The important thing to look at is that this has not much to do with how many the files or folders are.
Start out with going through the motions step by step with one file. Then create a test case with a habdful of files and once that is done then you apply the solution on all of them and if the test case is done properly obly difference will be that it takes a bit longer. The difficult part is figuring out what tools to use to combine operations during unzip and there are several ways. One is using the task utils and a decision where to place the unzipped file is important. Working with handful of files and doing things manually in the beginning and not thinking about all the thousands until the test case is ready is very important. 2011/11/4 Skip Cave <s...@caveconsulting.com> > I have several thousand files which are distributed into about a thousand > folders.
