Introduction

For this tutorial, you need to declare a table in your AIModel variables, I named it tTable.
create a function named getFile and add the variable sFileURL as parameter.

Get the path

Start the script by clearing the table data:
table.empty ( this.tTable ( ) )

Use now the string.explode. The delimiter will be the “/” character. Use the sFileURL variable plus “/” as first parameter, the table as second parameter, and “/” as delimiter (third parameter).
string.explode ( sFileURL..”/”, this.tTable ( ), “/” )

The last item of the table is the filename with its extension:

Get the filename and the extension

local sFilenameAndExtension = table.getLast ( this.tTable ( ) )

Logically, the path of the file is the URL without the file and the extension:
local sPath = string.getSubString ( sFileURL, 0, string.getLength ( sFileURL ) – string.getLength ( sFilenameAndExtension ) )

Now you have to separe the filename to its extension, you must find the “.” symbol:
local nDotIndex = string.findFirst ( sFilenameAndExtension, “.”, 0 )

The extension is the part at the right of the string:
local sExtension = string.getSubString ( sFilenameAndExtension, nDotIndex, string.getLength ( sFilenameAndExtension ) – nDotIndex )

And the filename is the other part:
local sFilename = string.getSubString ( sFilenameAndExtension, 0, string.getLength ( sFilenameAndExtension ) – string.getLength ( sExtension ) )

It is finished, you can return the results:
return sPath, sFilename, sExtension
