Using Windows OS fully

Passing Values with spaces

Utilize both " and ' signs.

!bld = %shell% "%_path%\.quail\cmd\build" "%_path%" '%vcvarsall_dir%' '%p1%'

Short path aliases

Windows automatically generates short path aliases that don’t contain spaces. For example:

Long path	Short path
C:\Program Files\filepath	C:\Progra~1\filepath
