MS Word Dictionary Backup - Unknown File in Backup Folder

Unknown File in Word Dict Backup Folder ,  2014 December 14

I am using Windows 7 Pro 64 bit and MS Word 2010 (as part of Office Pro 2010).

Whenever I add words to my MS Word 2010 Custom dictionary or Exclude dictionary, I back up those dictionary files to another folder. I noticed that in my backup folder is also the following file, and I don't know what it is.

CMAdj.9.bin

I can look at the properties, but I still don't understand. It is a BIN file that opens with "Windows Shell Commor" (not "command"), is 1 KB in size, but I don't know what it does. The file modification date is different from the file modification dates of when I first backed up my MS Word dictionaries to the backup folder.

I don't have an "open with" command available when I right-click this file name. So I cannot view it in Notepad. (Btw, is there a simple way to add an "open with" command to always show on the right-click, context/command, menu -- without editing the registry?)

And since I don't know what it commands, I don't want to click on it to run it. I could simply delete it, since it's in my backup folder and therefore cannot be integral to operating any program. If I copied it there, I don't know from where I got it.

Does anyone know or have a guess as to what this file might be or does? Could it have copied along with my MS Word dictionaries when I backed them up?

When you reply, please use simple English because I don't understand a lot of techy words.

Thanks.

I find the same file in my UProof folder. I opened it with a hex editor to see its contents. Along with a small group of other bytes, it contains two pairs of words/phrases:

any more         anymore

their                 there

I believe this may be a file downloaded by a Microsoft update to add these pairs to the "contextual spelling" feature, which highlights words in your document that might be misused. You can turn that feature on and off by going to File > Options > Proofing and checking/unchecking the box for "Use contextual spelling".

Although the .bin extension often indicates a command-type file, in this case it merely indicates a "binary" file as opposed to a text file. If you try to run it, I believe nothing will happen; at worst you might get a message saying that it isn't a valid command file.
