🗑️ Go – Delete File with os.Remove: Syntax, Safety & Examples (2025 Guide)

🧲 Introduction – Why Delete Files in Go?

In Go, you can delete a file using the os.Remove() function. Whether you’re cleaning up temp files, removing logs, or deleting user uploads, file removal is simple and effective with built-in tools from the os package.

🎯 In this guide, you’ll learn:

• How to delete files using os.Remove
• Handle missing file errors gracefully
• Check if file exists before deleting
• Best practices for secure file deletion

✅ Example – Delete a File Using os.Remove

package main

import (
    "fmt"
    "os"
)

func main() {
    err := os.Remove("example.txt")
    if err != nil {
        fmt.Println("Error:", err)
    } else {
        fmt.Println("File deleted successfully.")
    }
}

📤 Output:

File deleted successfully.

✅ os.Remove() deletes the named file (or symbolic link) immediately.

---

🔒 Check If File Exists Before Deleting

if _, err := os.Stat("example.txt"); err == nil {
    err := os.Remove("example.txt")
    if err != nil {
        fmt.Println("Delete failed:", err)
    } else {
        fmt.Println("Deleted file successfully")
    }
} else {
    fmt.Println("File does not exist")
}

✅ Use os.Stat() to avoid trying to delete a file that’s not there.

---

🗂️ Delete Directory or File with os.Remove

os.Remove("temp.txt")      // Deletes a file
os.Remove("myfolder")      // Deletes empty directory only

❌ os.Remove() will not delete non-empty directories.

---

🧹 Remove All Files and Folders – os.RemoveAll

err := os.RemoveAll("tempdir")
if err != nil {
    fmt.Println("Error deleting folder:", err)
} else {
    fmt.Println("Directory deleted recursively")
}

✅ os.RemoveAll() deletes a path and everything under it recursively—use with caution.

---

⚠️ Handle Errors Like a Pro

Error Type	What It Means
file not found	File doesn’t exist
permission denied	Insufficient rights to delete
is a directory	Attempted to delete a folder with os.Remove

Use errors.Is(err, os.ErrNotExist) for precise error checking.

---

🧠 Best Practices

Tip	Why It Helps
✅ Use os.Stat() before Remove()	Avoid unnecessary errors
✅ Handle permission errors	Helps in multi-user apps or services
❌ Don’t use RemoveAll() blindly	Prevents accidental recursive deletions
✅ Log deleted file names	Useful for audit and debugging
