space in folder name

0

Hello! We have a problem with FTP component. Consider this ftp site structure:

root
-> Dir with space
   -> file with space.txt
...

When using Ftp.GetList() recursively, we will never see the file in its results.

On the other hand standard windows ftp client (as well as win explorer) can reach the file without any problems.

Could you please point me to a solution or fix this bug.

Version of Rebex.Net.Ftp.dll is 3.0.3793.0 I've also tried 3.0.3854.0 with the same result

Thanks in advance.

Igor.

Below is some output from different tools

Conversation continued over the email. I'm posting the summary here so it can help others in similar situation.

The original code look like this:

ftp.GetList(\""Dir with space\"")

and it returned the empty list.

The Windows command line client was able to list the directory content using the ls "Dir with space" command, but was unable to list the content using the dir "Dir with space" command.

The ls "Dir with space" in fact issues following FTP command sequence 

NLST Dir with space

and dir "Dir with space" issues following FTP command sequence

LIST Dir with space

This specific FTP server supports listing directories with space in name as a parameter to NLST command, but does not support the same for the LIST command.

Workaround 1

Use the parameterless variant of GetList. It will return the full info about files (such as file sizes). It will use the LIST FTP command.

ftp.ChangeDirectory("\"Dir with space\"");
FtpList items = ftp.GetList();
ftp.ChangeDirectory("..");

Workaround 2

Use the NLST command. It will return only filenames with no additional info.

string[] items = ftp.GetNameList("Dir with space");

For more info on LIST and NLST command see question FTP and LIST/NLST commands

Solution

Update/reconfigure the FTP server so it can handle spaces in directory names in the LIST command.

Have you tried passing the quotes (") character to GetList? Such as

client.GetList("\"Dir with space\"") // in C#

  • or -

    client.GetList("""Dir with space""") 'in VB.NET

?

The format of FTP protocol's LIST command arguments is not defined, so we don't do this ourselves.

Unfortunately this easy solution does not work for concrete ftp server. Rebex ftp console client (one of samples delivered with the product) does not see the folder as well.

Could you update the your question and include the log output and error message from situation when client.GetList(""dir with space"") syntax is used? Or mail it to support@rebex.net for analysis?

Sure. It'll be in your mailbox shortly
