How can I list file-paths from different subfolders?

Hi,

I am looking for an option to create a list of paths of files which are stored in different subfolders. I have a big amount of data, which is stored in this way:

C:/directory01/person01/subdirectory01/file01.x
                       /subdirectory02/file01.x
                       /subdirectory03/file01.x
C:/directory01/person02/subdirectory01/file01.x
                       /subdirectory02/file01.x
                       /subdirectory03/file01.x
and so on...

I want so create different lists of paths which contain e.g. only 'the file01.x's' from 'subdirectory02' from each person.

So something like

C:/directory01/person*/subdirectory02/file01.x

Is this possible? I only find ways to choose every file01.x which exist in directory01 and have to delete afterwards by hand the files from 'subdirectory01' and '~03'

Thank you so much for your help!

Best Eliska

You can use

f=dir('C:/directory01/person*/subdirectory02/file01.x')

And to get the the cell array of absolute paths to these files:

FileNames = fullfile({f.folder}, {f.name});

If you need to access many files for processing, and can't load them to memory, try datastore.

Perfect, thanks! That was what I needed :)
