RemoveFiles/PutFiles

Hello

<TL;DR>
RemoveFiles function is reporting it is succed (but the file remains not deleted), but PutFiles is reporting error 11 (File already exists).

It seems WinSCP application is deleting files in a right way.
</TL;DR>

We are using WinSCPNet version: 1.3.7.7441 (last nuget package)

I have this Session and transfer options (on this/failing Dev environment):
new SessionOptions
            {
                Protocol = Protocol.Sftp,
                GiveUpSecurityAndAcceptAnySshHostKey = true,
                HostName = _configurationRepository.FtpServer,
                UserName = _configurationRepository.FtpLogin,
                Password = _configurationRepository.FtpPassword,
            };
result.AddRawSettings("SFTPMaxVersion", _configurationRepository.FtpSftpMaxProcolVersion);

new TransferOptions()
            {
                TransferMode = TransferMode.Binary,
                OverwriteMode = OverwriteMode.Overwrite,
                PreserveTimestamp = false,                
            };
result.ResumeSupport.State = TransferResumeSupportState.Off;


We are deleting every file before Put it on the remote server.
* RemoveFiles function is reporting it is succed
* PutFiles function is reporting error 11.

Here you have a complete session. We have the same problem with files with no special characters, ie: ATT00001.txt

Adding a bit more info:

On RemoveFiles Winscp function....
RemovalOperationResult is reporting IsSuccess to true

But there are no items in
* RemovalOperationResult.Removals
nor
* RemovalOperationResult.Failures.

Re: RemoveFiles/PutFiles

The argument of Session.RemoveFiles is a wildcard.
https://winscp.net/eng/docs/library_session_removefiles
https://winscp.net/eng/docs/library_wildcard

The [1] in the filename is a set pattern. No file in the remote folder matches that pattern, hence nothing is removed.

As documented, you should escape the filenames using RemotePath.EscapeFileMask to avoid them being interpreted as wildcard/file mask.
