Q&A for How to Use 7Zip to Create Multiple Compressed Folders in One Go

Create a bat file with the following command (replace pdf with desired extension): FOR %%i IN (*.pdf*) DO "c:\Program Files\7-Zip\7z.exe" a "%%~ni.zip" "%%i".

Spaces in the folder names did not cause any issues for me. Test it out on a few practice folders and you should be able to tell if there are any issues.

Yes; after the command, add the -p switch and then the password with no spaces between (i.e. "-ppassword"). Add -mhe on the end of that to encrypt the headers, which that means that whoever opens the zipped archive will have to provide a password to view its contents.

Edit the .bat file and put which ever one of these that you want at the end. -m0=LZMA2 sets the compression method to lzma2 . -mx=9 sets the compression level to ultra. -mfb=64 sets the word size to 64. -md=32m sets the dictionary size to 32 megabytes. -ms=on sets it to solid.
