How to Delete Files from an External Drive?

[bildio]

I'm new to Mac.

I copied some directories/files from my PC to a LaCie external drive. I then copied them from the drive to the iMac.

I tried to delete, e.g., drag to Trash, them from the external drive while connected to the iMac. It didn't work. I tried a mouse right click, but no delete on Menu. Is there a way to delete files on the iMac? I ended up connecting the drive to the PC, & deleting the files, but I'd like to be able to do the same from the iMac.

The disk is probably formated NTFS. Apple can read NTFS, but not write to it without software such as ntfs-3g from a 3rd party.

I don't know if the external drive is formatted NTFS or FAT. How can I find the drive format?

Right click on the drive while it's mounted on your desktop and right click. It will open a window that looks similar to this

Where it says "Format: Mac OS Extended " it will tell you the format of the drive in question.
