Thanks Force Flow and Alex for your responses.
I have had a look at OmniPage / PaperPort (both products of Nuance). They dont offer a trial version and looked at their video tour.
I am not sure why companies do not offer such an automation tool (bulk processing of multiple batches) All offer automation tools for single batches.
To explain in detail what I am looking at it this:
I have 10 files that I need to scan. Say each file has 5 pages.
So I create a new batch take one file, scan the 5 pages and save the batch. I do the same thing for all my 10 files.
Hence now I will have 10 Batches.
Now say I want to automate a task (if you know automation like in Photoshop Actions)
For the automation task say I want to
Open Batch from a folder - where I can select the folder having 10 Batches
Then When a batch is open do the following tasks
say in task I can say Save AS PDF with options
which would save the Batches as PDF Files. Say file1.pdf, file2.pdf.... file10.pdf
or say I want to create a task Save as TIFF which would like
create a folder file1 and under it save pages like file1_1.tiff, file1_2.tiff... file1_5.tiff
Such bulk automation tool I could not find any where...
It would be great if some one could let me know if such a tool is available.
