application : DIR_EXISTS_BOOL

Overview​

This video demonstrates the DIR_EXISTS_BOOL application command in Nitro-CELL, which checks whether a specified directory exists on the file system and returns a boolean result. This command is useful for validating folder paths before attempting file operations such as saving, exporting, or opening models from a particular location. By confirming a directory exists before proceeding, engineers can build more robust automation workflows that handle missing folders gracefully instead of failing mid-execution. The video shows how to enter the command with a directory path argument, execute it, and read the true/false result from the status column.

Key Steps​

  1. Enter the DIR_EXISTS_BOOL command with the target directory path
  2. Execute the command to check if the directory exists
  3. Read the boolean result from the output cell
  4. Use the result to conditionally proceed with file operations
  5. Combine with directory creation or error handling for robust workflows

Tips​

  • Use this check before Save As or Export commands that target specific directories
  • Combine with conditional logic to create directories that do not yet exist
  • The command checks the local file system accessible from the Creo session
