See attached image. I clicked on + sign left to folder name. And after 30 minutes it is still in this state (as on attached image). Also I invoked 'Download from here' from this dir context menu. Downloading started after 6 minutes and still not finished.

[06.05.10 20:53] Download from (brock)
[06.05.10 20:59] Download file '/dkadADdaodADo/vspfiles/templates/104/104/Install.txt' to 'D:\Work\brock\new_issues\work\vspfiles\templates\104\104\Install.txt'

Total dir '104' size is about 5 MB. Remote FTP server is Microsoft FTP Service and it breaks connection after ~30 seconds (or even less) idle time.

We have to look at deployment logs. Steps are same as at http://youtrack.jetbrains.net/issue/WI-1553#comment=27-145440 except the category name is 'com.jetbrains.plugins.webDeployment.ftp'.
Thank you!

I found log.xml. But where is ~/Library/Caches/WebIde10/log/idea.log on my Win7 PC? Can you give more clear instructions?

I have attached log of opening templates\104\104\ folder (see attached screenshot). What I can see in the log that PhpStorm for some reason reads file list of templates\104\104\ child folders. I will attach of downloading this folder when it will be finished :(.

What I see from your logs (open_templates), WebIDE issues separate MDTM command to determine the accurate last modified time for every file.

Why it does MDTM at all? See https://issues.apache.org/jira/browse/VFS-257

Attached log of folder downloading. How can I turn off this MDTM command?

Starting from the next build you will have an option (Settings | Deployment | choose your server | Advanced Options):

Always: call MDTM for every file shown in Remote Host view
On copy: call MDTM to check if file is up to date (if 'Overwrite up-to-date files' is off) and when file is downloaded (to preserve it's timestamp)
Never
