If you scroll through your Android phone’s File Manager, you will most likely encounter the lost.dir folder. And when you open it, there are a bunch of unknown files.

Some people think that it is an unnecessary folder. But it actually contains some important data that you may need. If you want to know the importance of the lost.dir folder, stay on this page.

Part 1: What Is Lost.Dir?

Not a lot of people know the purpose of the lost.dir folder found in an Android phone. Well, upon thorough research, we found out that it actually plays a vital role on our devices.

The lost.dir works the same as the Recycle Bin on computers. It collects all the corrupted data that are created when an error occurs on your phone such as:

• Application Malfunction
• Phone System Error
• Battery Failure
• Improper Removal of SD Card
• OS Update Errors

When your phone shuts down due to these errors, all the data from apps and features that are wiped out, corrupted, or deleted will automatically be stored on the lost.dir folder. For example, if you notice that a certain file was corrupted after an error, it will most likely be stored on the lost.dir folder.

Deleting the lost.dir folder is not a big deal if you have no intention of recovering or fixing the affected data or they are not relevant to you. But if you wish to restore them, you will need a lost.dir recovery.
