windows - Batch file ignores ELSE statement inside a FOR loop -

i creating batch file decompresses archives detect in specified folder. right trying detect archive files within specified folder using code:

@echo off setlocal setlocal enabledelayedexpansion  set quote=" set cwdtext=current working directory:  set cwd=%cd% set fullcwd=%cwdtext%%cwd% set path=%~dp0 set types=file_types.txt set fullpath=%path%%types%  echo %fullcwd% echo %fullpath%  :specifypath echo: set /p directory=specify full path location of archive files:  if "%cd%"=="%directory%" ( echo specified location current directory  goto specifypath ) else ( pushd %directory% cd goto checkarchives )  :checkarchives %%t in (*.zip,*.rar,*.7z) ( if exist %%t (     echo archive files detected     goto eof ) else (     echo archive files not detected     goto eof ) goto eof )  :extract echo extracting archive files  :eof pause 

the part wherein start checking archive files @ :checkarchives label. problem i'm having right whenever try specify folder wherein there no archive files, code jumps :extract label , not go else statement inside for statement. can explain why so?

i tried using if not exist... statement after first if statement still same behavior.

when element being enumerated for command doesn't contain wildcard, code in do clause executed , for replaceable parameter contain element is.

but when element being enumerated contains wildcard assumed needs expanded , file system checked presence of files matching wildcard expression. if there not files matching, code in do clause not executed element. if there files matching expression, code in do clause executed not expression, each matching file, , for replaceable parameter hold reference current one.

as code using wildcards if there matching files, code in do clause executed each of files (in case first file found because goto), and, if there not matching file, code in do clause not executed else clause can not reached.

but, lets suppose for not check file system, , elements indicated iterated written. have logic error. inner if command check existence of files matching first set. if not files matching first set found, leaving for command goto inside else clause, so, rest of sets not checked.

to keep for check existence of files better way be

for %%t in (*.zip, *.rar, *.7z) goto :extract echo no archives found goto eof 

if file, matching of wildcard expressions, found goto cancel current enumeration , jump :extract label. if for loop ends , next line reached because no matching file has been found.
