WinSCP v5.11.1 on Windows 2012 Server R2 Standard

We have seen that keepuptodate (FTP) does not work when (we think) the number of folders is too high.
We have a folder C:\foo which contains 150'000 subfolders
It contains a folder C:\foo\bar which contains 65'000 subfolders

When we use keepuptodate on the C:\foo folder it does not detect new files (we waited several minutes). If we watch C:\foo\bar it does (quite quickly) notice new files and changes etc.

Is there some limitation to how many folders it can watch?

The depth of files is 4 i.e C:\foo\bar\three\four\file.jpg

There's no limitation as such.
But I can imagine that Windows suppresses the notifications, when there are so many.

In my test scenario there would not have been "many" notifications as I only changed one file. WinSCP did not notice it however.

However we now see that WinSCO did not notice some changes on the smaller subfolder as well so it seems to be really unreliable. Sad

Thanks for your report.
I have sent you an email with a debug version of WinSCP to the address you have used to register on this forum.

A new connection for each "ls" command? Check out FileZilla and you will see:

Code:
Status:   Resolving address of ecom-app01.buhlergroup.com
Status:   Connecting to 194.9.121.212:21...
Status:   Connection established, waiting for welcome message...

Status:   Retrieving directory listing of "/foo/bar/import"...

My question however is if there is way of lessening the log so we only see relevant information like what is being written.[/code]

While FileZilla does not display the connection in the message log in GUI, that does not mean it does not connect.
What you have posted is not a log file anyway. Enable real logging in FileZilla and you will see that it does connect too.
