move, rename, delete, and stream files just like local ones. To upload a file, long-press it in the local pane and select Copy, then navigate to the remote folder and tap Paste. Downloads work the same way in reverse.

You can also edit text files directly if you have a text editor installed, and play media files from the server without downloading them first, as long as the connection is fast enough. For large transfers, Solid Explorer shows a progress notification and lets you queue multiple files.

Security Considerations

Using FTP over the internet without encryption exposes your credentials to anyone on the network. Always prefer SFTP or FTPS (FTP over SSL) if the server supports it. Solid Explorer supports FTPS as well, though the option is labeled “FTP” with a security setting. When you create a new FTP connection, look for a Security dropdown – choose Explicit FTPS or Implicit FTPS if available.

Also, avoid storing passwords for public servers. Solid Explorer offers a lock option (PIN or fingerprint) to protect your connections. Enable it in Settings > Security if you have sensitive data.

Alternatives to Solid Explorer

If Solid Explorer does not meet your needs, other Android file managers with FTP support include:

• CX File Explorer – Free, supports FTP/SFTP/WebDAV, includes a server mode.
• Material Files – Open-source, lightweight, but FTP support is limited (no SFTP).
• ES File Explorer – Was popular but now contains ads and bloatware; not recommended.
• Total Commander – Classic dual-pane manager with FTP plugins.

For a dedicated FTP client, AndFTP and Turbo FTP are options, but they lack the local file management features of Solid Explorer.

Frequently Asked Questions

Does Solid Explorer work with FTPS?
Yes. When adding a new FTP connection, tap the security dropdown and select “Explicit FTPS” or “Implicit FTPS”. Most servers use explicit FTPS on port 21.

Can I use Solid Explorer to host an FTP server?
No, the app is only a client. To share files from your phone, use an app like Solid Explorer’s own “FTP Server” feature? Actually, that is not included. You would need a separate app like FTP Server or Primitive FTPd.

Why does my FTP connection work on Wi-Fi but not on mobile data?
Many mobile carriers block incoming connections on non-standard ports. Also, your phone’s firewall or the server’s IP allowlist may only permit certain networks. Try connecting to the server’s public IP instead of a local one.

Is Solid Explorer free?
The app has a free trial for 14 days, after which you need to purchase a license. The paid version removes ads and adds features like cloud storage and root explorer.

Can I edit files directly on the FTP server?
Yes, if the file type is associated with an editor on your device. Tap and hold the file, select Open with, and choose your editor. Changes are saved back to the server when you save the file.
