Auto Open ZIP File Contents After Download - windows

Question

I'm trying to write a batch file that will be executed by a filewatcher once a zip file is downloaded. After download the file is unzipped with the same name, then the zip file is deleted leaving only the file folder and a single PDF file inside. I just need the command to complete this action for the same file that is unzipped.
7z x -oC:\Users\"user"\Downloads\* C:\Users\"user"\Downloads\*.zip
del C:\Users\"user"\Downloads\*.zip
"command opening the file in the unzipped folder"
exit

Answer 1

#echo off
setlocal
:: Start in this dir.
cd /d "%userprofile%\Downloads" || exit /b 1
:: Dir where 7z extracts to.
set "extractdir=unzip_tmp"
:: Zips move here if files or folders exist in cd.
set "faildir=unzip_fail"
rem Continue only if zip files exist.
if not exist *.zip (
echo No zip files
exit /b 0
)
for %%A in (*.zip) do (
set "fail="
rem Unzip with 7z.
echo Unzip: "%%~nxA"
7z x -o"%extractdir%" "%%~nxA" >nul
if not errorlevel 1 (
pushd "%extractdir%" && (
rem Check if files or folders exist in parent dir.
for /f "delims=" %%B in ('dir /b') do (
if exist "..\%%~B" (
echo Exist: "..\%%~B"
set "fail=defined"
)
)
rem Open PDF file.
for /r %%B in (*.pdf) do (
echo Open: "%%~nxB"
start "" /wait "%%~fB"
)
rem Move files or folders to parent dir.
if not defined fail for /f "delims=" %%B in ('dir /b') do (
echo Move: "%%~B"
move "%%~B" .. >nul
)
popd
)
rem Cleanup.
if defined fail (
if not exist "%faildir%" (
echo Create: "%faildir%"
md "%faildir%"
)
echo Remove: "%extractdir%"
rd "%extractdir%" /s /q
echo Move: "%%~nxA"
move "%%~nxA" "%faildir%" >nul
) else (
echo Remove: "%%~nxA"
del "%%~nxA" >nul
)
)
)
rem Final cleanup.
if exist "%extractdir%" (
echo Remove: "%extractdir%"
rd "%extractdir%" /s /q
)
This uses a preset directory to extract the zip files to.
The variable named extractdir has the name of the folder to use.
A preset directory allows the ability to search for PDF files in
an isolated path.
The script is quite verbal so can see what is unzipped, moved etc.
Code operation:
Change directory to Downloads directory.
Exit if no zip files.
Search for zip file.
Extract from zip file to %extractdir%.
Check if extracted files and folders exist in parent directory.
If so, set fail to defined.
Search recursively for PDF files and open them.
if fail is not defined, move files and folders to parent directory.
Cleanup by deleting zip file or removing %extractdir%
and moving the zip file to %faildir% if fail is defined.
Finally remove %extractdir% if exist so it cannot foul up next run.

Use FOR, if you have multiple zip files, it will iterate over them all.
#echo off
for %%I in ("%UserProfile%\Downloads\*.zip") do (
"%ProgramFiles%\7-Zip\7z.exe" e -aoa "-o%%~dpI" -y -- "%%I"
if not errorlevel 1 (
del "%%I"
if exist "%%~dpnI.pdf" start "" "%%~dpnI.pdf"
)
)
This script says, here is the download path. For each PDF in this path, unzip and then delete the zip, open any PDF that was unzipped.

Answer 3

For those that want to try a fast one liner without dependencies this will depend on the file monitor calling the cmd line (as many can do)
you can add a command to go to a working download directory as required then for example if this page was in the zip as PDF run
forfiles /m *.zip /C "cmd /c md #fname && move #fname.zip #fname && cd /d #fname && tar -mxf #fname.zip && start \"\" #fname.pdf"
To delete the zip add && del #fname.zip onto the end of above before the last "
There should be little need for error checks as its conditional && so should not overwrite, the first abort should be
A subdirectory or file blah blah already exists.
