How to Find Locked Dash Cam Videos on Your Memory Card

What locked videos are and why they are separate

A dash cam records continuously, and on a full card the oldest normal clips are overwritten. That is how loop recording works. If you press the manual save button or the G-sensor detects a sudden impact, the camera protects the current clip so it is not erased. The protected clip becomes a locked video or event video, separate from the everyday loop files.

Motor vehicle crashes are a leading cause of death, so a dash cam's protected clips can be valuable evidence. Because locked clips are meant to survive, the camera makes a copy or moves them to a different area. That separate location is why the file is not mixed in with the normal recordings.

Where the locked folder is on the memory card

Dash cams organize files in folders. On many models, normal clips live in a DCIM or VIDEO folder, while protected clips go into a folder named EVENT, LOCK, RO, PROTECT, or 911. Some brands use a subfolder such as DCIM/EVENT or DCIM/LOCK. If you want to understand the folder layout, the file system article explains the common patterns.

When you remove the memory card and put it in a computer, open each folder and look for video files. The locked clips are usually marked with an icon or a file name that includes "event" or "lock". If your camera does not create a separate folder, it may add a protection flag to the file name, which is why the file still appears in the normal list but is not overwritten.

Card storage is also worth checking: a card that is close to full may not have room for locked clips, or it may show a card full message. See the memory card storage article for more on capacity and choosing the right card.

Find locked clips on the camera screen

Use the camera's playback or gallery mode. Look for an icon or tab labeled Event, Locked, Protected, or Emergency. Some models have a separate list for normal and event files, and others let you press the manual save button while a clip is highlighted to lock it.

If you see a locked clip you need, play it on the camera first. On a small screen you can check the basic content, then connect the camera to a computer or use the app to transfer it. The video playback article explains the common ways to play and export dash cam files.

Find locked clips on a computer or phone

Connect the memory card to a computer with a card reader, or connect the camera through the supplied cable. Open the card's root directory and look for the locked folder. Copy the whole file or just the clip you need, then unlock or delete it from the camera so it does not fill the card.

For a Wi-Fi dash cam, open the companion app and look for an album called Event, Locked, or Protected. Many apps let you download the clip to your phone, and some have a delete or unlock option. The Wi-Fi apps article covers common app tasks.

If locked clips do not show up

If you cannot find a locked clip, first make a test clip. Press the manual save button while recording, stop the camera, and then look for that clip. If it appears in a particular folder, that is where future locked clips will be stored. Some cameras label the folder only after the first event, so an empty card may not show the folder until you save something.

If the clip exists but will not play, the video file may be corrupt or the player may not support the format. Try playing it on the camera, or use a media player that handles the file type. The locked files won't play article has specific steps, and the recover footage from a corrupt card article explains what to do when the card will not open normally.

How to unlock or delete locked videos

After you copy the clip you need, you can unlock it from the camera so it enters normal loop rotation. The exact menu names vary: look for Unlock, Delete, or Format. Some cameras let you press the manual save button while a protected clip is highlighted to remove the lock. On others, the setting is under Playback, Event, or File Manager.

If you want a clean start, formatting the card removes all protected and normal files. Back up anything you need first. After formatting, set the camera to use the card and make a test save to confirm the event folder is created again. The format microSD card article walks through the process.

Manage locked files to keep your card healthy

Locked clips do not get overwritten, so they can accumulate. If the card fills with event videos, some cameras stop recording or refuse to save new locked clips. Check the event folder every few weeks, copy anything you want to keep, and delete the rest.

Some cameras let you unlock a clip by selecting it in playback and pressing the save button again. Others can only clear protected files through formatting, so make sure you have backed up important clips before formatting. The event files overwritten article explains how cameras handle protected files and why they can still disappear in some situations.

What to pick for your use

Questions

Why can't I find a locked video in the normal list?

Locked clips are stored in a separate protected folder. Use the camera's playback filter or browse the memory card for a folder named EVENT, LOCK, RO, or PROTECT.

Does unlocking a file delete it?

No. Unlocking removes protection so the file behaves like normal loop footage and can eventually be overwritten. Copy the clip before you unlock it if you want to keep it.

Can I recover a locked video after formatting the card?

Usually not with built-in tools. Formatting erases all folders. If the card has not been reused, third-party recovery software may help, but success is not guaranteed.

Where should I look if my dash cam has an app?

Open the app's album or file list and look for Event, Locked, or Protected. Most apps let you download the clip to your phone for safekeeping.

Why are my locked files not playing on the computer?

The codec or file extension may not be recognized. Try the camera's own playback, or use a player that supports MP4, MOV, or TS and H.264 or H.265. The video playback article has more details.

Should I leave locked files on the card?

Only if you still need them. Locked clips take up space and can prevent new recordings or new event saves. Download important clips and delete or unlock the files periodically.
