Thanks for your feedback.

Regarding the slashes: That cannot be any different in PutFileToDirectory. Though, you should use forward slashes for remote paths, not backslashes.

Regarding what the methods return (I assume that's what you mean by "return code"): They return the same information basically. Except that PutFileToDirectory throws an exception on errors, while PutFiles does not.

Resolution: PutFileToDirectory is working fine, except that the return code is less convenient than PutFiles().

We found the problem with PutFiles - We needed to escape the slashes in the destination path, as in \\root\\filepath.dat.

Everything's good, thanks Martin. I'll get another donation out, during the summer.

I'll take your word for it, and will assume I'm doing something wrong. For now, in order to move the project forward, we have to use PutFileToDirectory().

If we need to transfer multiple files to a server at some point, we'll revisit this.

T & R,

The PutFileToDirectory(localPath, remotePath) basically does (a C# example, VBS would be slightly different):

PutFiles(localPath, RemotePath.AddDirectorySeparator(remotePath))

Nothing fancy. So if PutFileToDirectory works, the PutFiles with the remote path ending with a slash must work too.

Ok, I reproduced the error with PutFiles(). It says that it can't overwrite remote file, and refers to the folder without the slash (even though it was supplied the destination folder with the slash), thus:

Cannot overwrite remote file, '/destinationfolder'.$$

That's the same error I received earlier, when appending a slash. So, at least right now, I have to use the PutFileToDirectory function. That's ok, since we're uploading one file at a time anyway.

I thought I had tried with a slash in front, but there was still an error. I guess falsely concluded that the slash was the problem.

Ok, now that everything else is solid, I'll try with the slash, and then refactor sections into functions whenever practical.

Setting PreserveTimeDirs to 1 cannot help in this case. The IgnorePermErrors can work as a workaround. But the right way is to set the TransferOptions.PreserveTimestamp to False:

Destination folder is enough, but it must end with a slash.
See https://winscp.net/eng/docs/library_session_putfiles#remotepath:

Full path to upload the file to. When uploading multiple files, the filename in the path should be replaced with operation mask or omitted (path ends with slash).

I'm getting one of those 'but error occurred while setting the permissions...' error, but that setting is simple.

I think we're all set, thanks.

Didn't set up the logs yet, but the error description from the module was revealing enough. The source filename was spelt wrong.

Now there's an odd error about a duplicate filename, even though there are no files in the destination folder. It almost looks like the destination folder is being interpreted as a file name rather than a folder name. But I don't know that for a fact, yet.

Cannot overwrite remote file '/InFolder'.$$

Press 'Delete' to delete the file and create new one instead of overwriting it.$$
General failure (server should provide error description).
Error code: 4
Error message from server: MailboxSystemProvider.openFile(S,UI32,SFA) Invalid handle - Duplicate file and dir path

Common reasons for the Error code 4 are:
- Renaming a file to a name of already existing file.
- Creating a directory that already exists.
- Moving a remote file to a different filesystem (HDD).
- Uploading a file to a full filesystem (HDD).
- Exceeding a user disk quota.

Yep, that was definitely a problem, thanks.

Even with the logic errors, the transfer still gets attempted and fails. Now that the error check is corrected, it still fails.

So I need to set up the standard logs, to see what's happening from Winscp's vantage point.

I think that's covered here https://winscp.net/eng/docs/logging , but there were some other forum posts about it, so I'll read those first.

Re: Transferring not generating a VBScript error, but IsSuccess() returning false

2021-05-21

I guess the problem is that you test Err.number > 0, while it should be <> 0, as the error code is actually negative.

See https://winscp.net/eng/docs/library_com_wsh#vberror

In the morning, I'll try setting the SessionLogPath, per
https://winscp.net/eng/docs/logging

, in order to generate the standard WinSCP logs.

I think I'm almost there. Can you check the code? Is there that stands out as a potential problem?
