Help when copying from win10 to raspberry pi400

[luckyluca]

I'm getting errors when copying from Win10 to the pi400 (with default options):
Often, I get the following but files do not exist of course:
"D:\retropieStuff\luca\roms\naomi\alienfnt.zip" to "\\PLAYBOX4\roms\naomi\alienfnt~2089.ffs_tmp".
ERROR_FILE_EXISTS: The file exists. [CopyFileEx]

More recently I also got, when adding an additional option the following too:
Cannot write permissions of "\\PLAYBOX4\roms\naomi\azumanga".
ERROR_PRIVILEGE_NOT_HELD: A required privilege is not held by the client. [SetFileSecurity]

Any idea what might be going wrong?

Many thanks

Thanks for getting back to me so quickly.
The second error is relatively straight-forward to solve, as the option can be left disabled.

The first error, is the solution in the link?
To be clear, the copy fails, this is not a clean up issue, several files are not copied at all.

I'd be more than happy to wipe any extended attribute from my ntfs files ahead of the copy, I've been having but trouble with ntfs attributes when copying to the pi400 over samba and wifi.

As a workaround for some files, I moved them to a fat32 partition and back to ntfs, thus wiping any odd attribute. Could you suggest a utility to strip any unwanted attributes from ntfs files, that might help getting FreeFileSync to work?

Thanks again
