Function source:

function FileExists ( string FilePath ) 
   FunctionID 229; 
   if ( isMac ) then
      FilePath = substitute ( FilePath, ":", "/");
      if ( ! file_exists ( FilePath ) ) then
         if ( left ( FilePath, 1 ) != "/") then
            FilePath = "/Volumes/" + FilePath; 
         else
            return false; 
         end if
      else 
         return true; 
      end if
   else
      FilePath = substitute ( FilePath, "/", "\\");
   end if
   return file_exists ( FilePath ) ; 
end

FileExists Similar to the DirectoryExists function, but addresses a file instead. Checks if a file exists at the specified path, with platform-specific adjustments for macOS and Windows.

Example

Set Variable [$res; ACFU_FileExists( string_FilePath)]

- macOS: Replaces colon (:) separators with forward slashes (/). If the file does not exist, the function checks if the path starts with /. If not, it prepends /Volumes/ to the path and checks again.

- Windows: Replaces forward slashes (/) with backslashes (\), the standard directory separator in Windows paths.

Note: On Windows, both forward slashes and backslashes are supported as directory separators by other file-related functions in the plugin.
