How to Delete Temporary Files in Mobile

🗑 How to Delete Temporary Files in Mobile (Android Guide 2026)

Is your mobile storage getting full?
Your phone may be filled with temporary files (TMP files, cache files, junk files).

In simple words:

Temporary files are small files created by apps to store short-term data.

Deleting them can free up storage and improve performance.

Let’s learn how to remove them safely.


📱 What Are Temporary Files?

Temporary files are created when:

  • You browse the internet

  • You use social media apps

  • You stream videos

  • You install apps

These files help apps load faster, but over time they take up space.

Examples:

  • Cache files

  • .tmp files

  • Log files

  • Residual app files


✅ Method 1: Clear App Cache (Safe & Recommended)

This is the safest way.

Steps:

1️⃣ Open Settings
2️⃣ Tap Apps
3️⃣ Select an app (like Chrome or Instagram)
4️⃣ Tap Storage
5️⃣ Click Clear Cache

⚠ Do NOT tap “Clear Data” unless necessary — it removes login info.


🚀 Method 2: Use Built-In Storage Cleaner

Most Android phones have built-in cleaning tools.

On Samsung:

Settings → Battery & Device Care → Storage → Clean Now

On Xiaomi / Redmi:

Security App → Cleaner → Clean Junk Files

On Realme / Oppo:

Phone Manager → Clean Storage

These tools safely delete temporary files.


📂 Method 3: Delete Temporary Files Using File Manager

1️⃣ Open File Manager
2️⃣ Go to Internal Storage
3️⃣ Look for folders like:

  • Temp

  • Cache

  • Downloads

  • DCIM (check unwanted files)

You can safely delete unnecessary .tmp files.


🌐 Method 4: Clear Browser Temporary Files

If you use Chrome:

1️⃣ Open Google Chrome
2️⃣ Tap 3 dots → Settings
3️⃣ Privacy → Clear Browsing Data
4️⃣ Select Cached Images & Files
5️⃣ Tap Clear Data

This removes internet temporary files.


📦 Method 5: Delete Temporary Files Using Google Files App

You can use:

Files by Google

Steps:
1️⃣ Open the app
2️⃣ Go to Clean tab
3️⃣ Tap “Clean Junk Files”
4️⃣ Confirm

This is one of the safest methods.


⚠ Important Tips

✔ Keep at least 20% storage free
✔ Don’t delete system folders
✔ Avoid unknown cleaning apps
✔ Restart phone after cleaning
