Deleting 374,707 items ... 99% complete <-- what is the remaining 1% ?
Time remaining <-- empty, why ?
items remaining: 0 (o bytes) <-- why does it never finish delete operation ?

Note: with delete command - as with most Windows 10 commands - verb tenses are wrong, why ?
Example 1:
deleting <-- preparing to delete would be correct
deleted <-- completing deletion would be correct because operation continues even after "100%"!

Verb tenses were mostly wrong also in Windows 8 - why ?
whereas in Windows 7 and earlies Windows versions they were ok - why ?

Example 2:
copying <-- preparing to copy would be correct!
copied <-- completing copy would be correct because operation continues even after 100% has been copied!
