SharePoint 2013 Service Pack 1 appears to delete the contents of wpresources

Question

I downloaded SP 1 Mark 2 for both Foundation and Server on 2 different farms.

In both cases, the contents of C:\Program Files\Common Files\microsoft shared\Web Server Extensions\wpresources were deleted. I have some 3rd party products that deploy files here.

I don't have anti-virus installed. The folders aren't in the recycle bin. The folders were NOT missing immediately after the service pack deployment. It happened some time over the course of 3-4 days.

Is this expected? Can anybody explain what's happening here?

I installed the binaries on my 1 web server and ran psconfig.exe -cmd upgrade -inplace b2b -wait and it went through successfully. I've done this many times. I don't think it was a matter of me installing the service pack incorrectly.

Answer 1

wpresources is meant to hold all of the supporting resources for installed web parts. It could be images, additional code, forms, help files, etc.

I don't think, this is SP1 issue, as you mentioned...You install it and run the config wizard via psconfig tool and no issue reported.

Did you run the Config Wizard via GUI after that?

What install in the wpresources folder, may someone uninstall the solution or something?

Also check the ULS / Event Log or more clue.
