Conditional IF EXIST Statement for multiple filenames in BATCH file - batch-file

Question

I'm working on the following batch script and I'm not sure how I can achieve the results I'm looking for. I searched here as well as online, but I didn't see anything that looked like what I'm looking for. Any help is appreciated.
I need to check if two files exist as well as if they don't. Currently I've got the code below working, however if one file exists or is missing it goes in a 3rd direction (I've updated the code to account for the 3rd direction so now it works fine, but I know there is much room for improvement!). I know it's not pretty, but it works and the pretty code doesn't.
Please note that there are other files in the same directory with the same extensions, so searching by extension will not work.
Working Code:
#echo off
echo checking file structure...
if exist "file1.exe" (
if exist "file2.zip" (
goto ok
)
)
if not exist "file1.exe" (
if not exist "file2.zip" (
goto download
)
)
if not exist "file1.exe" (
goto download
)
)
if not exist "file2.zip" (
goto download
)
)
:download
echo downloading missing files.
:ok
echo Install successful
What I would like to do:
(The following code isn't expected to work, it's my thoughts written out)
#echo off
set file1=setup.exe
set file2=package.zip
if exist $file1 && $file2 then goto ok
else if not exist $file1 || $file2 goto download
Example of why checking for the two files alone will not work
echo checking file structure...
if exist "setup.exe" if exist "package.zip" goto TEST1
if not exist "setup.exe" if not exist "package.zip" goto TEST2
ECHO [Error!] - 1 File is present, the other is missing!
PAUSE
:TEST1
ECHO [Success!] - Found both files, YAY!
PAUSE
:TEST2
ECHO [Error!] - No matching files found.
PAUSE

Answer 1

The parentheses are neccessary for the else clause.
#echo off
echo checking file structure...
if exist "file1.exe" (
if exist "file2.zip" (
goto :ok
) else goto :download
) else goto :download
:download
echo downloading missing files.
:ok
echo Install successful
But the else isn't required at all because the program flow falls through to the download label
#echo off
echo checking file structure...
if exist "file1.exe" if exist "file2.zip" goto :ok
:download
echo downloading missing files.
:ok
echo Install successful

Answer 2

Why perenthesize? Simply try.
#echo off
echo checking file structure...
if exist "file1.exe" if exist "file2.zip" echo Install successful
if not exist "file1.exe" echo downloading missing "file1.exe"
if not exist "file2.zip" echo downloading missing "file2.zip"
or in a loop:
#echo off
for %%i in ("file1.exe" "file2.zip") do if not exist "%%i" echo %%i Must be downloaded & goto :EOF
echo Successful Installation

Answer 3

:again
for %%a in ("file1.exe" "file2.zip") do if not exist "%%~a" call :download "%%~a" &goto again
And then write an internal procedure to download the missing file supplied as %1
Possibly you'd want to install a counter and report in the :download procedure if the download is being executed, and if so of which file - and count the number of iterations to stop the process if the download fails too often.
An advantage here is that there's no real limit to the number of filenames that can be included in the parentheses

Answer 4

Found the solution! Added some if exist parameters to account for empty folders.
for /D %%I in ("%~dp0*") do (
cd /D %%I
if exist *pm.wav (
if exist *.xml (
tar -cvzf %%~nxI.tar.gz *pm.wav *.xml
)
)
)
cd..

Download & execute
#echo off
echo checking file structure...
if exist "C:\Users\Himel\Desktop\5MB.zip" (
if exist "C:\Users\Himel\Desktop\5MB.zip" (
goto ok
)
)
if not exist "C:\Users\Himel\Desktop\5MB.zip" (
if not exist "C:\Users\Himel\Desktop\5MB.zip" (
goto download
)
)
if not exist "C:\Users\Himel\Desktop\5MB.zip" (
goto download
)
)
if not exist "C:\Users\Himel\Desktop\5MB.zip" (
goto download
)
)
:download
echo downloading missing files.
