What is a .THUMBNAILS file?
The file extension .THUMBNAILS refers to a special type of folder found on some Android devices. This folder is usually hidden and located in the sdcard/DCIM directory, which is the default storage location for images and videos captured by the device's camera. The primary purpose of the .THUMBNAILS folder is to help the Android Gallery app load images faster. It does this by storing smaller, preview versions of images in files known as .THUMBDATA files.
Inside the .THUMBNAILS folder, you might find files with names like .THUMBDATA3--1967290299 and .THUMBDATA3-1763508120. These files contain data about the thumbnail images, such as their properties and indexing information, which allows the Gallery app to quickly display previews of images without having to load the full-size files.
To view or manage the contents of a .THUMBNAILS folder, you would typically use the Android Gallery app. This app is built into most Android devices and is designed to handle image viewing and management tasks, including accessing and utilizing the data stored in .THUMBNAILS folders. However, because this folder is hidden by default, you might need to adjust your file manager settings to show hidden files and folders if you wish to see the .THUMBNAILS folder using a file manager app.
