How To Recover LOST DIR Files

Wondering what LOST.DIR is? And what does it do?

LOST.DIR, by its name, as you can understand that it means Lost Directory. This Folder can be found on SD Card (Memory Card) or the Phone’s Internal Storage. But it is commonly found on SD Card.

Now let’s understand what it really is?

This Folder stores those files whose extensions are lost and without an extension that file is useless. Every file has its own extension. Let’s take Image for an example its extensions are .png, .jpg, .jpeg, .gif, .heic, etc. Likewise for Audio Files the extensions are .mp3, .ogg, .m4a, .ac3, .aac etc. For videos the extensions are .mp4, .mkv, .avi, .ts, .3gp etc.

These were some of the extensions of the respected files.

To recover these files, you just have to rename and add an extension to the end of the name, then you have to open that file and check it to make sure if it works properly or not. If the file is not opening, then that means you have added the wrong extension to the file, and the extension does not match the file. So, rename and change the extension of the file and check the file again. Continue doing this until you get the correct one.

But wait, doesn't it seems to be a long process? It actually is a lengthy process. So follow this next method. I will provide you an App, with that you can recover your files instantly, and it will do the job for you. It is a premium version app for free but, if you download the same App from the play store, you have to pay for the App, and it is not guaranteed that the Play Store version will do the job correctly.
