Can't Delete from CD-RW

Roxio and Nero do this through what is called 'packet writing' (which means you can add files to a CD later, a bit like closing the seesion ans leaving the disk open for normal CD writing). And they to can't erase files of a disk, however, they write a mark that the file is deleted and don't show it anymore... It's not gone and can be recovered easily though.

Packet writing allows you to write to a CD (not only CDRW, also normal CDs) somewhat like a floppy. It's useful for little "on-the-fly" storage, but as Legolas wrote, deleted files are not really deleted, and you can't recover disk space occupied by them. So, the available space can be easily over.
It's not a hard problem, as CDs are very cheap, and on the other hand you can erase a CDRW for a new session.
But, take care: "formatting" a CD for a packet session require little time (a few seconds), while formatting so a CDRW may be a pain (depending on the driver speed, also HOURS!!).
More: if you don't leave a 20-25Mb of spare space, you can't "close" the session on a packet writing formatted CD, making the CD readable on all CD readers. It'll be readable only on the proprietary drive or... other CD writers... that's at least what SHOULD be: I found sometimes problems on CD not "closed", also in MY driver.
AND, if something goes wrong, the CD could be definitely GONE, also a CDRW! In other words, you may have an useless unerasable CDRW.
In conclusion: packet writing on CDs can be useful for little storage of data; I feel this should be more usable on DVD writing.

I have Nero Express 6 and I cannot erase a file nor can I place a single file into a folder. Nor can I do editing of the document yet I'm using RW CDs.

I have been trying to find out why I'm having these problems by retrieving the Manual on Nero's disk as well as there website but it's in PS 6 SE [V-Box] program that I cannot purchase from Broderbund. It's not available and was told to purchase their PS 21. This does not work for the Nero Manual.

Help! Thanks!

Right click on the drive containing the CD and select the option 'Erase CD RW' from list.

EDITOR'S NOTE: That should work to erase ALL the files on the disk. But I believe the original question was concerning how to erase a single file from a CDRW disk.

Thanks!!!!!!!!!! thankfully your answer opened on the first page on google, and i did the needful.

I was Burning a movie using DVD Flick and Img Burner,For some odd reason I got an error,So I've to stop the burning process,How can I delete/re-use the same disk again? I'm using DVD-R Disks.

EDITOR'S NOTE: Chances are the disk is ruined. DVD-R is write-once. With a DVD-RW you could probably do it.
