where X is the drive letter, from A to P. If you have created multiple files referring to the same drive letter, CP/M will use the ones named cpm-X in preference to the ones named drv-X. It has no preference over .p3d or .dsk, so if there is a cpm-b.p3d and a cpm-b.dsk, then the first one in the directory will be used.
Note that NextZXOS will also automatically mount these drive images (except any image where X is c) when it starts up. You can view them in the Browser (press D to change drives) and copy files between them etc. NextZXOS will mount drv-X files in preference to cpm-X files. You can also manually mount other disk images which don't follow the automatically-mounted naming scheme. To do this, just press ENTER on the .p3d or .dsk file in the Browser.

There is a lot to learn about CP/M, and a lot you can do with it. Some useful places for further information are listed below:
http://www.cpm.z80.de/ Contains a lot of manuals, documentation and software.
In particular, the CP/M 3 User Guide, Command Summary and Programmers' Manuals can be found in the following locations:
| http://www.cpm.z80.de/manuals/cpm3-usr.pdf | User Guide |
| http://www.cpm.z80.de/manuals/cpm3-cmd.pdf | Command Summary |
| http://www.cpm.z80.de/manuals/cpm3-pgr.pdf | Programmer's Manual |
A good starting point is also:

Other than NextZXOS, CP/M and +3e/IDEDOS, your ZX Spectrum Next supports natively one more Operating System called esxDOS. This is especially helpful when running Eastern European software as the preferred method of storage is using TRDOS which esxDOS supports natively. Unfortunately the copyright status of some parts of esxDOS prohibits its inclusion in the System/Next™ distribution, but that doesn't mean you cannot install it yourself. esxDOS can be invaluable for personalities other than the Next Native one as it provides older model personalities with an easy way of managing FAT formatted SD cards. As is the case with NextZXOS, it too uses FAT as the primary filesystem and thanks to NextZXOS' design, it can therefore co-exist on the same drive without clashes.
In order to install esxDOS you need to do a few things first:
