Windows 10: Can someone please tell me what these files are and if they are safe to delete?

I found these files, are they safe to delete? I'm trying to free up space.

:)

 

Can I delete this unknown file safely?

Well then simply erase (Shift + Del) the $RECYCLE.BIN folder of that drive, I just find it odd that Windows doesn't pick up the drive's recycle bin when you connect it.
And yes it's completely safe to delete the whole $RECYCLE.BIN folder, it wont affect any of the other files/folders on the drive, and whenever you delete (Del) another file it will be re-created.

 

Can I delete this unknown file safely?

I'm currently tidying up my external Western Digital HD and I ran Treesize to see where everything is.
I came upon the highlighted file and sub files, below, which is hidden, but I wish to get rid of it as it contains 20Gb of data.
It contains files, such as films, which I had previously deleted and which I thought had gone but which appear to have gone to some hidden deleted file.
I presume it would be safe to delete this whole file and sub file via the Treesize application without it affecting all the stuff I want kept on the HD?

Tom.

 

New FF - passwords

Hi:

If that setting is already enabled, then I suggest as the next troubleshooting step might be Mozilla Safe Mode (not to be confused with Windows Safe Mode)):

• Please report back and let us know the outcome, as it will dictate the next steps.
• Also: please tell us what AV/AM/firewall programs are you running on this system?

Thanks,
