Very strange situation in Windows when delete files

[brave2heart4u]

Hello, I am very disappointed, I need help from you, if possible. I have a Windows computer and I wanted to delete many files from an archive located in partition D, my Windows has two partitions, C and D. There were around 80 thousand files in that folder, in several subfolders and to select them only by files and without folders, to check them, I used folder explorer .*. as a search option, if you know how to do this or what it means, otherwise I'll explain again, English is not my native language, sorry . And I right-clicked and deleted them with a program called File Shredder, with a blue trash can as an icon, but I noticed that instead of deleting files from that folder that I wanted and ask program to delete from/ in partition D, it showed me instead that it started deleting automatically my Desktop files from partition C, without selecting that or asking to do that deleting operation. How could this happen?
What happened and why, in this situation?
What can be done in this case?
How is it possible to delete from the desktop when I was in partition E and I wanted to delete the files from there, which had nothing to do with the desktop in partition C.
How can I recover deleted data from the Desktop?
How can I see what was deleted recently from the Desktop or from Windows?
What caused this error?
Does this program called File Shredder have a log somewhere?, so I can see what it deleted last time or when it deleted that data from the desktop? Or where can I see in Windows what was deleted last time from the computer?
How can I see exactly everything it managed to delete from the Desktop? Or maybe from other parts, because I was not able to see everything it started to delete, until after a while when I looked more carefully and saw that the path that program deleting files, was C and Desktop, not that folder in partition D which/ where I selected inside files for deleting process, using this program.
And can I still recover the lost data? And if so, how can I recover my data deleted from the desktop by this application?
And is there any program that will prevent me from deleting any file or folder in the future by mistake? Thank you very much! Excuse me for the questions, but I am desperate and sad.

I assume this is the program;
File Shredder

80,000 files??
Kinda hard to believe that amount. Or was it 8,000 which is still kinda high?
Why did you have to use this File Shredder? Where these personal files (financial etc.)?

I've NEVER 'stored' anything on the Desktop in the past 25+ years of tiring to deal with M$, way too easy to get deleted.

Did you have these 'linked' somehow between D drive and the Desktop?
Whatever was on your Desktop, were those actual 'files' or links to folders that had the files?
What folders' did you have these in? Were there multiple folders?
How many layers deep were they or were they in the Root of D drive?
