Change file extension from .wav to .res

Hi. My question might sound naive but can u please explain me in detail as to how to change the extension of a file from .wav to .res using MATLAB. P.S. all my files are stored in different names in the same folder

[Daniel Shub]

Do you want to change the extension or change the format? Renaming a file is very different from converting a file.

i want to change the extension.

Answer 1

[Walter Roberson]

The MATLAB command to rename files is movefile()

Answer 2

[Chaowei Chen]

Supposing you just want to rename the file, do this

! ren temp.wav temp.res

[Walter Roberson]

That is not portable between operating systems.

[Chaowei Chen]

Thanks for the note. I didn't aware that.

However, in Windows, ren is faster than movefile, which copies and deletes files and therefore may be time consuming. My experience. :)

[Walter Roberson]

Can Windows rename be used between different file systems? Can it be used if one of the filesystems is on a networked drive?

The unix-type utility corresponding to rename is "mv". It too is usually much faster than movefile() . The MATLAB definition of movefile() has some odd semantics about the file permissions that result that make the simple and fast "mv" not an exact equivalent. I have not yet been able to come up with a situation in which the movefile() permission semantics would be the desired ones, but I _guess_ there must have been a Good Reason somewhere along the way...

This is a C-Mex, which is about 20 times faster than MATLAB's movefile under Windows (I do not have a measurement under Linux):

Answer 3

[Daniel Shub]

For renaming you should be able to extrapolate from the second example at:

http://matlab.wikia.com/wiki/FAQ#How_can_I_process_a_sequence_of_files.3F

you can use either the MATLAB movefile command or use the ! to invoke a system command to use your OS built in move/copy/rename command.

This was thought as a comment to Walter's answer, but the "Save" button of the comments is currently not working - on my computer.
