WinDirStat Keeps SNG: A Comprehensive Guide to Resolving This Issue

Introduction

WinDirStat, an open-source disk space analyzer, is renowned for its ability to provide a comprehensive visualization of disk usage. However, some users have reported encountering the enigmatic "SNG" file type, which often consumes a significant portion of storage space. This article aims to shed light on this issue and equip users with effective solutions to resolve the "WinDirStat Keeps SNG" problem.

What is SNG?

SNG is an acronym for Secure Name Generation, a Windows feature designed to enhance file security. It generates a unique identification number (USN) for each file on the system, which is stored in a separate $SNG file. This file is typically located in the root directory of each volume and contains a record of all USNs assigned to files.

Why WinDirStat Keeps SNG?

By default, WinDirStat displays all files present on the system, including system files and hidden files. The $SNG file, being hidden by default, is not visible to users unless WinDirStat is configured to show hidden files. This behavior can lead users to believe that WinDirStat is keeping a large number of SNG files, which is not accurate.

How to Resolve the Issue

There are several methods to resolve the "WinDirStat Keeps SNG" issue:

Introduction

3. Use a Different Disk Analyzer:

If you prefer not to modify WinDirStat's settings, you can consider using a different disk space analyzer that excludes system files by default, such as TreeSize Free, SpaceSniffer, or WizTree.

Additional Information

1. Impact of SNG Files on Performance:

$SNG files are generally small in size and have minimal impact on system performance. However, in rare cases, a large number of USNs can lead to a slight decrease in system speed.

2. Security Considerations:

SNG files do not contain any sensitive user data and are necessary for maintaining file security. Deleting the $SNG file can compromise the integrity of the file system and is not recommended.

Tips and Tricks

To quickly locate the $SNG file, open File Explorer and enter $SNG in the search bar.
Use the command dir /a /s $SNG in Command Prompt to display all $SNG files on the system.
Consider disabling USN tracking for non-essential folders to reduce the size of the $SNG file.

FAQs

1. Why is the $SNG file so large?

The $SNG file grows in size as more files are created and modified on the system. File fragmentation can also contribute to the file's size.

2. Can I delete the $SNG file?

No, it is not recommended to delete the $SNG file as it can compromise file security.

3. How can I reduce the size of the $SNG file?

Disabling USN tracking for non-essential folders and defragmenting the file system can help reduce the size of the $SNG file.
