Merging two PDF files from different folders

Lets say I have 100 PDFs in one folder1 (filename: 1, 2,3,4..) and another 100 PDF in another folder2 (Filename: 1,2,3,4...). Now I want to combine PDF1 in folder1 with PDF1 in folder2 and so on... till pdf100 from folder1 is combined with pdf100 in folder2.

The PDF in folder1 should be merged in the first page of the pdf1 in folder2. (this applies for all the pdf)

How can this be implemented? Can we use data merge? Will Photoshop be useful or indesign or acrobat reader?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

The Free version of PDFCreator provides a sample VBscript to merge files. Therefore, with some code changes, what you need can be done for free.

If you have Acrobat installed in the above packages, just use the Combine File function. I use this a lot.
