Q: I will soon need to edit some fairly large files. How big a file is KEDIT able to handle?
A: In KEDIT for Windows, and in KEDIT 5.0 for OS/2, the maximum size of the files that you can edit is limited only by available virtual memory. This consists of the total RAM installed on your system, plus the size of your swap file, minus the amount of memory being used by the system itself and by other applications that you are running. In practice, this means that you'll seldom encounter memory limits, even with very large files.
Note, however, that when you are editing files that will not fit within your machine's physical memory and must be paged to and from disk by the system, performance of some editing operations will degrade.
KEDIT 5.0 for DOS has tighter memory limits--it uses XMS or EMS memory, up to a maximum of 16 megabytes, to hold your files. So, depending on the amount of XMS or EMS memory you have configured, and allowing for some internal overhead in keeping track of your file, KEDIT for DOS can edit files of up to about 13 megabytes.
