File name may get garbled or FTP folder error may occur when uploading a file including Japanese text to an FTP site by using the FTP function of Windows Explorer.

When a file including Japanese text is uploaded to an FTP site by using the FTP function of Windows Explorer of Microsoft Windows OS, the file name of the uploaded file may get garbled or the following FTP folder error may occur.

Even though the FTP function of Windows Explorer negotiates with the FTP server, characters are not correctly converted when UTF-8 encoding is used, causing the aforementioned symptom.

To avoid this symptom, disable the UTF-8 setting in an FTP server.

1. Open Server Manager.
2. Click Roles > Web server (IIS) > Internet Information Services (IIS) Manager.
3. In the Connections pane, click to expand the appropriate server name > Sites > the appropriate site name.
4. Right-click the appropriate site name and click Manage FTP site > Advanced Settings.
5. In the Advanced Settings dialog box, set Enable UTF-8 to False (the default value is True).
6. Click the OK. button.
7. Right-click the appropriate site name and click Manage FTP site > Restart.

Microsoft is researching this problem and will post more information in this article when the information becomes available.

Procedure for Recreating the Problem

1. In the FTP Server, enable UTF-8. If you are using Internet Information Services 7.5 (IIS 7.5), use the advanced settings in the properties of the FTP site.
2. In the Address box of Windows Explorer, enter "ftp://FTP server name".
3. Upload a file including Japanese text.

Result

The file name of the uploaded file gets garbled.
