QQ talks about how to delete in batches.

It is said that batch (one-time) deletion is not supported, and only single deletion can be done manually.

How to delete a single conversation: log in to QQ space, select "Conversation" in the navigation bar to enter the conversation page, click "Conversation" to find the conversation to be deleted, and click "More =" to delete it.

Second, talk about comment deletion.

Log in to QQ space, click Talk = "Find the comment you want to delete =" Find the comment you want to delete, and click Delete. (as shown in the figure below)

Third, talk about deletion after being forwarded.

After the temporary QQ space conversation is forwarded, deleting the original text will not affect the forwarded content. If you want to delete this message completely, you need to contact the forwarder to delete it.

There are batch deletion software on the Internet, but the security is not high. It is recommended not to use it!
