Add Comments to files in Windows Explorer

I have many files (mainly .pdf) that I need to add a User comment to in Windows Explorer so that I can identify files that I have processed in our database from files that I still need to register in the database (The folder is constantly being added to)

I have added a comments column in Windows Explorer but cant seem to find where to enter the comment.

Also if this is possible am I able to add the same comment (it can be just a tick box) to multiple selected files?

An add-on utility would be OK if one is available.

Any suggestions?
Thanks

I use this with .doc files. maybe it works on a few other extensions.
You have to first create the "comments" column in the view - you seem to have done this.
Right click the (.doc) file and select the details tab.
In the "comments" line, move the cursor over to the far right - yuo will see a small blue outline there, and click.
Write your comment.
P.S It does work on multi file choice - in my case, all .docs.

Thanks Dave, it doesn't work with .pdf files.

The "Comments" line doesn't show in the Details tab

Sorry M8. I have browsed and browsed. No success. I even tried a few alternative explorers, but they all piggy back the original, with the same functions.

I had the same problem trying to add explanations to files I had downloaded from Astronomy Picture of the Day until I found this nifty little app

It will solve ALL your problems!!

No need to go to HowToGeek; we have "Take Ownership" available in our Freeware DB. But I fail to see how having Read/Write/Delete permissions would have any effect on what Furn is trying to do.

Only certain file types allow comments and permissions does not change the file type.
