Extract all zip files in a specific folder

What zip software are you using?

Use 7zip. Perfect for the job !!

Get it from: http://www.7-zip.org/

you can use winzip at the commandline. so a batch solution is possible

@echo off
for /f "delims=" %%i in ('dir /b *.zip') do winzip -e "%%i" "%%~nI" -sPaSsWoRd

Select allOpen in new window

if each file has a different password you would need to call a second batch in the for loop (or a console program you provide) which is able to add the password to each file passed.

Are the passwords all the same, or unique to each file?  If all the same then it's doable, if different then it seems like you'd have to do single file sensitive processing so you knew which password to use.

They are the same ...

Is the target location for the extracted files the same for all zips, if so then you should be able to just use a wildcard filter on the zip command line, like:

7z x *.zip -psecret -oc:\temp

the batch file i posted would create a folder of same name as the zip file.

if you don't like the password to be stored in a batchfile you could pass it as argument instead.

then the for statement would change to

for /f "delims=" %%i in ('dir /b *.zip') do winzip -e "%%i" "%%~nI" -s%1

Select allOpen in new window

Sara & Billprew,

Yes I would like the data extracted from all into one specfic folder.

Okay, 7z with wildcards would work as I mentioned above then.

I own winzip...

i checked winzip on my notebook and found out that it is winzip32 and not only winzip.

try to start winzip32 from command line. type

winzip32 /?

and if that works also the for statement should work.

if you get an error you need to use the full path to winzp32.

assuming it is installed at c drive then do

c:
cd \
dir /s winzip*.exe

that should give you the path to winzip32.exe.

For winzip you actually want to get the command line addon (free to licensed owners) and use that from BAT files.

my winzip32.exe works from commandline. i didn't install an add-on for that.


Sara

I already know the full path to winzip command line:

"C:\Program Files\WinZip\wzunzip.exe"

Then it should be as simple as:

"C:\Program Files\WinZip\wzunzip.exe" c:\fromdir\*.zip c:\destdir

Billprew where should I add the password part since these zip files have passwords in them.

Also, fyi, if you do WZUNZIP at a command line with noting else it will open the help file where the various command line options are discussed.
