Question

我需要开发一个脚本来比较文件夹的大小，该文件夹保存在文本文件中。如果文件夹大小增加，则应提示文件夹大小增加。

Answer 1

使用VBScript监控目录

Option Explicit
Dim fso,Message,Message2,Msg,intInterval,strDrive,strFolder,strComputer,objWMIService,strQuery
Dim colEvents,objEvent,objTargetInst,objPrevInst,objProperty,ws,LOG_FILE_PATH,LogFile,Chemin,MonTableau
Set fso = CreateObject("Scripting.FileSystemObject")
Set ws = CreateObject("WScript.Shell")
strComputer = "." 
Chemin = Parcourir_Dossier()
MonTableau = Split(Chemin,"\")
LogFile = MonTableau(UBound(MonTableau)) & ".log"
LOG_FILE_Path = ws.ExpandEnvironmentStrings("%AppData%") & "\" & LogFile
intInterval = "2"
'****************************************************************************************************

    Dim ws,objFolder,Copyright
    Copyright = "[ © Hackoo © 2014 ]"
    Set ws = CreateObject("Shell.Application")

    & Copyright,1,"c:\Programs")
    If objFolder Is Nothing Then
        Wscript.Quit

    Parcourir_Dossier = objFolder.self.path

Answer 2

试试这样：

Folder = "c:\your\path\tata"
File = "c:\your\file\containing\the\value.txt"
set objFSO = CreateObject("Scripting.FileSystemObject")
set fileRead = objfso.OpenTextFile(file, 1) 
content = fileRead.Readline
FileRead.close
set objFolder = objFSO.GetFolder(Folder)
if objFolder.Size > Clng(content) Then  Wscript.Echo "The Folder size [" & ObjFolder.size & "] is bigger then [" & content & "]"

如果您需要更新文本文件中的值。

Folder = "c:\your\path\tata"
File = "c:\your\file\containing\the\value.txt"
set objFSO = CreateObject("Scripting.FileSystemObject")
set fileRead = objfso.OpenTextFile(file, 1)
content = fileRead.Readline
FileRead.close
set objFolder = objFSO.GetFolder(Folder)
set fileWrite = objfso.OpenTextFile(file, 2)
FileWrite.writeline(ObjFolder.size)
FileWrite.close
if objFolder.Size > Clng(content) Then  Wscript.Echo "The Folder size [" & ObjFolder.size & "] is bigger then [" & content & "]"

VB脚本用于比较文件夹大小与其先前存储在文本文件中的大小
