Question:
What is the largest file the Microsoft Editor can load?
Response:
The size of the file is controlled by the operating system, not by
the editor. The editor will read in a file of any number of bytes;
however, you are limited by the temporary file space.
The size of the drive pointed to by the TMP variable is the limiting
factor. Because TMP often points to a (relatively small) RAM drive,
such as VDISK or MS-RAMDRIVE, this is the most common file size
limitation.
A safe rule-of-thumb is that your TMP drive may need to be up to
two times the size of the file being edited.
The maximum number of lines a file can contain is 0x7FFFFFFF, but you
will run out of disk space before you have too many lines.
Both MS-DOS and OS/2 currently limit disk size (hence, file size)
to 64K sectors, which normally is 32 megabytes.
