**一、删除文件夹及其下所有子目录和文件（目录树）**

include masm32rt.inc  
  
;SSSSSSSSSSSSSSSSSSSSSSSSSS  
.data  
 ;SSSSSSSSSSSSSSSSSSSSSSSSSS  
fileop SHFILEOPSTRUCT<>  
Dir db "C:\\Users\\Alex\\AppData\\Local\\Temp",0  
  
;SSSSSSSSSSSSSSSSSSSSSSSSSS  
.code  
 ;SSSSSSSSSSSSSSSSSSSSSSSSSS  
start:  
mov fileop.wFunc,FO\_DELETE  
mov fileop.pFrom, offset Dir  
mov fileop.fFlags,FOF\_NOCONFIRMATION  
invoke SHFileOperation, addr fileop  
invoke ExitProcess,0  
end start

**二、从文件说明符中获取文件名**

**方法一：用Windows API函数——PathFindFileName**

原型：PTSTR PathFindFileName( \_\_in PTSTR pPath);

详见：[http://msdn.microsoft.com/en-us/library/windows/desktop/bb773589(v=vs.85).aspx][http_msdn.microsoft.com_en-us_library_windows_desktop_bb773589_v_vs.85_.aspx]

**方法二：**

;data  
  
string1 db "C:\\Windows\\system32\\calc.exe",0  
  
(...)  
  
;proc  
  
ExtractFileName proc lpPath: DWORD  
mov esi, lpPath  
petla:  
mov al, \[esi\]  
inc esi  
test al, al  
jz koniec  
cmp al, '\\'  
jne petla  
mov edx, esi  
jmp petla  
koniec:  
ret  
ExtractFileName endp  
  
(...)  
  
;usage (result in edx - pointer to first character of a filename)  
  
invoke ExtractFileName, addr string1  
  
;show the result  
  
invoke MessageBox, 0, edx, 0, 0

**方法三：**

.386  
.model flat, stdcall  
option casemap:none  
include \\masm32\\include\\windows.inc  
include \\masm32\\include\\kernel32.inc  
include \\masm32\\include\\user32.inc  
includelib \\masm32\\lib\\user32.lib  
includelib \\masm32\\lib\\kernel32.lib

.data  
;SSSSSSSSSSSSSSSSSSSSSSSSSS

g\_szFS1 db "c:\\a\\a.txt", 0  
g\_szFS2 db "c:b.txt", 0  
g\_szFS3 db "c.txt", 0  
  
;SSSSSSSSSSSSSSSSSSSSSSSSSS  
.code
