fileparts — Split a path into folder, base filename, and extension.
Split a path into folder, base filename, and extension.
Syntax
[folder, name, extension] = fileparts(filename)Inputs
| Name | Type | Required | Default | Description |
|---|---|---|---|---|
input | Any | Yes | — | Input argument. |
Returns
| Name | Type | Description |
|---|---|---|
folder | StringScalar | Folder component. |
name | StringScalar | Base filename component. |
extension | StringScalar | Extension component including the leading dot. |
Returned values from fileparts depend on how many outputs the caller requests.
How fileparts works
- Accepts MATLAB text inputs such as string scalars and character row vectors for path, name, or URL arguments where applicable.
- Runs on the host using the active RunMat filesystem, environment, or HTTP abstraction as appropriate.
- Reports MATLAB-style runtime errors for unsupported argument shapes or unavailable host capabilities.
Using fileparts with coding agents
Open a RunMat example with live inputs, then ask the agent to explain how fileparts changes the result.
Run a small fileparts example, explain the result, then change one input and compare the output.
