Cannot overwrite remote file

2015-11-19 20:39

Error Message:

Cannot overwrite remote file

Using PowerShell and WinSCP.dll.

How can I script WinSCP to overwrite remote files on upload/put using PowerShell?

Is there a transfer option?
Or what is a simple PowerShell script to delete remote file if exists?

Thanks,
Jake

WinSCP overwrites remote files by default.

Please attach a full session log file showing the problem (using the latest version of WinSCP).

To generate log file, set Session.SessionLogPath. Submit the log with your post as an attachment. Note that passwords and passphrases not stored in the log. You may want to remove other data you consider sensitive though, such as host names, IP addresses, account names or file names (unless they are relevant to the problem). If you do not want to post the log publicly, you can mark the attachment as private.

I'm getting permission denied.
I also get buffer optimization messages and "0 seconds" messages.

There have been some other issues around preserving timestamps (which I have set to false, and can't do true...not sure why).
I've tried various SendBuf sizes, and it doesn't change the buffer optimization message.
Not sure where I can change the "timeout=0" parameter. My sessionOptions.Timeout=15, not 0.

I don't have problems using the GUI, just from PowerShell. It would be nice to use the same GUI config in my PowerShell, and I'm checking to see if this can be done.

session.PutFiles(path, session.HomePath + "/", ...);
