isfolder

Determine if input is folder

Syntax

result = isfolder(folderName)

Description

result = isfolder(folderName) returns logical 1 (true) if folderName is a folder located on the specified path or in the current folder. Otherwise, isfolder returns logical 0 (false).

Examples

Is Input a Folder

Create the folder myfolder, then check if myfolder is a folder. A result of 1 indicates that myfolder is a folder.

mkdir myfolder;
result = isfolder('myfolder')

result = logical
   1

Check if the inputs myfile1.txt and myfolder are folders. A result of [0 1] indicates that myfile1.txt is not a folder and myfolder is a folder.

result = isfolder(["myfile1.txt", "myfolder"])

result = 1×2 logical array
   0   1

Input Arguments

folderName — Folder name

string array | character vector | cell array of character vector

Folder name, specified as a string array, character vector, or cell array of character vectors. For a local file, folderName can include a relative path, but the relative path must be in the current folder. Otherwise, folderName must include a full path. If the folder is at a remote location, then folderName must contain a full path specified as a uniform resource locator (URL). For more information, see Work with Remote Data.

Extended Capabilities

C/C++ Code Generation

Generate C and C++ code using MATLAB® Coder™.

Usage notes and limitations:

• Use of file: in the specified path is not supported.

• No preprocessing is applied on the specified path.

• In certain cases, the behavior of the generated code might differ from MATLAB^®. In such cases, the behavior of the generated C code matches that of stat on UNIX^® and GetFileAttributesA on Windows^®.

GPU Code Generation

Generate CUDA® code for NVIDIA® GPUs using GPU Coder™.

Refer to the usage notes and limitations in the C/C++ Code Generation section. The same usage notes and limitations apply to GPU code generation.

Thread-Based Environment

Run code in the background using MATLAB® backgroundPool or accelerate code with Parallel Computing Toolbox™ ThreadPool.

The isfolder function fully supports thread-based environments. For more information, see Run MATLAB Functions in Thread-Based Environment.
