Batch脚本开发需求：按文件名批量归类家庭视频至指定目录

Hey there! Great job getting the single-file handling working already—first time coding and you’re off to a solid start. Let’s expand that script to automatically loop through all your MP4 files and organize them into Robofolder’s directory structure.

Here’s a complete batch script that does exactly what you need, with comments explaining each step so you can follow along:

@echo off
setlocal enabledelayedexpansion

:: Update these paths to match your setup
set "source_dir=C:\Your\Family\Videos\Raw"  :: Folder with all your unorganized MP4s
set "target_root=C:\Your\Family\Videos\Organized"  :: Where you want the sorted folders to go

:: Loop through every MP4 file in the source directory
for %%f in ("%source_dir%\*.mp4") do (
    :: Grab the filename without extension (e.g., "20150504_144132" from "20150504_144132.mp4")
    set "filename=%%~nf"
    
    :: Extract date/time components from the filename
    set "year=!filename:~0,4!"       :: First 4 characters = year (2015)
    set "month=!filename:~4,2!"      :: Next 2 = month (05)
    set "day=!filename:~6,2!"        :: Next 2 = day (04)
    set "hourmin=!filename:~9,4!"    :: Characters after underscore = hour + minute (1441)
    
    :: Build the Robofolder-style directory name
    set "target_dir=!year!---!month!---!day!---!hourmin!"
    
    :: Create the target directory (if it doesn't exist already)
    mkdir "%target_root%\!target_dir!" 2>nul
    
    :: Move the file to its new home (use "copy" instead of "move" if you want to keep the original)
    echo Processing "%%~nxf"...
    move "%%f" "%target_root%\!target_dir!\"
)

echo Done! All MP4 files have been organized.
pause
endlocal

Key things to know: #

• Delayed Expansion: The setlocal enabledelayedexpansion line is critical here. When you modify variables inside a for loop, batch needs this to recognize the updated values immediately (otherwise it would use the original value for every iteration).
• Path Customization: Make sure to change source_dir to the folder with your unorganized videos, and target_root to where you want the sorted folders to live.
• Safety First: If you’re worried about accidentally moving files you don’t want to, replace move with copy to test the script first—you can switch back once you’re sure it works.
• Error Suppression: The 2>nul after mkdir hides the "directory already exists" error message, so the script won’t spam you with unnecessary warnings.

Just save this as OrganizeVideos.bat, update the paths, and double-click it to run. It’ll handle all your MP4s automatically!
