It can help you writing the code more readable and helps to read (i.e.
understand) the code by hints and find declaration.

An one liner with only one used variable is a pretty safe 'with' and
is mostly a matter of taste.

But a complicated expression like PathArray[High(PathArray)]^ can be
made more readable (easier to understand) like this:

LastPath:=PathArray[High(PathArray)];
fillchar(LastPath^.StatisticOfFiles,sizeof(LastPath^.StatisticOfFiles),0);

Use Ctrl+Shift+C on LastPath to create the pointer variable.
