Sorry, I do not understand, how is this related. Why could you use rm *.filepart only if you could also move the files?
Anyway, see Moving local files to different location after successful upload.

Also, I'm not sure if by "automically" you mean "automatically" or "atomically".

Dear Martin,

thank you for your answer.

I'm thinking about how this would work in my scenario.

Is there an option to automically move the files on source to another location, after they are transferred successfully?

If yes, I could work with the mentioned rm command.

No, there's no "delete" option. But you can delete the .filepart files before the put:

Or as your server apparently does not allow the resume, turn it off in the first place:

Dear Experts,

I'm using WinSCP 6.3.4 on Windows Server 2019.
I'm transferring data automated via script from my server to an FTP server inside Microsoft Azure.
Sometimes it happens, that the connection is lost. Therefore I have a reconnect, which retries the connection and continue the transfer. However I get the following error message after reconnection:

The File XXX.csv.filepart can't be overwrited.
General Issue (The Server should provide an error message).
Error Message from Server (en): BlobAlreadyExists: The specified blob already exists.

After that, the following options are available:

delete, cancel, retry, skip, skip all

In batch mode, I can only choose between Cancel or Skip. Is there an option, to choose Delete instead?

I use the following commands inside my script:

Thank you so far.
