First thing I would suggest is ...

to select ONE of the files and delete the .dcm portion and see if it now opens (sometimes malware will add extensions). If it does not open add the .dcm file extension back onto the file name.

If the files are on Western Digital MyBook drive the DCM extension was added by Western Digital Mybook software, at least according to this website -

If the first thing works just get busy re-naming files. If it didn't work here is one converter (not free) -

.dcm file extension

i tried the first suggestion right away - didn't work.

and it is a MyBook backup, but i don't know why it adds the extension if it makes the file unusable (unless it owns one of the converter programs!) i wonder if i can open the files by plugging MyBook back in...
if not, will give the other programs a go.
thanks for the input.

using the MyBook software to RESTORE the files. That is probably your best bet.

Whatever you do trying out converters, work with COPIES of the files and not with the originals.

you cannot convert the *.dcm files as they are information files that contain the actual path, the creation date and time of the file, and the checksum value (which is only for Memeo AutoBackup's internal use) are stored in the .dcm file.

This link should help you to actually RESTORE the files you want from the backup on your external MyBook drive.

and the input (i agree, Kees)
- if only there were some way to simplify, streamline all the info that we try to preserve!

I hate those backup programs ...

that convert their input data to some proprietary format. In my opinion, nothing is better than just a plain copy. Only compressing with a standard algorithm (like zip or rar) is acceptable.

How to convert DCM files
by moxieman / September 25, 2016 7:42 PM PDT

Found very simple way to convert DCM files to ,JPG files. Download, free, "Total Image Converter". After install, point converter to file location via File listing on left, and in a
blink, all the files are in a .JPG format. You can look at each photo one by one. Saving it
is easy but it converts it all to a .PDF file which is okay. I opened all the DCM files from
my MRI and looked at them. Kool.
