How to Set WinSCP to Chinese and Integrate with PuTTY
WinSCP is an open-source graphical SFTP client used in the Windows environment. Its main function is to securely copy files between local and remote computers and directly edit files. PuTTY, on the other hand, is an open-source, lightweight SSH tool. Together, they form a perfect combination.

I have to complain about the Xshell tool I've been using for a long time. Recently, a backdoor was discovered—not a vulnerability, but a backdoor. Even the official download was compromised, let alone third-party websites. It's really worrying. All links provided in this article are official addresses, and I recommend this method as it is relatively safer.
Download WinSCP
Official download address: WinSCP Download
WinSCP supports both portable and installer versions. Please download and install it via the link above.
Set Chinese Language
When you start WinSCP, the interface is in English, which is inconvenient for those not fluent in English. The official website provides a Chinese language pack. Visit: WinSCP Language Pack, find Simplified Chinese, and download it.

Extract the language pack to the WinSCP installation directory and restart WinSCP. Note: You must connect to a host first before opening the settings. Press the shortcut key Ctrl + Alt + P to open the following interface, set it to Simplified Chinese, and restart WinSCP to see the Chinese interface.

Integrate with PuTTY
Once WinSCP is integrated with PuTTY, you can quickly open an SSH terminal via PuTTY. Press the shortcut key Ctrl + Alt + P to open Settings > Integration > Applications, and set the PuTTY client path as shown in the screenshot below.

After integrating PuTTY, you can press Ctrl + P to quickly open PuTTY, or click the button shown in the image below.

Summary
WinSCP is used for uploading and downloading files, while PuTTY connects to the SSH terminal to manage servers. The combination of the two is perfect. Third-party websites offer versions like "WinSCP Chinese Edition," but I strongly do not recommend them. It is safer to download from the official source.
