delete store.vol?

Hi, not sure what Unistore is, but this suggests
http://answers.microsoft.com/en-us/w...7f7e987?auth=1

it's something to do with universal apps cataloguing (E.g. Groove music player, Photos).
If so, simply deleting it would mean it's going to be recreated, I'd guess.

Not too many finds for a search on Unistore or Unistoredb.

It would be interesting if you can tell us if this is true- have you configured these for cataloguing- if so, how many items are catalogued, and is the file deemed 'not in use' if you stop any cataloguing.

Here's another MS answers forum posting that seems to suggest it's safe to just delete that file: http://answers.microsoft.com/en-us/w...950f91b?auth=1.
HTH,

Mine's 6.1Mb. I don't use those apps and haven't configured cataloguing - did you allow that at some point?

Safe Mode or booting from e.g. Win 10 install medium and deleting it should both work. However, I found nothing locking it.

Good that you took precautions with the image - too many don't. Note however that there are repeated experiences of unreliability and problems using Backup and Restore images. 3rd party disk imaging is seen by many experienced members here as
a. more reliable
b. much more flexible and feature-rich

E.g. Macrium Reflect (free/commercial); Veeam Endpoint is also interesting.

E.g. when I launch Groove Music:



Note 'we are watching' - i.e. an index or catalogue will be built from wherever you tell Groove M to look for music- presumably so it can present your files in a format readily accessible to you to build playlists for Groove.

That implies it is watching folders containing music files and updating its own record (collection) of what's in them. Nothing to do with Windows search indexing.

Note I have nothing of my own in the default Music, Photos, Videos folders, so there's no chance the catalogue/collection maintained by MS apps will be significant. That's good, as my 40Gb+ collection of music on another partition is under my control, not MS's.

That's not the only reason I keep my data off C: of course!

Photos: here, think albums + collections.
8. Auto albums

Return to the main screen and click the Albums button on the left to switch to Albums view. Photos will go through all the folders in your Pictures library and try to group related shots together into albums, = processing/cataloguing- building a database- providing you with an alternative way to browse your collection.

Click an album title to view the photos inside, which are arranged beneath the main header image. Keep an eye out for an 'Add or remove photos' button at the bottom of the list – click this and you'll see similar photos that haven't been selected for the album, allowing you to include them if you wish (or remove photos from the album that aren't a good fit).

MS by contrast is notably brief, minimalistic:

Note: nothing unusual about this- some 3rd party photo & music programs offer it. Point is, here it's undertaken automatically- unless you know about it. Personally, I want to choose whether to have such things done.
