Hi,
I have two large binary files, 3.99Gb and 3.79Gb. The
console command for this is,

Copy /b a.xxx+b.xxx combin.xxx

But this command gives an error that not enough disk
space. The free space available is 21Gb. Microsoft
Support says that MS-DOS 16-bit environment does not
support such large files and so the error.

The Catch - Any ideas of how to append a 3.79Gb binary
file to 3.99Gb binary file.

Regards,
Ahmed.

You don't say what file system. NTFS or FAT?

FAT and FAT32 are limited to a maximum 4GB file size.
 
Hello yes, but you have to convert your disk to ntfs, be aware that if you
have dual boot be sure to check where are the files because if you convert
your fat32 partition and on there having windows 98 or me it will become
unusable... start-run-cmd and then convert c: /FS:NTFS or whatever unit you
have... you can also see more option by doing convert /?
 
hey
sorry for late reply,
I have fat32.
does this mean there is nothing i can do to append a
3.79Gb file to a 3.99Gb file.
You are correct. You cannot do what you want with FAT32. Convert your
file system to ntfs if you routinely need to work with very large
files.
