I tried to use this to split up a large pdfs. The result is that it can’t work as it said. I think I wasted my money, I was looking for a pdf reader that could do all of things this program probably does quite well. In fact this is not a reader. You can not extract pages from a documents as you review it. I bought this hoping it would extract text zna all it did was save a blank text file. When I start to group different pdf, each pdfs starts loosing the pdf files that each pdf has. That’s a big trout, it makes all my pdfs files confusion. I have to put my files in order. So that I can find them easily. I am fighting with times everyday, itbmakes me waste a lot time. Now I have add other app to do the same work.
