仅当文件大小大于时，才使用文件列表批处理文件以从文件夹和子文件夹复制文件 [英] Batch file to copy files from folders&sub folders using a file list only if file size greater than

问题描述

我们的数据库中有仓库库存的图像. 我们将这些图像的文件名列表拉入.txt文件.

We have images of our warehouse stock within our database. We will pull a list of the file names for those images into a .txt file.

file-list.txt的内容例如:

The content of the file-list.txt will be for example:

060128412948.jpg
068912475982.jpg
etc.

每张库存有3张图像，其中2张是低分辨率图像，而1张是高分辨率图像.

We have 3 images for each stock 2 of them are low resolution and 1 of it is a high resolution image.

我需要脚本仅将每张股票的高分辨率图像从文件夹/子文件夹复制到母目录中.

I need the script to only copy the high resolution image for each stock from the folders/sub-folders into a mother directory.

这是我到目前为止所拥有的，但这仅从源目标文件夹中复制文件列表中列出的文件.

This is what I have so far but this only copies the files listed in the file-list from the source destination folder.

@echo off

set src_folder=C:\Users\jakub.parszewski\Desktop\TT\SalesOrders\NewOrder
set dst_folder=C:\Users\jakub.parszewski\Desktop\TT\Test
set file_list=C:\Users\jakub.parszewski\Desktop\TT\File-list.txt

set maxbytesize=300000

for /f "delims=" %%A in (%file_list% do set size=%%~zA

for /f "delims=" %%f in (%file_list%) do (
    if %size% GTR %maxbytesize% 
    xcopy "%src_folder%\%%f" "%dst_folder%\"
)

推荐答案

虽然您在考虑实现更健壮的方法的潜在更好方法，但下面是一个For循环示例，该示例使用了与您的原始意图类似的方法.

Whilst you think about potentially better ways of achieving a more robust method, here is a For loop example using a method similar to your original intent.

@Echo Off

Set "src_folder=%UserProfile%\Desktop\TT\SalesOrders\NewOrder"
Set "dst_folder=%UserProfile%\Desktop\TT\Test"
Set "file_list=%UserProfile%\Desktop\TT\File-list.txt"
Set "maxbytesize=3000"

For /F "UseBackQ Delims=" %%A In ("%file_list%") Do For /F %%B In (
    'Where/T /F "%src_folder%":"%%~nxA" 2^>Nul'
) Do If %%B Gtr %maxbytesize% Copy "%src_folder%\%%~nxA" "%dst_folder%">Nul

Pause

我使用Copy是因为您的XCopy示例没有使用基本副本以外的任何选项.

I used Copy as your XCopy example didn't use any options beyond a basic copy.
