File Exists Node
The File Exists node checks if a file or directory exists in the flow directory.
Description
The File Exists node checks whether a file or directory exists at the specified path in the flow directory. The result is a boolean that can be used for conditional logic.
Execution Inputs
- In (execution): The execution flow enters through this pin
Variable Inputs
- Path (string): Relative path to check from the flow directory
Execution Outputs
- Out (execution): Execution continues after the check is performed
Variable Outputs
- Exists (boolean):
trueif the file/directory exists,falseotherwise
Special Notes
- Paths are relative to the flow directory
- Returns
falsefor invalid paths (outside flow directory) - Works for both files and directories
- Use this before attempting to read files to avoid errors
Example Usage
Check if a configuration file exists before loading it, or verify that required data files are present. Connect the Exists output to a Branch node's Condition input for conditional execution.
