I'm using RSJ, and Kev said to attach the DVD-R by RSJCd Writer and it can be formated by opening the drive and right clicking on it to get the context message and clicking on the erase command which formats the disk. I found that I can write to a new DVD-R without formating it so it must be formated already. Erased the data and was able to write to it again. Have not tried copying CD's but don't expect any problems.

Yes, you can, provided the zip.exe is in a sub-directory. I backup my D: drive eCS 1.1 using infozip and there are several zip.exe files below the root. > I presume the answer is no.

The above statement was assuming you had booted from "another" installation of os/2 or booted from the eCS boot CD or even floppy disks.

Hi Alan, As any CD-R or DVD+-R are writeable, but not *re-writeable*, if you erase any data off them, all you are actually doing is removing the entries relating to them from the Table-Of-Contents and thus directory entries. When you then append more data to the CD-R/DVD+-R, the new data doesn't reuse the space previously used by the deleted data. Of course this wouldn't be obvious to anyone deleting a few relatively tiny files! For example, if you have a disk with a capacity of e.g. 4.7GB, with 3.5GB of data written to it, then delete 2GB of that data, you don't then have 3.2GB free, you still only have 1.2GB, as you can't physically overwrite on *write-once-only* media and exactly the same applies for RW media [until you re-format/blank RW media]!

If you set them up in multisession mode you can fill them "chunk by chunk" but you cannot re-use space that you have already written to on it. CD-RW, DVD+RW and DVD-RW Disks on the otherhand can be erased or "blanked" for re-use as if they were new (empty) disks. This is sometimes called formatting. You can also use one of these disks as if it were a very large floppy disk a write, update and delete individual files.

You can even put the output zip file on the same disk (as long as you have enough space).

Just think of the -RW devices like enormous floppy disks.
