32 MB Files Are Not Always Handled Correctly in 4.00 or 4.01 PSS ID Number: Q49240 Article last modified on 07-14-1993 PSS database name: O_MSDOS

|- Microsoft MS-DOS operating system versions 4.0 and 4.01|
Microsoft has confirmed that 32 MB files are not always handled correctly in MS-DOS versions 4.0 and 4.01.This problem does not occur in later versions of MS-DOS.
The following is one example of this problem:
A system is configured with a hard disk that has a partition size larger than 32 MB with MS-DOS Version 4.01. The correct file size is not reported by the DIR command when a file that is nearly 32 MB in size is concatenated with another file using the COPY command. The file being added must be small (1K), so that the end result would be a larger file still near the 32 MB size. Some sample file sizes are listed below:
Issue the following command to concatenate the two files:
C: COPY 32MB.FIL+SMALL.FIL LARGER.FIL
After the COPY command is completed, the following file sizes are reported with the DIR command:
File Name Size ——— —-
32MB.FIL 33,554,000 bytes SMALL.FIL 101 bytes LARGER.FIL 33,554,000 bytes
Additional reference words: 4.00 4.01 noupd
