如何压缩文件夹中前缀相同的成对文件（含7z与文档文件）

Hey there! Let's get your paired files compressed together smoothly. Since you already have matching sets like File Name 1.7z and File Name 1 Directory.doc in your C:\destination folder, we can use a batch command to iterate through each pair and package them into a single compressed file.

Batch Command (Save as .bat file) #

Create a new text file, paste the code below, and save it with a .bat extension (e.g., pair_compress.bat):

@echo off
setlocal enabledelayedexpansion

:: Set your destination folder path here
set "dest=C:\destination"

:: Iterate through all .7z files in the destination folder
for /f "delims=" %%i in ('dir /b "%dest%\*.7z"') do (
    :: Extract the base name (without .7z extension)
    set "prefix=%%~ni"
    :: Define the corresponding .doc file path
    set "doc_file=%dest%\!prefix! Directory.doc"
    
    :: Check if the matching .doc file exists
    if exist "!doc_file!" (
        :: Compress both files into a new combined .7z
        "C:\Program Files\7-Zip\7z.exe" a "%dest%\!prefix!_combined.7z" "%dest%\%%i" "!doc_file!" -stl -mx=5 -mhe -mtc -bb
        
        :: Optional: Uncomment the lines below to delete original files after compression
        :: del "%dest%\%%i"
        :: del "!doc_file!"
    ) else (
        echo Warning: No matching .doc file found for %%i
    )
)

echo Done processing all file pairs!
pause

Key Details & Explanations #

• setlocal enabledelayedexpansion: Needed to handle variables with spaces and update them correctly inside the loop.
• dir /b "%dest%\*.7z": Lists all .7z files in the destination folder in bare format (only filenames, no extra metadata).
• %%~ni: Extracts the base name of the .7z file (e.g., File Name 1 from File Name 1.7z).
• 7-Zip Command: We reuse your original compression parameters (-stl, -mx=5, etc.) for consistency. The new compressed file will be named like File Name 1_combined.7z.
• Optional Cleanup: If you want to remove the original .7z and .doc files after creating the combined package, uncomment the del lines.

Quick Notes #

• Make sure the path to 7z.exe is correct (the example uses the default installation path; adjust if you installed 7-Zip elsewhere).
• If you want to run this directly in Command Prompt instead of a batch file, replace all %% with % in the command.
