One Drive File: .849C9593-D756-4E56-8D6E-42412F2A707B

Thanks Paul. Yours is the first response I've understood! My pc doesn't appear to have been infected or affected, but I'm super cautious these days after having fallen for a very clever scam 16 months ago, which has resulted in me receiving a multitude of ****-mail.

If anyone sees teeth whitening ads from Spark Whitening or Bella At Home, DO NOT be tempted! The small print allows each of them to charge about £90 a month from your bank a/c, & to use your email address for whatever purpose they like.

If you exit onedrive the file disappears from the folder, load onedrive up again and it re-appears. It can't be that bad unless its hanging the sync, but I can't see how.

It does takes ages to process changes so be patient if you delete or add files for syncing.

Have had same feeling, doesn't seem to be causing any problems. Decided to leave it alone. I have it on 2 laptops but not on my tablet. Thanks.

Hi JW

Basically i agree with you on hidden files

BUT

something in very annoying with this new hidden file as it is considered bu Windows10 as a user counted file !

ie.

1. before moving to Windows10  i secured copies of all my files and (ie.)

• i had 4000 files in  C/User/username/OneDrive

-  and i had 4000 files on the saved location in the USB key

2. after Windows10 was installed  i discovered

• i have  4001 files (one file more) in C/User/username/OneDrive.
• Why?
• Then i discovered that this hidden file as considered/counted as a user file (directory properties)  and this is incorrect.

3. using Windows10

• if i save a copy of C/User/username/OneDrive (4000 files) the program stops and says : (see at the bottom of the picture below)
• hidden file is currently in use by MS OneDrive

and you just need to select "ignore" BUT the count of saved files is now 3099 files !!!!!!

• this confirms point 2)

Is it possible to inform Microsoft on this wrong qualification file on this hidden file ?

Best regards

I hate to be the one black sheep here, but I have a feeling that file is important as some type of sync file between OneDrive on the PC and online. It may be an indexer or some type of history tracker to ensure that files are synced properly based on where and when it is modified. Unless there is a problem like gil6269 had, in which case you can troubleshoot by deleting the file to refresh it, you really shouldn't mess with files that are hidden that you have no idea what it is... as long as your good and reputable antivirus application doesn't flag it as something bad and you don't have performance issues, who cares?? Just ignore it as it is clearly hidden for a reason.
