ADS Application of switched data Stream in NTFS

NTFS is a common file system format for Windows. This format supports switched data streams (Alternate Data Streams, abbreviated ADS) features. This feature allows multiple file streams to use the same file name, making it easy for the system to manage and use files. In this way, a file name can contain one main file stream and multiple non-main file streams. Among them, the main file stream can be accessed directly by file name, while other file streams need to be accessed by "file name: file stream name".

For such files, the file manager can only see the main file stream, not the rest. In this way, you can hide one or more files in another file. For example, this mechanism is used to hide seeds in common pictures on the Internet. At the same time, many Trojans also use this mechanism to avoid the detection and killing of antivirus software.
