微信聊天記錄可通過電腦備份長期保存，尤其是換手機(jī)或重置系統(tǒng)時。1. 使用微信內(nèi)置的備份與恢復(fù)功能：連接手機(jī)和電腦至同一Wi-Fi，打開電腦版微信，點(diǎn)擊左下角“備份與恢復(fù)”，選擇“備份聊天記錄至電腦”，按提示掃描二維碼并選擇需備份的聊天。2. 需要時可從備份中恢復(fù)：在電腦上選擇“恢復(fù)聊天記錄至手機(jī)”，掃描二維碼后確認(rèn)恢復(fù)，過程不會覆蓋現(xiàn)有記錄。3. 備份默認(rèn)存儲于電腦隱藏文件夾中，路徑可在備份設(shè)置中查看或更改，默認(rèn)路徑為C:\Users\YourUsername\AppData\Roaming\Tencent\WeChatBackup，刪除該處文件將清除備份，多設(shè)備使用時需注意備份位置。基本上就這些。

WeChat chat history can be kept for a long time if you back it up properly, especially when switching phones or doing a system reset. Here’s how to back up WeChat chat history to your PC in a straightforward way.

1. Use the Built-in Backup and Restore Feature

WeChat has a built-in function for backing up and restoring chat history via PC. This is the most reliable method officially supported by WeChat.

• Connect your phone and PC to the same Wi-Fi network.
• Open WeChat on your PC and click Backup & Restore in the left corner of the chat window.
• Choose Backup chat history to PC.
• Follow the instructions on your phone — you’ll need to scan a QR code and select which chats to back up.

This process may take a few minutes depending on how much data you have. It’s best to do this when you’re not in a hurry and your phone is fully charged or plugged in.

2. Restore from Backup When Needed

If you ever need to recover your chat history from the PC to your phone, the same tool works in reverse.

• Go to Backup & Restore again on PC.
• Select Restore chat history to phone.
• Scan the QR code that appears with your phone.
• Confirm the restore and wait for the process to finish.

Make sure not to close the app or disconnect during the transfer. Also, note that restored messages won’t overwrite existing ones — they’ll just be added to your current chat history.

3. Where Is the Backup Stored?

The backed-up data is saved in a hidden folder on your PC by default. You can check or change the storage path in the backup settings.

• On Windows, the default path is usually:
  C:\Users\YourUsername\AppData\Roaming\Tencent\WeChatBackup

You don’t need to open this folder unless you're troubleshooting or want to move backups manually. Deleting files here will remove your stored backups.

Backups are only as good as your access to them — so if you use multiple computers, remember to keep track of where your backups are saved.

基本上就這些。
