Question

我有一个bat脚本，其中获取文件夹中的所有文件，然后将此文件夹及其内容转换为一个RAR文件。此脚本还会在复制后添加当前日期，并将此文件移动到备份文件夹中。我打算每天通过Windows调度程序任务运行这个bat文件。

我的问题：

是否可以添加到此脚本中以删除备份文件夹中7天以前的所有rar文件？

for /f "delims==" %%D in ('DIR D:\scripts /A /B /S') do (  
"C:\Program Files\WinRAR\WinRAR.EXE"  a -agyyyy-MM-dd -r "c:\backup\scripts.rar" "%%D"  
)

就是这样......

我有一个非常相似的脚本（Visual Basic Script）。但是，您需要修改目录路径，文件扩展名（.RAR）和日期长度（在此示例中，＆gt; = 3将此设置为7）：

编辑1： 简单地复制＆amp;将其粘贴到新文本文件中，并将扩展名重命名为.vbs。

示例解决方案脚本：

On Error Resume Next   
Dim fso, folder, files, sFolder, sFolderTarget     
Set fso = CreateObject("Scripting.FileSystemObject")   

'location of the database backup files 
sFolder = "X:\Data\SQL_Backup\" 

Set folder = fso.GetFolder(sFolder)   
Set files = folder.Files     

'used for writing to textfile - generate report on database backups deleted 
Const ForAppending = 8 

'you need to create a folder named “scripts” for ease of file management &  
'a file inside it named “LOG.txt” for delete activity logging 
Set objFile = fso.OpenTextFile(sFolder & "\scripts\LOG.txt", ForAppending) 

objFile.Write "================================================================" &   VBCRLF & VBCRLF 
objFile.Write "                     DATABASE BACKUP FILE REPORT                " & VBCRLF 
objFile.Write "                     DATE:  " &    FormatDateTime(Now(),1)   & "" & VBCRLF 
objFile.Write "                     TIME:  " &    FormatDateTime(Now(),3)   & "" & VBCRLF & VBCRLF 
objFile.Write "================================================================" & VBCRLF  

'iterate thru each of the files in the database backup folder 
 For Each itemFiles In files  
'retrieve complete path of file for the DeleteFile method and to extract  
'file extension using the GetExtensionName method 
 a=sFolder & itemFiles.Name 

'retrieve file extension  
b = fso.GetExtensionName(a) 
   'check if the file extension is BAK 
   If uCase(b)="BAK" Then 

       'check if the database backups are older than 3 days 
       If DateDiff("d",itemFiles.DateCreated,Now()) >= 3 Then 

           'Delete any old BACKUP files to cleanup folder 
           fso.DeleteFile a  
           objFile.WriteLine "BACKUP FILE DELETED: " & a 
       End If 
   End If 
Next   

objFile.WriteLine "================================================================" & VBCRLF & VBCRLF 

objFile.Close 

Set objFile = Nothing 
Set fso = Nothing 
Set folder = Nothing 
Set files = Nothing

我希望有所帮助。

查看一个名为forfiles.exe的实用程序 - 这应该可以满足您的需求

Answer 3

尝试robocopy！您必须先将所有文件移动到一个删除文件夹，然后在批处理文件中删除该文件夹，如下所示：

md C:\Delete
robocopy YourFolderToDeleteFrom C:\delete /E /minage:7
rmdir C:\delete /S /Q

bat脚本删除超过7天的文件
