Shell Folder Unit

Contents

Description

This unit provides various components, classes and routines for handling Windows shell folders. It contains:

  • A component that provides information about a specified special shell folder.
  • A class that enumerates all the special shell folders.
  • Routines to manipulate special shell folder information.
  • A component that encapsulates the Windows Browse for Folder dialogue box.
  • A property editor that enumerates special shell folder identifiers.

For full details please see the online documentation.

Compatibility

The Shell Folders Unit has been tested on Delphi 7 to XE4 Windows compilers (except Delphi 2005) and the Delphi XE2 to XE4 64 bit compilers. The unit is thought to compile on compilers back to Delphi 4, but that is not guaranteed.

The unit is for use with the VCL only: it is not compatible with FireMonkey.

.NET and non-Windows platforms are not supported.

Some features require Delphi 6 and later and are not implemented when compiled with earlier compilers.

Installation

The Shell Folders Unit, its components and associated property editors, documentation and demo program are supplied in a zip file. Before installing you need to extract all the files from the zip file, preserving the directory structure. The following files will be extracted:

  • PJShellFolders.pas – classes, routines and component source code.
  • PJShellFolders.dcr – component palette glyphs.
  • PJShellFoldersDsgn.pas – property editors and component registration source code.
  • README.md – this file.
  • CHANGELOG.md – change log.
  • MPL-2.txt – the Mozilla Public License v2.0.
  • Documentation.URL – short-cut to the Shell Folders Unit's online documentation.

In addition to the above files you will find the source code of a demo project in the Demo sub-directory.

You can now install the components into the Delphi IDE. To do this, the files PJShellFolders.pas, PJShellFolders.dcr and PJShellFoldersDsgn.pas should be added to a design time package. If you need help doing this see here.

Demo Program

A demo program with associated explanatory notes is included in the download. The demo lists and provides information about all the special shell folders supported by the unit.

Delphi 7 or later is required to compile the demo, which is compatible with Windows 32 and 64 bit compilers.

For more information see the demo read-me file.

Update History

A complete change log is provided in CHANGELOG.md that is included in the download.
