I do that first, but it's appear that the download take 1000 times longer. I don't know why.

For the moment I try with the FileMask and if I catch an error, I'll loop on each file.
Or I'll make a smaller list

Thanks for your answer,
Sincerely.

OK, so it's about file mask. I understand now.

You should better call Session.GetFiles for every file individually.

The error can be shown on line 2107 in alaloop-synch-manager-session.txt

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

Hi everybody!

I used WinSCP 5.7.0.5125 With WinSCPnet.dll.

When I used the Session.GetFiles function with a short list file all works fine. But when I give as parameter a long list (more than 500 Files) I catch an Exception when I called TransfertOperationResult.Check just after the GetFiles.

'_oResult.Check()' threw an exception of type 'WinSCP.SessionRemoteException'
base {WinSCP.SessionException}: {WinSCP.SessionRemoteException: Missing parameter for command 'get'. à WinSCP.OperationResultBase.Check()}

If I call Session.GetFiles one by one (for each file) all works.
The only difference between the first and the second call is that i have defined the FileMask of TransfertOptions.
I've tried this because it seems that downloading files one by one takes more time than TransfertOptions.

so : my questions are :
- This exception is it normalous ?
- Did they have a limit of files for GetFiles ?

Eric
