I am trying to write a batch script that will run automatically compressing subdirectories using winrar or 7-zip:
Example:
My Pictures Pics1 (Pics1.zip) File1.jpg File2.jpg File3.jpg Pics2 (Pics2.zip) File4.jpg File5.jpg Pics3 (Pics3.zip) File6.jpg File7.jpg ... How do i write script.
(1) Using WinRAR:
WinRAR includes two command-line tools, rar.exe and unrar.exe, where rar.exe compresses and unrar.exe uncompresses files.
Both are located in the C:\Program Files\WinRAR folder in the installable version.
Assuming, if there are multiple subfolders under C:\MyPictures and you want each subfolder to get its own .rar file , in the parent folder.
From a batch file, this works for you:
@echo off setlocal set zip="C:\Program Files\WinRAR\rar.exe" a -r -u -df dir C:\MyPictures /ad /s /b > C:\MyPictures\folders.txt for /f %%f in (C:\MyPictures\folders.txt) do if not exist C:\MyPictures\%%~nf.rar %zip% C:\MyPictures \%%~nf.rar %%f endlocal exit Explanation....
It'll create .rar files of all the folders/subfolders under parent folder C:\MyPictures in the same parent folder.
Then, it'll delete all the original folders/subfolders under parent folder C:\MyPictures and thus you'll be left only with the archives at the same place.
“a” command adds to the archive
“-r” switch recurses subfolders
“-u” switch. Equivalent to the “u” command when combined with the “a” command. Adds new files and updates older versions of the files already in the archive
“-df” switch deletes files after they are moved to the archive
If you want to keep the original subfolders, just remove the -df switch.
(2) Using 7-Zip:
7-Zip is a file archiver with a high compression ratio.7z.exe is the command line version of 7-Zip. 7-Zip doesn't uses the system wildcard parser and it doesn't follow the archaic rule by which . means any file. 7-Zip treats . as matching the name of any file that has an extension. To process all files, you must use a * wildcard.
Using 7zip command-line options in a batch file, below works for you:
@echo off setlocal for /d %%x in (C:\MyPictures\*.*) do "C:\Program Files\7-Zip\7z.exe" a -tzip "%%x.zip" "%%x\" endlocal exit Where
-a archive or add
-t Type of archive
Here's how to do it in 7-zip.
Let's assume your files are in folder C:\Pictures\. Then you can use the following batch command to create multiple archives with the same name as your directories.
FOR /D %%i IN (c:\Pictures\*.*) DO "c:\Program Files\7-Zip\7z.exe" a "%%i.zip" "%%i\"
This will compress each folder in the directory Pictures. Change c:\Pictures to the directory containing your folders. If 7-zip is installed to a different directory, change the "c:\Program Files\7-Zip\7z.exe" to a directory where 7-zip is installed.
Thank you for the great script, I just had 3 issues/changes - directory names with space in name were not working, I just wanted to backup level 1 subdirectories and I wanted to pack all the subdirectories in the current directory (it's great for quick backup of all subdirectories separately). Here is the modification if you need something similar:
set zip="C:\Program Files\WinRAR\rar.exe" a -r -u -df dir /b /o:n /ad > .\folders.txt for /F "tokens=*" %%A in (.\folders.txt) do if not exist ".\%%~nA.rar" %zip% ".\%%~nA.rar" "%%A" Another approach if you need to recursively zip files in all subdirs in windows is to use gitbash and the approach described here:
find * -type d ! -empty -execdir sh -c 'cd "$1" && 7z a "$1".7z -x!*/ && cd -' sh {} \;This will:
You can also exclude specific types with:
find * -type d -execdir sh -c 'cd "$1" && 7z a "$1".7z -x!*/ -x!*.7z -x!*.zip && cd -' sh {} \;
