BC Script AND T attribute

[wmanger]

When I use the script below, any files that the script finds have a T (temporary) attribute and are then un-downloadable from any SFTP client. Is there something that I am missing? How is the script able to alter attributes on a SFTP?

Script:
-------------------------------------

log verbose %LOGS_PATH%\backup-%BACKUP_NAME%.log

load %BACKUP_NAME%

filter cutoff:<4days

select rt.files

folder-report layout:summary output-to:"C:\bcout.txt"

Running the above script shouldn't change file attributes on your SFTP server.

What SFTP server software is running on your server?
What operating system is the server running?

Are any processes running on the server that might be changing the same files?
