How to prevent Android from creating LOST.DIR on SD card? After the phone restarts, there is a LOST.DIR folder created on the external SD card. Is it possible not to create this folder if nothing is lost?
LOST.DIR is just a storage space (directory) for files that were recovered upon boot. You can safetly remove it with no problems. The sysytem keeps it just in case you want to get your recovered currupted files back.

A quick google search yielded:


LOST.DIR - what is it?


As for preventing it from being created, just prevent the SD card from becoming corrupted. Here are some things to keep in mind while using an SD card:


Always eject before removal
Never remove while files are being modified
Never remove from Android device while device is on


If you have your device connected to the computer, the SD card will usually automatically mount itself on the computer. Remember to eject it before disconnecting the device.



This thread has a ton of good info. Basically the gist of it is, if you are following all of the precautions to keep the SD card from getting corrupted (ejecting before removal, ect...) then the SD card is partially incompatible with your device. If you move to a higher class SD card, the problem usually goes away on its own.
