I have downloaded some LROC CDR 500MB images but am unable to unzip them. WinZip gives an error message - I suspect the zip file is too big for it. Irfan says it can't read the headers. NASAview seems to unzip them but displays them as completely white images but for a few hints of craters that appear as very pale grey.
Could anyone suggest an unzip program? Ideally I would like to display the images in Photoshop. Terry. |

Ok, I'm doing one as an experiment, but it's downloading as an IMG file, not as zip. Maybe IMG files are associated with zip on your system so it looks like a zip file? As for not handling the full size, you can try just opening the first 30000 rows as an experiment, if you can't get the whole image (I've done that on an older machine) - enter the width, 5064 pixels, and the height, 30000. You'll get a message saying the size is smaller than the file but you just ignore it.
