My website is somewhat bigger (75k products), quite slow (but that is a server issue at present)

what I really want to do is reload all my products and images fresh, as I am aware there are quite number of products that do not have the correct image filename being used (image missing in other words)

I have a desktop folder containing all the images, and I have my csv files ready to upload using easypopulate.

what I want to do is to compare the filename of the image filename within each csv file, with the actual images I have in my folder, and if the image in the folder does not exist, have each csv file image filename marked (or deleted), so I can delete the input line before my easypopulate upload.

Perhaps anyone with excel knowledge can assist, or anyone who could write me a script/bat file to automate the job?

any help gratefully received
