Directadmin provides an easy-to-use web interface to manage your website files, allowing for uploading, downloading, editing, and deleting files. Here’s how you can manage website files using Directadmin web control panel:
Access Directadmin Control Panel: First, log in to Directadmin Control Panel using your credentials.
Go to File Manager: Navigate to "File Manager" via Directadmin control panel under the "File Management" tab. You'll also need to select the domain name associated with the website whose files you want to manage.
Upload Files: The File Manager will open, and then you can upload files to your website by selecting the "Upload" option at the top, and then either drag-and-drop the files or click to browse on your local machine.
Download Files: To download files, select the file(s) you want to retrieve from the remote server and click the "Download" button to save it to local storage on your computer.
Edit Files: To edit a file, select it in the file manager, then press "Edit." From here, you can use the built-in text editor to modify your file content and then save the changes. If you prefer an alternative editor and have access to SSH, you can also use a command-line editor like vi or nano to edit files.
Delete Files: To remove any files, select them in the file manager and click the "Delete" button at the top of the screen. A warning message will appear, so confirm the deletion by clicking "OK."
Copy/Move Files: In the File Manager, select the files you want to copy/move and click either "Copy" or "Move." Then, select the destination directory and confirm the action.
That's it! These are some of the ways you can manage your website files using Directadmin web control panel. You can perform most of these operations with the built-in control panel file manager, or alternatively, you can remotely connect to your server and manage through command-line interface tools.
