Increasing Maximum Number Of Simultaneous Connections Beyond 10 In FileZilla

FileZilla is an FTP client that is commonly used to access files remotely. By default, the maximum number of simultaneous connections that you can have using FileZilla is 10. However, this can be changed by editing an XML file directly with a text editor.


For the best results, we recommend that the maximum number of simultaneous connections is set to the same value on the server that you’re connecting to. Selecting 8 or lower and ending your FTP connection to the server once you are done connecting is highly suggested if you are receiving a 421 error.


How Do I Add More Than 10 Simultaneous Connections In FileZilla?

You can increase the maximum number of simultaneous connections by performing the following steps. Please ensure that FileZilla is open at this time.


Step 1:  Select the File tab from the navigation bar located at the top of the FileZilla client where a drop down will appear when you click

Step 2:  From the dropdown menu, select the Site Manager option

Step 3:  From the Site Manager menu that’s now open, click on the “New Site” button

Step 4:  Fill in the required FTP login information, such as Host, Port, Protocol, Logon Type, User, and Password…A brief explanation of these values are as follows:


    • Host: Your domain name or IP address
    • Port: The default FTP port is 21, and the default ssh port (for SFTP) is 22
    • Protocol: FTP or SFTP
    • Encryption: This should be set to “Use explicit FTP over TLS if available”
    • Logon Type: Typically this should be set to Normal
    • User: The username that you’re using to connect, this can be root or your cPanel username
    • Password: The FTP password for the user you’re using to connect


Step 5:  Once you’ve entered in the FTP login information click the OK button

Step 6:  On your computer, open a text editor of choice as the Administrator or equivalenta. Note: I will be using Notepad ++ as the Administrator (This can be done by right clicking the application and selecting Run as administrator from the pop up menu)

Step 7:  Open the sitemanager.xml file within your text editor, located typically within your %AppData% directory.  This can be located within (C:)Users<username>AppDataRoamingFileZillasitemanager.xml



Sometimes your AppData directory can be hidden within the user directory.  If AppData is not displayed, proceed into your File Manager and select view at the top, and Options >> Change Folder and Search Options.

Also, searching for “%AppData%” (no quotes) within your computer should produce the correct files without showing hidden files.
