ASP FSO文件操作函数代码（复制文件、重命名文件、删除文件、替换字符串）

fso文件（file）对象属性
datecreated 返回该文件夹的创建日期和时间
datelastaccessed 返回最后一次访问该文件的日期和时间
datelastmodified 返回最后一次修改该文件的日期和时间
drive 返回该文件所在的驱动器的drive对象
name 设定或返回文件的名字
parentfolder 返回该文件的父文件夹的folder对象
path 返回文件的绝对路径，可使用长文件名
shortname 返回dos风格的8.3形式的文件名
shortpath 返回dos风格的8.3形式的文件绝对路径
size 返回该文件的大小（字节）
type 如果可能，返回一个文件类型的说明字符串
fso文件（file）对象方法
fso文件对象方法 用途
copyfile 拷贝一个或者多个文件到新路径
createtextfile 创建文件并且返回一个textstream对象
deletefile 删除一个文件
opentextfile 打开文件并且返回textstream对象，以便读取或者追加

重命名文件：

function rename(sourcename,destname)
dim ofso,ofile
set ofso=server.createobject("scripting.filesystemobject")
set ofile=ofso.getfile(server.mappath(sourcename))
ofile.name=destname
set ofso=nothing
set ofile=nothing
end function

删除文件：

function fsodel(filename)
dim fso,f
set fso = server.createobject("scripting.filesystemobject")
f=server.mappath(filename)
if fso.fileexists(f) then
fso.deletefile f,true
end if
set f = nothing
set fso = nothing
end function

替换文件中的字符串:

function fsoreplace(filename,target,repstring)
dim objfso,objcountfile,filetempdata
set objfso = server.createobject("scripting.filesystemobject")
set objcountfile = objfso.opentextfile(server.mappath(filename),1,true)
filetempdata = objcountfile.readall
objcountfile.close
filetempdata=replace(filetempdata,target,repstring)
set objcountfile=objfso.createtextfile(server.mappath(filename),true)
objcountfile.write filetempdata
objcountfile.close
set objcountfile=nothing
set objfso = nothing
end function
