I'm trying to use UDiff to deploy changed files from one site to another. I'm having trouble getting UDiff to put the following files and directories into the output directory:

App_Data\access.config
App_Data\packages\

Here is the UDiff command I am executing:

MoriyamaUDiff -o C:\udiff_files -umbracosource C:\inetpub\LiveSite -project C:\inetpub\StagingSite -c -u
goto :eof

I haven't found any other files missing. Just the two I listed above. I originally had a big exclude statement and suspected a problem in one of my regex expressions, but the example above excluded the -exclude statement and still resulted in missing files.

It is also important to note that this problem only shows up when the -umbracosource directory is empty when I do the udiff. In other words, if access.config existed in -umbracosource, udiff will report changes to this file in the output directory, but when -umbracosource has no access.config, UDiff will not report that access.config is new in the output directory.

Is this a bug? Am I doing something wrong?

Thanks!
