How can I show all files within all subdirectories of a specified directory in MATLAB?

Best Answer

You can generate all the directories of the current folder you are on by using the "system" command and the operating system's "dir" as input:

>> [status, cmdout] = system('dir /s /b');

The output of the command is in "cmdout".

To search for file that are not on MATLAB path, use the DIR command in MS-DOS. For this, use the CD command to the top level directory, and use the DIR command within the DOS command from MATLAB this way:

[a,b] = dos('dir /s /b <myfile>*');
filenames = textscan(b,'%s','delimiter',char(10));
filenames = filenames{1};

Here the /s option looks inside subfolder and <myfile> is the file that you are searching for. The /b option ensures that the output is in bare format.

MATLAB: How to use “system” command without MATLAB environment

You can override an environment variable in the "system" command.

For example, on a Windows platform, the following code sets the PATH variable to "myPath", then calls the "system" command "dosCommand" with that value.

>> system(['set PATH=' myPath ' && ' dosCommand])
