What kind of file is it? Word, PDF, JPG, mp3, etc.? I just tried this on a PDF file I created from scanning a document (a Bill) and it worked perfectly on my W10 Desktop. I also have v1607 build 14393.693 same as you. However, I've seen this particular problem before. Sometimes, it's repairable, but usually it requires a W10 Reset or W10 Reinstallation from Factory Recovery Media *if you have it or can make it from a built-in Utility such as
Acer e-Recovery or
Dell Recovery Assistant*. You can right click on the properties of your file and make sure your file has the correct file extension. The other thing that's worked for some forum users posting this problem in the past has been to use the Microsoft Fixit tool which you can download for free from the Microsoft site and select
"repair Cortana" option and see if that fixes it. Since your W10 File Explorer is finding the file Ok and Cortana (W10 Search) is not, it's probably a Cortana configuration failure or simply Cortana corruption.
Last ditch resort might be to scan for viruses/malware with whatever AV program you have currently installed on your W10 computer. Such as Norton, Avast, McAfee, TrendMicro, etc. There are now new viruses out that specifically target Cortana and
DISABLE HER! Scan/remove all viruses found by your primary AV program. Reboot & Retest your search. If it works ok then, you successfully removed the Cortana-virus and are back in business!
If this 1st AV scan/removal doesn't do it, you'll need to check further by downloading the Free
MALWAREBYTES antispyware program available from
MALWAREBYTES.ORG. Make sure to check the
"check for RootKits" checkbox. Then Scan/removal all spyware viruses found. Reboot & retest your file search again. If this fixes it, you had a Spyware virus attacking your Cortana as I describe above, and you're good to go!
If neither the
AV or
MALWAREBYTES scan/removal processes fix the problem, nor the Microsoft Fixit tool; you probably have a virus that was programmed to destroy your Windows system files or registry settings, and there is no recovering from that usually, unless you are willing to pay hundreds of dollars for a Computer Pro to fix it for you.
At this point, you'll need to
BACKUP ALL YOUR PERSONAL DATA FILES (LIBRARY FOLDERS) TO EXTERNAL MEDIA, IF YOU HAVE NOT DONE SO ALREADY, OTHERWISE YOU MAY SUFFER IRREVERSIBLE DATA LOSS!!! Next, take a look at the Software repair section of my Troubleshooting Guide to assist you with Resetting or Reinstalling your W10. You may also want to do a
CLEAN INSTALL of your W10 if you had upgraded your PC from an earlier version of Windows, such as W7/W8/W8.1. You won't need to enter your W10 license again, as if you upgraded it earlier, the license key will be stored on the Microsoft Activation Servers and as long as you have an Internet connection to this PC, it will recognize it automatically for you!
