How can I compress multiple depth subfolders?

Retro Jack · 06 Jan 2022

Can anyone help me with a batch file to compress multiple depth subdirectories?

I would like to be able to turn

Code:

+---Pix
|   |   a.jpg
|   |   b.jpg
|   |   c.jpg
|   |   
|   \---Docs
|       |   a.doc
|       |   b.doc
|       |   c.doc
|       |   
|       \---Bills
|               a.xls
|               b.xls
|               c.xls
|               
\---Wishlist
    |   x.jpg
    |   y.jpg
    |   z.jpg
    |   
    \---Adverts
        |   x.doc
        |   y.doc
        |   z.doc
        |   
        \---Income
                x.xls
                y.xls
                z.xls

into

Code:

+---Pix
|   |   Pix.7z
|   |   
|   \---Docs
|       |   Docs.7z
|       |   
|       \---Bills
|               Bills.7z
|               
\---Wishlist
    |   Wishlist.7z
    |   
    \---Adverts
        |   Adverts.7z
        |   
        \---Income
                Income.7z

Notes:

My archiver (7z.exe) is already set in my path environment variable, so the batch file doesn't need to know where it is.
The contents of Pix.7z (for example) should only include the files in the Pix folder, not the contents of Docs or Bills.

Any help would be greatly appreciated.

Hi, it looks as if this has been addressed here:

But you may need to be prepared to test whatever you decide to try carefully- and when you do try this, use a copy of your original files just to be even safer. (I.e. always keep a backup).

I've just tried that, but unfortunately, that just zips each top-level folder and its contents into its own file; what I'm after would put each subfolder into their own zip files within the tree.

Thanks anyway.

I understand what you're looking for - there are variants on the idea in the comments following. I can't be sure if any of them, from the limited description, achieve exactly that, so I'd have to leave that to you. E.g. versions around this comment

7-zip has an option to UNZIP every file into its own folder (*/), but lacks the context commands to do the opposite action you are looking for.
That said, I remember doing this exact thing using winrar in the past. There's an option "unique archive per folder" or something to that effect.

There are other similar discussions e.g.
how to zip all files individually in all subfolders and remove original file after - Stack Overflow

The difficulty with any of these is how robust they are.. how they handle exceptions, and how reliable they are.

So would I be right in the assumption that you want to preserve the folders and only zip their contents into a 7z file with the same name as its folder?

Would this be as expected:

Assuming 7z.exe path is already in the %path% variable....

Code:

@echo off

:: Please drag and drop the main folder to this batch file

IF /i exist "%~1" (IF /i not exist "%~1\" exit) else (exit)
pushd "%~1"

for /f "Delims=" %%a in ('dir /b /s /ad') do (
                                              cd /d "%%a"
                                              7z.exe a -sdel "%%~na.7z" *.*
                                             )
popd

                                             )
popd

Thank you! That is exactly what I was after!

Muito apreciado!
