This event is fired when the storage needs to be deleted.

[Pascal]
TSolFSDeleteFileEvent = procedure( Sender : TObject; const FileName : WideString; var Result : LongInt) of object;

[DLL]
typedef Error (__stdcall *SolFSDeleteFileFunc)( LongWord UserData, PWideChar FileName);

[C++ (DLL/Lib)]
typedef Error (__stdcall *SolFSDeleteFileFunc)( LongWord UserData, PWideChar FileName);

[C++ (VCL)]
typedef void (__closure *TSolFSDeleteFileEvent)( System::TObject* Sender, const WideString FileName, Error& Result);

[C++ (.NET)]
public __delegate void SolFSDeleteFileEvent( SolFSStorage* Sender, System::String* FileName, Int32 __gc &Result);

[C#]
public void SolFSDeleteFileEvent( SolFS.SolFSStorage Sender, string FileName, ref int Result);

[VB.NET]
Sub SolFSDeleteFileEvent( ByVal Sender As SolFS.SolFSStorage, ByVal FileName As String, ByRef Result As Int32);

Sender - reference to the class that called the delegate/event handler.
FileName - the name of the storage as passed to SolFSStorage.Create constructor.
Result - out parameter (return value for DLL) is where the application places the result of the operation. If you are working with file system, Win32 error code is a good candidate for placing to Result parameter. Otherwise you can use any other error codes, just be sure that 0 means success.
[DLL] UserData - application-defined parameter which is specified when creating the storage and passed back to callback function.

The event is fired when the storage file must be deleted from media.
