How can I make Inno Setup ignore empty directories?

Question

My Inno Setup script includes a directory:

[Files]
...
Source: C:\MyProg\Tools\*.*; Destdir: {app}\Tools
...

But sometimes this directory is empty and in that case Inno Setup stops with an error "No files matching ...".

My current workaround is adding an empty dummy file to that directory.

Can I make Inno Setup ignore this directory if it is empty?

Did you try the skipifsourcedoesntexist flag?

Source: C:\MyProg\Tools\*.*; Destdir: {app}\Tools; Flags: skipifsourcedoesntexist
