Windows 10: my music files that I made with Mixcraft 7 have disappeared

I am a music composer working on 2 computers. On this computer I cannot find my mixcraft files. Please help me

:)

 

Downloaded files disappear


When you download a file through any browser, there's an option somewhere to 'Open Containing Folder.'

In Windows, to find a file you have downloaded...

1. Open your personal folder by clicking the Start button and then clicking your user name at the top of the Start menu's right pane.
   
2. Double-click one of the following folders:
   
   • Downloads
     
   • Documents
     
   • Pictures
     
   • Videos
     
   • Music

If you do not see the file you are looking for, but know its file name, you can search for it by following these steps:
To search for a file you have downloaded...

1. Click the Start button
   
2. Type all or part of the file name into the Search box.
   The file you are looking for will appear in the list of results.

 

Music has disappeared


Mm, could you explain a little more?

For example, have you just upgraded to Win 10 and you've lost some files? Had an update? Done something to one of your disks?

Where was your music? On what device or where on your PC's disk?

Do you have any backups?

Please tell us what happened step by step from having your music to when you realised your music had gone.

You said (in your 2nd thread):
I have searched for titles on 'My Stuff' & it's there in gobbledegook,

Please use explorer. Navigate to the folder where you expect your music to be.
Post one or more screenshots of what you see, showing the files and folders. (Using the icon above to the left of the video icon)

What do you believe has changed if anything?
Thanks.
rationale: we don't know if indexing has been set up appropriately so let's first check the music is present as expected

 

The option converting m4a files to wma files in windows 10 is disappeared

• What app are you using to convert the files?

I don't use any app to convert the files. I just copy the m4a files from my music folder. Then I paste the m4a files in my android phone drive that connected to my laptop. Then a windows pop-up that shows the option converting m4a files to wma files appears.
You can see the windows pop-up in below picture. Now the windows pop-up is disappeared.

• When did the issue start to happen?

I found this problem last week. However, I didn't convert m4a files to wma files since May, 2017.

• Were there any changes made to your device prior to the issue?

I updated windows several times prior to the issue.

• Have you done any troubleshooting steps so far?

I haven't done any troubleshooting steps.
