How can I directly convert >PC files to CELLQuest format, so I can cut single-session CD's? When I went to BD, I brought some of my CQ files. I had moved them onto a server, and FTP'ed them to my IBM desktop. When I took them to BD, sure enough, CQ couldn't see them. To make it short, a quick chat with one of their software engineers confirmed what you've said - that being the files have had their "resource stamps" changed from Apple/Mac to IBM. The very minute the CQ files were transferred over to an IBM formatted disk, this is changed. THE only way we were able to convert them back such that CQ could read them again was through (on a Mac, of course) Norton Disk Doctor within which we had to physically change all of 2 letters and resave the file. With the correct information, CQ was then able to read the file. The data isn't lost, just the "covering" or "outer folder" that contains the data. I don't recall what the letters are but it can be easily had by using NDD to open a CQ file and copying down the file header information. Then when a former CQ file is opened that had been on an IBM disk, the resource information will be slightly different. That is what needs to be changed and only that - change anything else in the file (read: dangerous) and the data will no longer be accessible. For me, that was more trouble than it was worth. So when I moved data to my IBM it means that the only thing I can use to reanalyze will be WinMDI and the transfer of data can only be *unidirectional*. >Also, I wanted to try Toast on this same drive on a Quad 650, but I've just >learned that the Mac doesn't read PC Zips faithfully. Some "folders" are >mistaken as System folders with zero files! Sorry, no experience with this one... we archive to a unix server which still retains the CQ resource information. It would be nice if BD could "dink" with it so that CQ could read CQ files no matter by what means they were archived... Hope this helps, David ============================= David L.
