It is really painful to open a file (using the open dialog) in Windows XP if the directory that contains the file has a lot of files. Ever had to find a file in the Windows folder or another large folder like system32?

The freeware Windows Multienhancer enlarges the dialog box that displays the files and adds additional information like file size and the date the file was modified to it. This is done by patching the Comdlg32.dll file on the system that holds the information. Note that this works only if the version of the dynamic link library is supported by Windows Multienhancer.

To check if the dll is supported right-click it in the windows\system32 folder and selected properties. Select the version tab and compare the version number that is displayed to the versions that are patchable by Windows Multienhancer.

If the file can be patched a new size for the dialog box will be automatically suggested but you can change it if you like.

The freeware can also patch annoying message boxes in Outlook Express and Internet Explorer. Four messages are removed in Outlook Express, those are:

  1. You are currently working offline. Would you like to go online now?
  2. No connection to the internet is currently available.... Click Try Again to attempt to connect ?
  3. Would you like to hangup the modem before going offline?
  4. You have unsent messages in your Outbox. Do you want to send them now?

Finally two messages can be removed in the Internet Explorer, those are:

  1. The webpage you requested is not available offline. To view this page click Connect
  2. No connection to the internet is currently available..... Click Try Aagain to connect.

To do this it has to patch the files Comdlg32.DLL, Wininet.DLL, Msoe.DLL.

Update: Please note that while the program may be useful for earlier versions of the Windows operating system like Windows XP, it is not necessary anymore for newer versions of Windows as you can resize the window of the open file dialog window natively in those operating system. To do that, simply move the mouse cursor to the border of the window, click and hold down the left mouse button and drag and drop it to resize the window.

Update 2: The program is no longer available and not needed anymore on newer versions of Windows as it is possible to change the size of the open or save box.
