LOST.DIR Folder in device

What is LOST.DIR Folder?

Android system has a special program called File System Check that is similar to chkdsk utility in Windows and fsck in Linux. This utility creates a LOST.DIR folder in the device. LOST.DIR is a system folder created in the SD card directory to collect the corrupted data. This data is created when the process of copying data from or into SD card is interrupted due to shutting down the phone or pulling out the SD card. You can analogous this folder to Recycle Bin of the Windows OS. Data can be moved back to its original place from the recycle bin and so can be done with this folder. However, files are moved to recycle bin because of the action of a user by deleting and in LOST.DIR, files are moved because of some technical interruption and not because of the user intention.
