Matt Petrowsky, ISO Productions, Inc.

A custom function to create and open a folder on the Mac OS X operating system.

Sample Input:
f = folderName;
mypath = "/Volumes" & Substitute ( Get ( FilePath ) ; ["file:" ; ""]; [ Get ( FileName ) & ".fp7" ; ""] )

OpenFolder ( mypath; f )

Sample Output:
do shell script "path="/Volumes/Hard Drive/Users/me/Desktop/New Folder"; if [ ! -d "$path" ];then mkdir "$path"; open "$path"; else open "$path"; fi"

New folder (relative to the FMP file) is created and opened if it does not exist. Otherwise the folder is simply opened.

 Then copy & paste into FileMaker Advanced's Edit Custom Function window.



This function can be used to generate the AppleScript code needed to create and open a folder on Mac OS X. Simply supply a proper POSIX path and the name of the folder you want. It may not work with ~ designations so supply a full absolute path.

To use just make a script with Perform AppleScript and point to the calculation.

Note: these functions are not guaranteed or supported by Please contact the individual developer with any questions or problems.

This is my Custom Function and I want to edit it

How can this used in a script step?

This problem seems to remain still:

The following: "\"" in the function produces an error: List usage is not allowed in this calculation.

How can it be avoided?

Since Filemaker 7 :
Substitute ( cmd ; """ ; "\"" )
does not work.
You have to unescape everything, including the unescape character !
So you would write :
Substitute ( cmd ; "\"" ; "\\\"" )

That should do the trick here ;-)

My above comment is true, but won't work here. The function needs to b re-written.
The quoted forms are unnecessary, and you need single quotes on the path, rather than double ones. This should do the trickā€¦ at least it does for me ;-)

f = name;
mypath = path & name ;
pathVar = "$path" ;
sh = "if [ ! -d " & pathVar & " ];then mkdir " & pathVar & "; open " & pathVar & "; else open " & pathVar & "; fi";
cmd = "path='" & mypath & "'; " & sh; // RAW SHELL SCRIPT CODE
applescript = "do shell script \"" & cmd & "\"" // APPLESCRIPT FORMATTED PATH

Oooops !! I forgot to delete the
f = name;
line, which serves absolutely no purpose whatever.
You can delete without problem ;-)
