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*.  ``` WordStar, CP/M Edition, Release 4 O P E N I N G M E N U D open a document L change logged drive/user N open a nondocument C protect a file P print a file E rename a file M merge print a file O copy a file S check spelling of document Y delete a file I index a document F turn directory off T table of contents Esc shorthand X exit WordStar R run a program J help DIRECTORY Drive A ALIAS.CMD CHAPTER1.DOC CHAPTER2.DOC CHAPTER3.DOC CONFIG.LBR DIARY.DOC DISK DISK1 DISK2 DOCFILES.LBR FCP.LBR HELP.HLP HLPFILES.LBR HOMONYMS.TXT HYEXCEPT.TXT LSH.WZ MAINDICT.CMP PATCH.LST PATCH4SK.HEX PATCHSK.SUB PRINT.TST RCP.LBR READ.ME README RELEASE.NOT RULER.DOC SAMPLE1.DOC SAMPLE2.DOC SAMPLE3.DOC TABLE.DOC TCAP.LBR TCJ.INF TCJ25.WZ TCJ26.WZ TCJ27.WZ TCJ28.WZ TCJ29.WZ TCJ30.WZ TCJ31UPD.WZ TCJ32.WZ TCJ33UPD.WZ TEXT.DOC WSINDEX.XCL Z3PLUS.LBR Z3TCAP.TCP ZFILEB38.LZT ZFILER.CMD ZHELPERS.LZT ZNODES66.LZT ZSYSTEM.IZF "VERS""1.02F "Z3PLUS ""C"1988 ``` *Fig. 31 – ZX Spectrum Next CP/M running WordStar 4* ### Further information 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-cmd.pdf	Command Summary

A good starting point is also: **http://classiccmp.org/cpmarchives/** which links to many more useful sites, collections of software, manuals, magazines and much more. ### Preparing your ZX Spectrum Next for esxDOS 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 *esxDO*S 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:
