how to access a particular format files from a drive location?

hi.. In my D drive,many folders(app. 50 folders) are there.each having many formats of files.i need to access .zip files alone in each of the folders and move to separate folder..i am stuck here..

The following will return a struct containing the .zip files in the folder specified by path_to_zip_files:

my_zips = dir('path_to_zip_files\*.zip')

Then,

for k=1:numel(my_zips)
  my_zips(k).name
end

returns the names of the .zip files recursively. Adapt the code to your needs.

this code showing only .zip files in Desktop alone.but many .zip files are there in locations( \test),(\Users) ...i need to access all .zip files in C DRIVE fully,not in particular path,

   my_zips = dir('C:\Users\test\Desktop\*.zip');
for k=1:numel(my_zips)
  my_zips(k).name
end

try the function given in the following link for recursive search:

http://www.mathworks.com/matlabcentral/fileexchange/40016-recursive-directory-searching-for-multiple-file-specs

[David Sanchez]

the dir2 function provided there present a error, at least in my case. If you comment the " if ispc " condition, the recursive search works with no problem. With that part uncommented, an error message showed up regarding the mex file provided alongside the dir2.m file.

To find all your .zip files:

my_zips = dir2('your_folder','*.zip', '-r');

i think now you have all you needed

thanks...as i am using MATLAB 7.11.0(R2011b) version....dir2 function is not present in this version..any other alternate way to solve this??

[Cedric]

You have to download DIR2 from the URL given in David's answer, and extract/save it somewhere in your path or in the same folder as the script that you are trying to build/run.

thanks....now its SHOWING ERROR like this..any thing need to do with the MEX file?

16 errors, 24 warnings 

C:\PROGRA~1\MATLAB\R2010B\BIN\MEX.PL: Error: Compile of 'dir2_mex.c' failed.

[Walter Roberson]

Which compiler are you using? What have you selected with

mex -setup

?

[sandy]

 my compiler is   Lcc-win32 C 2.4.1  (default)...which compiler is better for this?

[Walter Roberson]

Please show the complete log of the compilation.

   mex -setup
Please choose your compiler for building external interface (MEX) files:

Would you like mex to locate installed compilers [y]/n? y

Select a compiler: [1] Lcc-win32 C 2.4.1 in C:\PROGRA~1\MATLAB\R2010b\sys\lcc

[0] None

Compiler: 1

Please verify your choices:

Compiler: Lcc-win32 C 2.4.1 Location: C:\PROGRA~1\MATLAB\R2010b\sys\lcc

Are these correct [y]/n? y
