One of the strange things is that it is in your K partition. Is that your OS partition.

yes its os partition but not win 7 its for win 8 which i recently installed this folder was there before

they seem to be my very old files -\- i renamed this drive letter long time ago

Looks indeed very much like residues from a former windows installation. Probably safe to just go ahead and delete the whole folder, if it won't delete it's an ownership issue. So, how to delete... not showing up in Explorer with 'Show hidden files, folders' on, & 'Hide protected operation system files' off ?

i take the ownership as admin (full access) and still when i delete them nothing happens

You probably can only delete those with a reformat of the disk.

maybe but its the last thing to do ...

Boot a live Linux flash drive or CD, see if you can delete from there.

See whs's tutorial here: Emergency Kit - save your files from a dead OS

i think this is the solution:

1. Delete all restore points. Self-explanatory.
2. Reboot into Safe Mode. Self-explanatory.
3. Log on as Administrator . Self-explanatory.
4. Click the Start button. Self-explanatory.
5. Type the three letters cmd . This is one way to start the Command Processor (the Command Console)
6. Press Ctrl+Shift+Enter . This gives you the option to override the UAC restrictions.
7. Launch the Console session as an Administrator. Self-explanatory.
8. Type these commands and press Enter after each:
takeown /f "k:\System Volume Information" /a /r /d y . This command assigns ownership of the nominated folder to the Administrator. Type takeown /? to see the meaning of the various switches I used.
cacls "k:\System Volume Information" /e /t /c /g administrators:F . This command gives full access permissions of the nominated folder to the "administrators" security group (of which Administrator is a member). Type cacls /? to see the meaning of each switch.
rd /s /q "k:\System Volume Information" . This removes the nominated folder and all its subfolders.

i`ll try the live cd if it doesnt work or maybe format it later ...

i just wonder why windows explorer shows it empty and if its some kind of malware or something

-case closed !

thank you all
