AlternateStreamView 64bit 1.55

AlternateStreamView is a small utility that allows you to scan your NTFS drive, and find all hidden alternate streams stored in the file system. After scanning and finding the alternate streams, you can extract these streams into the specified folder, delete unwanted streams, or save the streams list into text/html/csv/xml file.

System Requirements
This utility works on any version of Windows starting from Windows 2000 and up to Windows 10. Both 32-bit and 64-bit systems are supported.

Known Issues
It seems that starting from Windows 7, the standard 'Open With' dialog-box of Windows stopped working with alternate streams, and thus the 'Open Selected Stream With...' option provided by AlternateStreamView also doesn't work...

Versions History

Version 1.55:

Fixed bug: AlternateStreamView failed to remember the last size/position of the main window if it was not located in the primary monitor.
You can now send the data to stdout by specifying empty string as filename, for example:
AlternateStreamView.exe /scomma "" | more

About Alternate Streams in NTFS File System
NTFS system has a feature that allows you to add multiple streams in addition to the main file stream. When you open or view the file, only the main file stream is visible, while other additional streams are hidden from the user.

Here's 3 examples of alternate streams usage in Windows operating system:

Favorites of Internet Explorer: When You add a Web site link into your 'Favorites', a .url file containing the url and description is created. However, if the Web site also have an icon (favicon), the icon is saved as alternate stream for the same url file. The stream name of the icon is :favicon:$DATA
Downloaded files of Internet Explorer: When you download and save a file with Internet Explorer, it automatically add a zone information for the saved file. This zone information is used for identifying the file as downloaded file from the Internet. The stream name in this case is :Zone.Identifier:$DATA
Summary information of files: When you right-click on a file in Explorer and go to the 'Summary' tab, you can add summary information for the file, like title, subject, author, and so on. This summary information is also saved into alternate stream. The stream name in this case is SummaryInformation:$DATA.

In addition to the legitimate usage of alternate streams, this technique may also be used by Viruses/Trojans/Spywares for saving data and hiding it from the user.

Using AlternateStreamView
AlternateStreamView doesn't require any installation process or additional DLL files. In order to start using it, simply run the executable file - AlternateStreamView.exe
After running it, choose the drive or folder that you wish to scan, and click Ok. AlternateStreamView will scan the selected folder, and then it'll display all alternate streams found in the selected drive/folder. After the scan is finished, you can select one or more alternate streams, and then delete them ('Delete Selected Streams' option), or copy them into a folder that you choose ('Export Selected Streams To...').

Command-Line Options
/FolderPath <Folder> Specifies the folder to scan
/ScanSubfolders <0 | 1> Specifies whether to scan the subfolders under the folder specified in /FolderPath
0 = No, 1 = Yes.
/SubFolderDepth <Depth Value> Specifies the folder depth to scan when ScanSubfolders is 1. If 0 is specified, the folder depth is unlimited.
/ShowZeroLengthStreams <0 | 1> Specifies whether to show zero length streams. 0 = No, 1 = Yes.
/Filename <filename> Loads the specified filename into AlternateStreamView.
/stext <Filename> Save the list of alternate streams into a regular text file.
/stab <Filename> Save the list of alternate streams into a tab-delimited text file.
/scomma <Filename> Save the list of alternate streams into a comma-delimited text file (csv).
/stabular <Filename> Save the list of alternate streams into a tabular text file.
/shtml <Filename> Save the list of alternate streams into HTML file (Horizontal).
/sverhtml <Filename> Save the list of alternate streams into HTML file (Vertical).
/sxml <Filename> Save the list of alternate streams into XML file.
/sort <column> This command-line option can be used with other save options for sorting by the desired column. If you don't specify this option, the list is sorted according to the last sort that you made from the user interface. The <column> parameter can specify the column index (0 for the first column, 1 for the second column, and so on) or the name of the column, like "Stream Name" and "Filename". You can specify the '~' prefix character (e.g: "~Stream Size") if you want to sort in descending order. You can put multiple /sort in the command-line if you want to sort by multiple columns.

AlternateStreamView.exe /shtml "f:\temp\alt.html" /sort 2 /sort ~1
AlternateStreamView.exe /shtml "f:\temp\alt.html" /sort "Stream Size"
/nosort When you specify this command-line option, the list will be saved without any sorting.

AlternateStreamView.exe /FolderPath "f:\temp" /ScanSubfolders 1 /SubFolderDepth 1 /shtml "f:\temp\streams.html"

Translating AlternateStreamView to other languages
In order to translate AlternateStreamView to other language, follow the instructions below:

Run AlternateStreamView with /savelangfile parameter:
AlternateStreamView.exe /savelangfile
A file named AlternateStreamView_lng.ini will be created in the folder of AlternateStreamView utility.
Open the created language file in Notepad or in any other text editor.
Translate all string entries to the desired language. Optionally, you can also add your name and/or a link to your Web site. (TranslatorName and TranslatorURL values) If you add this information, it'll be used in the 'About' window.
After you finish the translation, Run AlternateStreamView, and all translated strings will be loaded from the language file.
If you want to run AlternateStreamView without the translation, simply rename the language file, or move it to another folder.
