I have a folder of 12000 images (in bmp format). I would like to randomly extract 2000 images and store it in a different folder. How can i do that?

Based on Adam's suggestions:
Dest = 'C:\Temp';
FileList = dir(fullfile(Folder, '*.bmp'));
Index = randperm(numel(FileList), 2000);
for k = 1:2000
Source = fullfile(Folder, FileList(index(k)).name);
copyfile(Source, Dest);
end
Or movefile.

doc dir
can be used to give you a listing.
doc randperm
can be applied to your listing to select the random files. I don't have time (or inclination) to write the code for you though so feel free to ask further questions once you have made an attempt if you get stuck.

You can do a dir in that folder for a list of files. Use a random number generator of 2000 length.
Select the file based on the random number.
