hi guys, i have this scripts which extracts all my folder's and files from my c:\projects locations and put its in winrar and transfers them to c:\backup\project

for /f "delims==" %%D in ('DIR C:\projects /A /B /S') do (
"C:\Program Files\WinRAR\WinRAR.EXE" m -r "c:\backup\projects.rar" "%%D"
)

i have also tried the below script which uses the same source c:\projects

but put them in their own separate winrar folder like in the source then transfers the folders into my c:\backup.

FOR /F "DELIMS==" %%D in ('DIR C:\projects /AD /B') DO (
"C:\Program Files\WinRAR\WinRAR.EXE" m -r "C:\Backup\%%D.rar" "%%D"
)

my question is, my second scripts only takes two hours to run when my first script takes over 24 hours to run, is there any way to make my first script faster? if anything shouldn't my first script be faster?
