I tried to write a file directly from DOSBox console: Copy code to clipboard 1 copy con stop.txt Then I wrote Ctrl-Z and it did not work. So I closed the window of DOSBox. Was the file closed upon closing the window or my file system is harmed? Thanks in advance!

Thank you very much. Good advice. Unfortunately , I hoped that the name is different and wanted to put "MSCD001" there. (If the name were different the change could make executable my Software Toolworks Electronic Encyclopedia...)

Otherwise an application dependent error occurs. How to avoid it in DOSBox? Thank …

It is application dependent error. I don't know how to remove it. Thank you.

In application's manual is written that this error is a result of missing settings in CONFIG.SYS (missing CD-ROM driver name or missing CD-ROM device name next to it) or MSCDEX without CD-ROM device name next …

Please, don't you have any idea how to launch the mentioned encyclopedia in DOSBox? It wants to know the driver of CD-ROM drive in CONFIG.SYS together with device name as well as MSCDEX with the identical device name otherwise it generates an error (can't find local CD-ROM drive). Maybe it is …
