With the way you describe your situation, you need to copy the files on the existing/current CMS minidisk to a temporary area. That could be another minidisk of equal or larger size or TAPE DUMP the minidisk (if you have some kind of tape subsystem available). Once the COPY or TAPE DUMP is done. You can then redefine the existing area, making it larger and then COPY or TAPE LOAD the data back to the new area. You may want to keep the current create dates of the files on the minidisk. If that's the case, use the OLDDATE option parameter when using COPY. TAPE DUMP/TAPE LOAD will automatically keep the create date. Why don't you want gaps? They don't hurt anything and it just makes more work for you, trying to eliminate the gaps, when you want to move things around. BTW, you are talking about CMS files on a minidisk, correct? Not a minidisk defined for use by Linux or some other non-CMS minidisk. If so, the COPY or TAPE DUMP won't work for this situation. Steve

Hello, Question on expanding a CMS. Normally I create a new mini disk(larger) and use COPYFile <Old to New> mini disk. That could leave Cylinder gaps on disk when old mini disk is deleted. Is there a procedure that allows me to back up a mini disk and restore to a new larger mini disk, aside from using COPYFile? DDR seems to be a Cylinder to Cylinder backup/restore?
