Use dir for files not in any folder

Hello every one,

I wanted to know if I can use dir commant for files that are not in any folder! ( In fact I want to know if I have to put the .mat files inside any folder and then use dir command)

Currently using dir command gives zero results for me.

data_list=dir('VectrinoData.228.22.Vectrino Profiler.00000/*.mat'); %This gives 0*1 struct

"..files that are not in any folder"

What is a file that is "not in any folder" ?

[Walter Roberson]

dir() can operate on the current directory; for example dir('*.mat')

You can also do things like dir('VectrinoData.228.22.Vectrino Profiler.*.mat')

a data file like the one attached.

Okay, what about it?

dinfo = dir('VectrinoData.228.22.Vectrino Profiler.00000.mat')

and then you would be able to examine dinfo.name, dinfo.isfolder, and so on.

The problem is that when I use dir('VectrinoData.228.22.Vectrino Profiler.00000.mat') it gives:

1*0 struct

empty result

Then as far as MATLAB can tell, that file does not exist in the current directory.

What shows up if you use

dinfo = dir('V*.mat')
{dinfo.name}.'

[mehra]

ın fact the exact file exists and matlab does not give any error, just the output is zero!

But I used your command and it worked

Thanks

What exactly showed up for the output of the above two commands?

@mehra : Check this again. I'm convinced that you have over seen something:

file = 'VectrinoData.228.22.Vectrino Profiler.00000.mat'
isfile(file)
folder = cd
list = dir(fullfile(folder, '*.mat'))
{list.name}

What output do you get?

[mehra]

This actually worked. But did not know how to accept the answer

dinfo = dir('V*.mat')

And by reducing the numbers of 0 (zeros) in the nam eof the file it also worked. so I guess there was something related with the name of the file.
