Thank you from the bottom of my heart for this useful tool. I compiled a fixed layout ebook with about 200 pages of photos and the file size with the source attached was over 80MB. KDP doesn't allow one to upload files bigger than 50MB, but the thing is my file is only 33 MB without the source files attached by KindleGen 2.7. So if your file plus the source is bigger than 50MB there is no way you can use KDP to remove the source attachment. Thanks to KindleStrip I removed the attachment and uploaded the 33MB file without any problems. The resulting fixed layout ebook works great both in the "Online Previewer" and in Kindle Previewer.
