i need a function that will take adirectory name and return a list of all mp3 files present in that directory and all it's sub directories?

i want to get the all (.mp3) file names along with full path in matlab. kindly help me.

Answer 1

[Image Analyst]

My attached demo will do that. Just change the file pattern to *.pm3

[Muhammad Naveed]

thanks a lot.i want to use the function in C# , written in matlab so ..?

[Image Analyst]

You can ask in a C# forum for C# code, or else compile the MATLAB code into a DLL.

[Muhammad Naveed]

Can we save these fullfileNames int a list. to rturn using function?????

[Image Analyst]

Yes. You can make a function that takes a top level folder and then returns a list of all mp3 files within that tree.

Muhammad - look in the File Exchange for a recursive directory listing submission. One such example is Thomas Vanaret's rdir. Using this file, from the current directory, you could try something like

 rdir([pwd '/*.mp3'])

or

 rdir([pwd '\*.mp3'])

depending upon your OS.

[Muhammad Naveed]

thanks for your attention sir.i want to return the file names with full path.

[Geoff Hayes]

The above function will return a structure with the full path to each file. For example, if I run then following command to find text files in my current directory (note that I am using a Mac)

 >> rdir([pwd '/*.txt'])

I see the above output. If I save this to a structure as

 myTxtFiles = rdir([pwd '/*.txt']);

then

 >> myTxtFiles(1).name

 ans =
/Users/geoff/matlab/testing2/KEmode2_G201.txt

and so I can get the full name and path to the text file.

[Muhammad Naveed]

thanks. is it for one directory ? how to go through with subfolders? kindly guide me.

[Geoff Hayes]

The above example is for one directory. For sub-directories you can try

 >> rdir([pwd '/**/*.txt'])

Note the differences between the above output and the previous example. You may have to experiment with the code to do what you want...
