I have a server that accumulates a number of files everyday. The file's names can vary wildly, and I've found that they include ! points.

I took a batch file I found online and modified it to work for my purposes. Now I'm running into a problem with how it is handling ! since I'm using the ENABLEDELAYEDEXPANSION setting.

It is setup so that it won't delete itself and another batch file.

Oh and when writing this post, I noticed the folder contains files with filenames that include chinese characters! LOL

When the batch file encounters a file with an exclaimation point, it throws a:
"Could Not Find C:\uploads\20100826154948 - same error.gif"

File's name 20100826154948 - same error!.gif

Code: Select all

@echo off

I believe that batch file has the same issue as the one I presented. I ran it in my test directory:

20100826154948 - same error.gif = 20100826154948 - same error!.gif

C:\test>fileages morethan 1000 Del c:\test
The system cannot find the path specified.
20100826154948 - same error.gif is 734694 days old
deleteme.txt is 1 days old
FileAges.bat is 0 days old
Filechecker.bat is 2 days old
RenameIt.bat is 3 days old
test.bat is 1 days old
test.ps1 is 1 days old

C:\test>fileages c:\test
20100826154948 - same error.gif is 734694 days old
deleteme.txt is 1 days old
FileAges.bat is 0 days old
Filechecker.bat is 2 days old
RenameIt.bat is 3 days old
test.bat is 1 days old
test.ps1 is 1 days old

Edit: I just noticed that the "same error" file isn't that old either. =)

You can also run into problems if the name contains ^. The solution is to transfer the FOR loop variable to a normal variable with delayed expansion disabled, and then do the remainder of the loop with delayed expansion enabled, making sure to endlocal before loop end. This is also a common technique when trying to process the contents of a file with a FOR loop.

Note: You can provide both SETLOCAL arguments to one command.

Try this (untested) - Note I did not bother reposting the functions at the bottom:

Code: Select all

@echo off
::------------------------------------------------------------------------------------
::-- This batch file is designed to delete any file within it's folder that is older
::-- than 1 day.  This file is intended to run within C:\Uploads folder.
::------------------------------------------------------------------------------------
setlocal EnableExtensions DisableDelayedExpansion

call:jdate tnow "%date%"

for %%F in (*.*) do (
  call:ftime tfile "%%F"
  set /a diff=tnow-tfile
  set "file=%%F"
  setlocal EnableDelayedExpansion
  if !diff! GTR 1 if "!file!" NEQ "RenameIt.bat" if "!file!" NEQ "Filechecker.bat" (del "!file!")
  endlocal
)

GOTO:EOF

Edit Note: Fixed the references to file in IF statement to use delayed expansion
