Antivirus Detection

> [!WARNING] > The utility might be flagged by antivirus software as suspicious. This is a false positive caused by our use of: > - COM interactions (for File Explorer tab management) > - Low-level keyboard & mouse hooks (for hotkey support) > > The tool is completely open source, and you can: > - Review the source code in this repository > - Build it yourself using Visual Studio > - Verify its safety and functionality

Adding to Windows Defender Exclusions

If Windows Defender is blocking the utility, you can add it to the exclusions list:

Open Windows Security
Go to Virus & threat protection
Click Manage settings under Virus & threat protection settings
Scroll down to Exclusions and click Add or remove exclusions
Click Add an exclusion and select Folder
Browse to the Explorer Tab Utility folder location

Alternatively, you can use PowerShell (Run as Administrator):

Add-MpPreference -ExclusionPath "PATH_TO_UTILITY_FOLDER"

ℹ️ Notes

> [!NOTE] > While this utility is optimized for best performance, some operations might experience delays due to limitations in Windows File Explorer itself: > - The File Explorer's tab interface lacks proper APIs for programmatic control > - Some operations in File Explorer are inherently laggy, especially with multiple simultaneous window operations > - Windows Shell doesn't expose all the necessary functionality for seamless tab management

Despite these Windows limitations, the utility implements the best possible solutions using available Windows APIs and COM interfaces.
