"Access is denied" for local delete during synchronize

Can't for the life of me suss this one. Simple synchronize script to compare to a remote ftp server, updating the local machine with new, updated and deleted files/folders. Except it fails to delete local folders with Access is denied. I run the script as administrator, or not - same. The permissions for the folder are inherited, and include everyone=full control, current user is owner. If I manually delete the folder, then manually create it (or manually create a new folder), the manually created folder will delete. I have thoroughly compared permissions between existing and newly created folders - identical. The existing files/folders were originally copied there via another ftp client from the same remote ftp server source. The script is set to run monthly to update the local from the remote server, and works well - except for this annoying anomaly.

Files get deleted okay, but not folders - unless I manually created it.

Both client and server running Windows 10 Pro build 1709, not on a domain. Current user is an administrator user.

Can anyone shed some light for me?

So when you are logged in with DITSUPPORT\DIT account, can you delete the folder with a simple command-line rd command?

Very good question, Martin - I haven't tried to delete from cmd, only explorer. Now having tried as you suggest, it says access denied. When I create a new folder manually in the same location (using explorer), permissions from the explorer properties security are identical, but using attrib /d /s, the "rogue" src folder displays as R, whereas the manually created folder does not - no attribs returned for it. Obviously that is the problem

You have given me a good lead to follow, now to find out why cmd attrib is different from the explorer gui security properties.

Thanks again Martin, for the lead. Still don't know why the difference, but I have solved my problem by putting an attrib -r command in my batch file that runs the winscp script. Works a treat.

Cheers.

Sorry, thought I was logged in when I posted the previous replies.

Cheers.

Thanks for sharing your solution.
