How do I extract all .zip in subfolders?

From a command prompt, you can use a command similar to the following to recurse through all files in a folder. I'm using *.zip, but you can use any filter you want there.

FOR /R %i IN (*.zip) DO "command"

This will recurse through the folder, and pass the matching filenames in as "%i". To see how it works, you can use the @echo command to print out the filenames that match. ("%~dpi" would be just the folder name)

FOR /R %i IN (*.zip) DO @echo Filename is "%i", folder is "%~dpi"

So if you were using 7-Zip, you could use a command like:

FOR /R %i IN (*.zip) DO "c:\program files\7-zip\7z.exe" x "%i" -o"%~dpi"

One way is with a batch file. The three main zip type file programs, WinRAR, WinZip and 7-Zip all have CLI (command line interface) parts.

One method to find all the zip files within your main directory is to write a dir command to get them into a file then work your way through the file working on each entry...

mkdir c:\zipped

dir drive:\path\*.zip /b /s > c:\zipped\files.txt

for /F "tokens=*" %%a in (c:\zipped\files.txt) DO (

....

)

Another method doesn't require the dir command

mkdir c:\zipped

for /r drive:\path %f in (*.zip) do echo %f >> c:\zipped\files.txt

for /F "tokens=*" %%a in (c:\zipped\files.txt) DO (

....

)

For /r - Walks the directory tree rooted at [drive:]path, executing the FOR statement in each directory of the tree. If no directory specification is specified after /r then the current directory is assumed. If set is just a single period (.) character then it will just enumerate the directory tree - http://www.computerhope.com/forhlp.htm

%f - a variable

* - ALL wildcard

echo - write the result (usually to the screen, but this is changed using >> or >)

>> redirect, append ( > simply overwrites the file)

files.txt - the file name, can be anything you like

You may even be able to do away with the text file list as well, but I haven't tried that.

for /r drive:\path %f in (*.zip) DO (

....

)

Where .... is the command lines from whichever zip file utility you use. You'll have to read about the various zip CLIs.

To write a batch file simply write the code in Notepad and save the file with a .bat extenstion. Simply double clicking on the file will run it.

Hi,

To open compressed files (zip rar jar iso 7z cab uue gz....) you have to use WinRar. With WinRar you can easily decompress files and folders.

You can find a recent release of Winrar here: http://bit.ly/1p3PcKC
