The Go language provides two methods to clear file contents: using io.Seek and io.Truncate, or using ioutil.WriteFile. Method 1 involves moving the cursor to the end of the file and then truncating the file, method 2 involves writing an empty byte array to the file. The practical case demonstrates how to use these two methods to clear content in Markdown files.

Reading and writing files safely in Go is crucial. Guidelines include: Checking file permissions Closing files using defer Validating file paths Using context timeouts Following these guidelines ensures the security of your data and the robustness of your application.
