I understand that you are asking for the file name to change from "CSGO 刀" to "CS:GO 刀". The file name typically refers to the name of the file that contains the custom map, and the file extension indicates the file format.

To change the file name and extension, you can follow these steps:
1. Open the "CS:GO 刀" file.
2. Remove the .bot extension from the file name.
3. Add .cs to the file name.
4. Save the file.
The new file name should now be "CS:GO 刀.cs".
