If ... if ... Capture::Tiny. If ... then Win32::ShellQuote ...

Just unnecessary! (Ie. A waste of time and effort.)

If the shell (cmd.exe) requires quotes ...:

C:\test>"c:\Program Files\Direct Modeling Express 4.0\binx64\7za.exe" 
+a -y c:\junk.rar "c:\Program Files\Hitman Pro 3.5\*"

Creating archive c:\junk.rar

Compressing  HitmanPro35_x64.exe

Everything is Ok

Then invoking the same command via the shell, via backticks also requires, (and will work with) quotes ... (but use / instead of \ for paths!)

And that's *all* that is required. No ifs; no buts; learn the rules, and it just works.
