What is .TDB file?
Cache file generated on SD cards used in Android phones and tablets; contains small versions or "thumbnails" of images saved on the card; provides a more efficient way to browse through the images on the card since the device does not have to load each full size image.
The Android thumbnail file is generated automatically when an SD card containing images is loaded on an Android device. It is typically named SThumbDB.tdb and is not meant to be opened manually. The file is often hidden, but may be displayed if hidden files are viewable. It may also appear if you mount the SD card on a computer or other non-Android device.
Common TDB Filenames:
SThumbDB.tdb - the default filename given to automatically generated thumbnail cache files.
