Create a folder called newfolder in the folder testdata. Use a relative path, where newFolder is at the same level as the current folder.

mkdir ../testdata newFolder

Create Folder That Already Exists

Open Live Script

Create the same folder twice, verifying the status of the operation after each try.

Create the folder newFolder. The operation succeeds, returning a status of 1 with no error or warning message.

[status, msg, msgID] = mkdir('newFolder')
status = logical 1
msg = 0x0 empty char arraymsgID = 0x0 empty char array

Create the folder newFolder again. The operation succeeds again, returning a status of 1. A warning message and message ID inform you that the folder already exists.

[status, msg, msgID] = mkdir('newFolder')
status = logical 1
msg = 'Directory already exists.'
msgID = 'MATLAB:MKDIR:DirectoryExists'

Input Arguments

collapse all

folderNameFolder name
character vector | string scalar

Folder name, specified as a character vector or string scalar. You can specify folderName as an absolute or relative path, unless a parent folder is specified. If you specify a parent folder, then folderName must be a path relative to the parent folder.

If folderName contains a path that includes one or more nonexistent folders, MATLAB attempts to create the nonexistent folder. For example, for the path myFolder\folder1\folder2\targetFolder, if folder1 does not exist, MATLAB creates folder1, creates folder2 within folder1, and creates targetFolder within folder2.

Data Types: char | string

parentFolderParent folder
character vector | string scalar

Parent folder for the new folder, specified as a character vector or string scalar. Specify parentFolder as an absolute or relative path. If parentFolder does not exist, MATLAB attempts to create it.

Data Types: char | string

Output Arguments

status — Folder creation status
0 | 1

Data Types: logical

msg — Error message
character vector

Error message, returned as a character vector. If an error or warning occurs, msg contains the message text of the error or warning. Otherwise, msg is empty, ''.

msgID — Error message identifier
character vector

Error message identifier, returned as a character vector. If an error or warning occurs, msgID contains the message identifier of the error or warning. Otherwise, msgID is empty, ''.

Tips

  • You can use mkdir to create folders in remote locations. To write to a remote location, folderName or parentName must contain the full path of the file specified as a uniform resource locator (URL) of the form:

    schema_name://path_to_file/folderName

    or

    schema_name://path_to_file/parentName

    It is also valid to use one or three "slash" (/) characters between schema_name and path_to_file. For example:

    schema_name:/path_to_file/folderName

    or

    schema_name:///path_to_file/parentName

    Based on your remote location, schema_name can be one of the values in this table.

    File Systemschema_name
    Amazon S3™s3
    Windows Azure® Blob Storagewasb, wasbs
    HDFS™hdfs

    If the file system being used does not support empty folders then attempting to use mkdir with that service will throw an error. For more information, see Work with Remote Data.
