That's not related to DJGPP... I'd suggest asking some questions in a
dedicated VirtualBox forum. So far, I've not seen anyone here indicate they
are familiar with VirtualBox.

I'm not sure how VB (VirtualBox, not Visual Basic...) affects your
situation. If VB allows to see your normal DOS directories, the progams
mentioned later will work for you. E.g., VB may have an option to "mount"
that directory virtually in VB. But, if it's like most other emulators,
you'll need to create an "image", i.e., a file that contains a filesystem
and files, and copy the directory to the filesystem in the image, then tell
the emulator how you want that image file to be recognized. E.g., you could
create a ramdisk in DOS, format it, copy directory to the ramdisk, then copy
the ramdisk as an image to a file, perhaps using Rawread.exe, or John Fine's
Partcopy.exe, etc. Then, you tell the emulator what to do with the image.
You also said the folder is on a CD, so you'll have to correctly setup
MSCDEX and your CD-ROM driver. If it's not a Joliet CD, i.e., ISO9660, your
LFNs may be incorrect, or missing for the DJGPP files. If it's a Joliet CD,
you'll need a special drivers to recognize Joliet in DOS, e.g., GCDROM.sys
CD-ROM driver, SHSUCDX.exe replacement for MSCDEX w/Joliet support, and
DOSLFN w/Joliet support.
IMO, the easiest method to copy a directory and it's subdirectories is
LCOPY. But, this is for normal DOS.
LCOPY is a LFN (Long FileNames) copy program written by Ortwin "Odi" Glück
(or Glueck). It's powerful enough that you can copy the entire Windows 98
system directory while in pure DOS without any errors, mis-named files,
missing files, with all hidden files, with correct SFNs and LFNs, dates,
times, etc. AFAIK, *NO* other tool can do that. I've tried all the DJGPP
ported GNU tools, PKZIP, and numerous others, etc. *Everything* except
LCOPY will fail on properly archiving or copying a Windows 98 system
directory. I.e., it works.
If you're in real DOS and not in a Windows DOS-box, you'll also need an LFN
driver to provide LFNs to LFN compatible tools. If the tools you use aren't
LFN compatible, they won't copy LFNs even with the LFN driver loaded. Jason
Hood's extended version of Henrik Haftman's DOSLFN works well.
You could also use the last version of PKZIP and PKUNZIP, if you can find
it, 2.50. It's easy to use also. It has options to archive and recurse
without compression. So, you just tell PKZIP to do that, then copy the
archive to where you want it, delete the first version, move to the current
version, then PKUNZIP it. As long as you're not doing a Windows system
directory, this will work just fine.
If you want or need to use DJGPP tools, you'll probably have to use DJTAR
and optionally GZIP. DJTAR is a LFN aware clone of TAR. So, you'll still
need DOSLFN. TAR packages the files into an uncompressed archive. GZIP
compresses them. GZIP is optional, but may reduce the time to copy the TAR
archive to the new location. You could use CPIO instead of TAR. That may
be easier. If using TAR or CPIO, you'll still have to use a procedure
similar to PKZIP, i.e., create an archive, copy it, delete the first
version, uncompress it.
If you were extracting from .zip files, not moving them, others here would
tell you to use the DJGPP port of Info-ZIP, i.e., UNZIP32, since it too
supposedly is LFN aware.

e.g., using DOSLFN and LCOPY:
DOSLFN
LCOPY/S/A/V C:\directory_to_copy\* C:\directory_to_place
/V is optional depending on your XMS client, or needed if you have don't
have one installed. That'll copy all files and subdirectories with their
LFNs. Note that LCOPY uses a single asterisk *, not *.* like most DOS
utilities.
I recommend that method.
e.g., using DOSLFN and PKZIP:
DOSLFN
CD C:\directory_to_copy
PKZIP -a -e0 -p -r ARCHIVE.ZIP *.*
COPY/V ARCHIVE.ZIP C:\directory_to_place
DEL ARCHIVE.ZIP
CD C:\directory_to_place
PKUNZIP -e -d ARCHIVE.ZIP
This is a good alternate.
Someone else can provide the TAR/GZIP/CPIO arguments, if needed. Obviously,
the utilities need to be in one of the directories of your DOS %PATH%
variable.
