I went for a matching pair of one-liners, which worked very nicely:
if there is not a folder "this_folder" then create folder "this_folder"
if there is not a folder "this_folder/that_subfolder" then create folder
"this_folder/that_subfolder"
Just a reminder - don't forget to check "the result" after you do your
"create folder"; if the OS can't create it for some reason, you'll get
something back in "the result". Here's an example:
create folder "this_folder"
put the result into tResult
if tResult is not empty then
answer "Could not create folder. Error reported was:" && tResult
exit to top
end if
I find that "the result" string is often vague, usually reporting only
that it can't create the folder but not why.
In recent years I've taken to appending "the result" with the value
return from sysError for a more specific OS error code:
answer "Could not create folder. Error reported was:" && tResult \
&"("& sysError() &")"
SysError returns the OS code, which often will tell you the difference
between an invalid path, or a folder that already exists, etc.
