We have several folders containing 3000+ files each. They contain scanned pdfs. Some of our staff have been scanning in blank pages to get around the system, and I have just finished going through them all by thumbnailing them via CFPDF and marking the offending files. I have all the filenames (good and bad) in a table.
I now need to keep up this task, looking at all new files added to the folders each week. I thought of the dateLastModified of CFDirectory, but some of the files will have old dates on them. Is there a quicker/better way (instead of going through a CFDirectory listing and querying the table for each file to see if it has already been processed)?
