Verifying signatures not working

Hi every when i try to import keys i keep getting this message

gpgv: can't open 'Downloads\\tor-browser-windows-x86_64-portable-13.0.1.exe.asc': No such file or directory
gpgv: verify signatures failed: No such file or directory
PS C:\Users\jon\Downloads> 

this is after following instructions and copy and pasting the commands of the website. I get the same results on everything i try to download .can anyone tell me what i am doing wrong please and thankyou.

this is the command from the kali.org website

$ gpg --keyserver hkps://keyserver.ubuntu.com --recv-key 44C6513A8E4FB3D30875F758ED444FF07D8D0B
gpg: key ED444FF07D8D0BF6: "Kali Linux Repository <devel@kali.org>" not changed
gpg: Total number processed: 1
gpg:              unchanged: 1
$ gpg --verify SHA256SUMS.gpg SHA256SUMS
gpg: can't open signed data 'SHA256SUMS'
gpg: can't hash datafile: No such file or directory

Welcome @dmart!

It seems like the key import was successful, but the verification of the signatures failed because of the wrong path (No such file or directory). You need to pass the correct path of the signature file to gpg.

ok thankyou i will try that
