Rename multiple files in consecutive order

Hi I have 22 folders, each containing data named 00001.gen to 01460.gen. I need to combin those in to a single folder and name the consecutively, meaning 00001.gen to 32120.gen. Any one out there who can help me?

What decides the order in which the 22 folders are concatenated?

The 22 folders represent data from 22 consecutive years.

Do the 22 folders have a common base folder? If so:

SrcFolder  = 'C:\Your\Base\Folder\';  % Parent folder of the 22 folders
DestFolder = 'C:\Your\Destination\Folder\';
if ~isfolder(DestFolder)
   mkdir(DestFolder);
end

List = dir(fullfile(, '**', '*.gen');
for iFile = 1:numel(List)
   Src  = fullfile(List(iFile).folder, List(iFile).name);
   Dest = fullfile(DestFolder, sprintf('%05d.gen', iFile));
   copyfile(Src, Dest);
end

Yest they have a common base folder. I'll try your code. Thanks for your help.
