删除文件小于特定大小 [英] Delete files less than a specific size

问题描述

我想删除小于目录中的特定大小的所有文件。有谁知道是否有一个Windows命令，将做到这一点？像德尔* *其中大小和LT; 3KB

I would like to delete all files that are less than a specific size in a directory. Does anyone know if there is a Windows command that will do this? something like del *.* where size<3kb

我目前这样做：

for /F %%A in ("*.pdf") do If %%~zA LSS 20103409 del %%~fA

和我得到的输出继电器是：

and the ouput I get is:

C:\Documents and Settings\agordon\Desktop\test>If 6440450 LSS 20103409 del C:\Do
cuments and Settings\agordon\Desktop\test\US Tox 01-06-11.pdf
The system cannot find the path specified.

...即使该PDF文件是小到足以被删除。

...even though that PDF file is small enough to be deleted.

我在做什么错了？

这是实际工作：

FOR %%F IN (*.pdf) DO (
IF %%~zF LSS 20103409  DEL %%F
)

然而，它不能识别的文件名，因为他们有空间！如何转换的Windows名称在脚本中的DOS叫什么名字？例如，Windows的名称为文件name.pdf 我可能会需要转换为DOS，它看起来像这样 file_name.pdf 或类似的东西。

However it is not recognizing the file names because they have spaces! How do I convert the Windows name to a "DOS" name in that script? For example, the Windows name is file name.pdf I would probably need to convert to "DOS" and it would look like this file_name.pdf or something like that.

推荐答案

从批处理脚本试试这个：

Try this from a batch script:

@echo off
setlocal
for /f  "usebackq delims=;" %%A in (`dir /b *.pdf`) do If %%~zA LSS 3145728 del "%%A"
