I use the keep remote directory up to date function a lot. When I recently got the error that my directory tree had grown over the maximum of 62 folders, I was back here quickly to see about an update and indeed, it was waiting for me :)
So 3.72 -> 3.74 and on I went, or not.. Somehow it doesn't quite do what it promises anymore: it forgets to upload updated files at times, alas.
Pinpointing.. not too much info here, I'm afraid :(
:arrow: WinSCP 3.74
:arrow: SFTP (v3)
:arrow: Norton Commander style interface
:arrow: Steps: Keep remote directory up to date on a tree of about 100 folders, sync options: delete, update, no confirmations. Then start, minimize. I do have one more copy of WinSCP active at same time, watching another tree.
:arrow: Errors: none, but a lack of action
The only thing I could think of is that it is perhaps much slower in watching / checking with larger trees. That seems to be an unlikely cause though, as 3.72 with about 50 folders to keep up to date responded within a second or two and 3.74 with about 100 hasn't done so yet after more than a minute.
