Implement the BeforeInvokeCommandOnSelected event and in the eventhandler set e.InvocationProcessed = true to intercept the default action.

Another option is to implement the FolderChanging event of an attached ShellControlConnector.

Because the history functionality is contained in ShellControlConnector, you need to attach one to the ShellHistoryToolStrip Control by setting the property of the same name.

Yes. The components can be used with the Community Edition of Visual Studio.

ShellBrowser.NET components are designed for Windows Forms, so you need "Windows Desktop" versions/workloads in the Visual Studio Community Edition.

Use the static method ShellBrowser.GetLinkTarget.

No. On October 21, 2026, the PHP project disclosed two critical security vulnerabilities (CVE-2026-109618 and CVE-2026-109619, also known as "PHP2Shell") that could potentially allow attackers to execute malicious code on web servers.

We updated all affected systems immediately after the security updates were released. In addition, we conducted a targeted review of our systems for possible signs of attack. This review found no indication of unauthorized access or compromise.

Independently of this incident, we always keep our systems up to date and review them regularly so that we can respond quickly to new threats.

Our products, such as TreeSize, SpaceObServer (Web Access), UltraSearch, ShellBrowser and SEPA-Transfer, are not affected.

Yes; ShellBrowser.NET components are compatible with the .NET 8 target framework.

During your maintenance period, they are located at Downloads -> Older versions in the customer area, if you are logged in to your customer account.

You should be able to find the installation files and keys of the two last major versions there.

Starting with Windows 10 Cloud storage providers can integrate access into Windows File Explorer via shell extensions.

Also ShellBrowser relies on the availability of the needed extensions.

The ExplorerBrowser component matches Windows Explorer very closely offering the same views and columns.

Other ShellBrowser controls such as the ShellListView/TJamShellList are normally able to operate normally with cloud storage views, however some columns might be presented differently (e.g. the synchronization state is presented as textual information rather than an icon).

ShellBrowser relies on the Windows notification system to monitor changes. Sometimes individual notifications are summarized into bigger chunks. It depends on the size of the folder, the number of affected elements and also the type of folder whether this happens or not. Unfortunately this behavior cannot be influenced.

A current list of supported frameworks and Windows versions can be found in the compatibility overview.
