Category: Windows 🠪 Sercurity Data Streams - Super Hidden Files | May 24, 2022 | Data Streams in NTFS allow files to have hidden content that is harder to see.
You can see how much space is used in Windows Explorer, going to properties for a file/folder. The Size field is the main file/folder. The Size On Disk includes the main file as well as any alternate data streams.
Create a data stream from command prompt: notepad notes.txt:test
To view them in command prompt, use: dir /r
Copy a file into a data stream:
type picture.jpg > notes.txt:pic1
Notes:
Deleting the main file will delete alternate data stream.
Copying to a different file system (such as FAT32) will warn you that some properties can't be copied (the alternate data streams).
Nirsoft utility "AlternateStreamView" lets you scan for them.
