7zip: errors, problems, and questions

Question

i am trying to run a batch file that extracts only .jar files with 7z.exe
here is my code:

set location=%cd%
set filename=%location%\outputfolder
set unzip=%location\resources

cd %unzip%
7z e -o%filename% -ir!*.jar -y "%filename%\*.zip"

but it gives an exception: error: incorrect command line so i removed the -ir!*.jar and it then gives another error: error: cannot use absolute pathnames for this command so i changed the -o%filename% to -oC:\\outputfolder and it works!!!!!!(here is my script now):

set location=%cd%
set filename=%location%\outputfolder
set unzip=%location\resources

cd %unzip%
7z e -oC:\outputfolder -y "%filename%\*.zip"

but i need these features
how fix?

Answer 1

try it with double quotes, %cd% maybe has spaces:

7z e -o"%filename%" -i!*.jar -y "%filename%\*.zip"
