Hi In the past when I've needed a file from an image, I've thrown together a file extraction program to get the file of the image. I usually also write something to put an file back to an image. Often the write back of a file is as simple as I can make it. I usually write to an formatted image with no other files. This makes allocation easy. For CP/M I've only copied files from archives and not images. I've then transferred the files serially to my IMSAI. If it is a binary, I convert to HEX and then use the debugger to write it to a file. For CP/M-8000, I've written code to extract from a 8 inch image and then write these files to 5-1/4 images for the Olivetti M20. In this case, I've always build a new image with complete files for that image and not added files to a disk with files on it. Again, this is the easiest way to handle these. I've seen a few utilities on the web to read and write files to images but I've never used or needed any of these. I an usually interested in learning that particular systems file format and find the best way to learn it is to write something to transfer files. Dwight
