ERROR_NOT_SUPPORTED: The request is not supported. [SetFileInformationByHandle(FILE_ATTRIBUTE_READONLY)]

Log and PML #6 sent to you.

Perfect! I can finish the implementation now: The following version should fix all the issues discussed in this thread and should work for tbain98 as well ...

We're getting somewhere. The ERROR_NOT_SUPPORTED seems to be an issue specific to setting file attributes, but unrelated to file times. Question is, is it FILE_ATTRIBUTE_ARCHIVE in particular, or other attributes as well? Let's test: https://www.mediafire.com/file/20ajqgo815olcmz/FreeFileSync_12.6 ...

I've also run and sent a trace (#4) with log using this newer version too, in case it helps.

Looking good! Finally we're at "SetFileInformationByHandle(FileBasicInfo): ERROR_NOT_SUPPORTED" as reported in the very beginning of the thread! Here's a version that tries to work around. It might ...

Alas, this is as bad as expected. The "DeleteFile" is also fooled by the stale cache-response ERROR_FILE_NOT_FOUND.
But: We might be able to get the server to return accurate information via CreateFile's OPEN_ALWAYS disposition. This is a potential write-access, so it can't be cached: https://www ...

I've seen the further comprehensive replies above (thanks tbain9824!) - let me know if a further trace from my end would still be helpful? Background_Basil_945, 24 Jul 2023, 06:49

Yes: In tbain9824's case we're tackling another problem that happens before the issue discussed with you. Zenju, 24 Jul 2023, 09:03

Run and emailed to you (#3). Thanks again!

This is the second error I mentioned, and is expected. But I don't know how it's possible that setting file attributes could fail with ERROR_NOT_SUPPORTED. Can you send me a PML log file for this case, too?


Thanks Zenju. Apologies for the delay, been tied up over the weekend. I've seen the ...

Thanks Zenju. Tried the beta but the same issue occurs.

Cannot write file attributes of "\\AX86\Music (at MX500)\Big Wreck\FLAC\Albatross\01 - Head Together-7aed.ffs_tmp".

ERROR_NOT_SUPPORTED: The request is not supported. [SetFileInformationByHandle(FileBasicInfo)]

Thanks Zenju - both sent!

Thanks Zenju.

1.Full error message:

2. I can't see any .ffs_tmp files, and hidden ...

Thanks Zenju, trace run and sent to you.

Thanks Plerry, but it appears to be an issue with FFS.

I can copy and paste in windows explorer when authentication is enabled, but FFS generates the above error.

FFS will work fine! FFS does not encrypt anything or put it into a proprietary format. It is a really advanced copy/paste utility, with other features as well xCSxXenon, 13 Jul 2023, 13:16

This is exactly the reason I use FFS and not a backup utility.

> ... I will disable password protection for syncing!
Not the safest idea.
Simply use the Windows Credential Manager to save the user/password for your NAS.


Thanks - you're right, but the sync doesn't work if authentication is enabled. I only temporarily disable to sync. Hopefully to be fixed ...

Hi all. I'm facing the same issue on 12.2 syncing MP3 music files from an NTFS NVMe drive to an NTFS NAS SSD. Is there any further update?

EDIT: found the issue for my situation at least. Access to my NAS (via SAMBA share on ASUS AX86S router) is restricted with username/password authentication ...
