SCCM 2012 SP1 - Evil Folders in Reporting Services - What Are They and How to Remove Them

Hello All,
There are a lot of sub-folders in the http://CentralSiteSCCM/ReportServer. They are like:
<dir> Config_Mgr_CEN
<dir> Config_Mgr_CEN.OLD.0
<dir> Config_Mgr_CEN.OLD.1
<dir> Config_Mgr_CEN.OLD.10
<dir> Config_Mgr_CEN.OLD.100
<dir> Config_Mgr_CEN.OLD.1000
Only <dir> Config_Mgr_CEN is properly populated with the correct set of the default folders.
Would you be so kind to advise on:
What are they?
How to remove them?
What to do in order for them not to appear any more?
Thank you very much in advance!

Hi Mike,
I ran into an issue when I did the SP1 upgrade where a majority of our reports were duplicated. I created a script to delete these duplicate reports and I've adjusted it to work for your situation. You can find the original thread here, if you're interested:
http://social.technet.microsoft.com/Forums/en-US/configmanagergeneral/thread/dc9aa3b4-cea9-4a07-87ca-2795a2dbc04e
You'll need to know your SCCM site code and the server name to run this script.
# SCCM2012SP1-RemoveDuplicateSSRSFolders.ps1
# This script will connect to SSRS on a specified server and delete all folders that end with .OLD.*
# Used for SSRS cleanup after SCCM 2012 SP1 installation
# Script must be run from an account that has access to modify the SSRS instance

ForEach ( $folder in $foldersToDelete ) { $ssrs.DeleteItem($folder.Path) ; $deletedFolderCount++ }
Write-Host "Folders have been deleted. Total number of deleted folders:" $deletedFolderCount
Standard disclaimer: While this script worked just fine for me in my environment, I make no guarantees that it will work anywhere else. I've attempted to make this script as user friendly and generic as possible, but it may require slight tweaking to work properly.

What are the "bookmarkTools.dupBm160" (many entries) in about:config and how can they be removed if not needed?

In about:config I noted MANY entries that start with: bookmarkTools.dupBm
What are they? What purpose do they serve? How to get rid of them if they serve no purpose?

Probably added by an extension.

I am freeing up some space and am using osx lion, but i have 12gb of back ups, how can i delete these and what are they?

Gotcha.
Back-ups are what they are: a safety copy. If you feel you don't need them, you can trash them. They could be of a previous System if you upgraded, or something else. You wont get the full picture from looking at system profiler.
You may want to look into getting an external drive and offloading some stuff to it.

My ipad mini has many emails which say 'no content' and are not deletable. What are they are how do I delete them?

My ipad mini has many emails which say they have no content and I cannot delete them. The emails do not show up on my MacBook Air. What are they and how do I get rid of them?

Close the mail app and reset the iPad. Closing apps instructions are for iOS 7. If you're not running iOS 7, I assume that you know how to close apps in iOS 5 or 6. If you don't know how to close apps, just reset the iPad.
To close an app, drag the app up from the multitasking display. Double tap the home button and you will see apps lined up going left to right across the screen. Swipe to get to the app that you want to close and then swipe "up" on the app preview thumbnail to close it.
Reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up.

Effect
Sends a message. Messages are stored in table T100, and can be maintained using Transaction SE91. They are fully integrated in the forward navigation of the ABAP Workbench.
The ABAP runtime environment handles messages according to the message type specified in the MESSAGE statement and the context in which the message is sent. There are six kinds of message type:
A (Abend)
Termination
E (Error)
Error
I (Info)
Information
S (Status)
Status message
W (Warning)
Warning
X (Exit)
Termination with short dump
Messages are used primarily to handle user input on screens. The following table shows how each message type behaves in different contexts. The numbers are explained at the end of the table.

I have a long list of gibberish files, in Preferences, in my Library. What are they? How did they get there? Can I delete them?

Here is one thing I found googling for WebEx:
http://www.webex.com/why-webex/overview.html
(The x64 would most likely mean 64 bit). It may be a Windows based application/plugin, but since I had never heard of either, I'm only guessing there. If you do a search systemwide for it and don't find it plus don't know why it's there, I'd say throw it in the trash (don't empty it yet - make a note of the file path just in case you do have something installed that needs it so you can move it back).
Glad to hear it's not a torrent; some people use those not realizing that quite often there is a price to pay for downloading stuff for free that costs money elsewhere - the software packages quite often include little "add-ons" = malware which you really don't want.

What are these and what are they useful for?: and

I have seen these symbols being used in Java: << and >>, what are they and what do they do?
Thank you.

As DrQuincy asks how is this of use over multiplying
and dividing?In your processor there are often different instructions for shifting, multiplying, and deleteing. Typically the shifting instructions take less time to execute and so using the shifting operator will be faster than multiplying. This assumes the compiler doesn't recognize the situation and optimize it out though.
The >>,<<,>>>, &,|,and ^ operators are mainly useful when you need to deal with individual bits of data. For instance if you are talking to another system (thats not java) that uses a different method of storing numbers (little endian/big endian etc.), or doing something such as creating parity data for error correction. There are lots of things to do, but most a low level and its rare when you need to use them.

I found some little black dots n my iPhone 5 screen. I've only had it for 2 weeks. What are they and will apple replace my iPhone for a new one or fix it?

They should have one in Stock, but you never know. Call your Apple Store and tell them you have an iPhone 5 color and GB, and that you most likely will need a replacement, do they have any in Stock. If yes, go in, if not ask for advice on how to handle your problem.

Some of my songs and TV shows have a circle with a square in it next to them and are darken and I cannot listen to or watch these items. What's going on and how do I fix it?

Try resetting you phone by holding the power and home buttons at the same time until you see the Apple logo, then release. If no change you might need to try syncing all your music and TV shows off your iPhone, then sync them back on (be sure they are in your iTunes library before doing so).

E-mails with attachments, mostly photos, are replicating themselves in my inbox, 100 or more at a time. What is causing this and how do I fix it?

It is an intermittent, but a regular-enough-to-be-really-annoying occurrence........when someone sends an e-mail, to which is attached a photo of some kind, or a picture document, it will replicate in my inbox, sometimes 100 or more copies at a time. I delete all of them, empty the trash, and will also go to the Yahoo web version of my e-mail and delete the offending e-mail from there and empty the trash. Sometimes worked. Now that process isn't working, and this particular e-mail just filled up my inbox with over 100 copies of itself, even after the other steps were taken. Can't get any incoming mail.
This log jam of replicated e-mails prevents incoming and new mail from reaching the inbox.
Needless to say, am not too happy about it. What is causing it, and how do I fix it, other than to go to Outlook for my e-mail client....? :0) This, coupled with the constant "not responding" each time I try to send an e-mail, delete items from the "sent" or inbox folders, is really driving me nuts. We have a crappy internet connection, and that is likely part of it, but the "not responding" is not a new thing with Thunderbird, either.
Thanks in advance for any assistance you can provide. I dislike the web version of Yahoo, and don't want to have to switch to that, as it just doesn't meet e-mail needs. Would like to get Thunderbird fixed.

I have not seen your error in either my IE or my chrome. I do note that you are using a "strict" Document Type Declaration.
You might try a transitional DTD, which should be more forgiving than the strict:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
Other than that, I don't see anything particular (because I don't see the error, either) that would cause the menu to drop vertically instead of horizontally.

I have an iMac (the desktop) I've stupidly left the cable you plug the monitor into the wall with there. What are they called and where can I get a new one?

Presumably the mains cable, which you can get from an Apple Store.

Just updated to iOS8 and most of my music disappeared. Attempted to sync with iTunes to get it back but iTunes now says I am 26GB over capacity and "Other" files are taking up just over 29GB! What is going on and how do I fix this?

iPhone 5 (64GB)
iTunes 11.4.0.18 (64-bit Win7)
Just updated my iPhone 5 to iOS8 and most of my music disappeared. Attempted to sync with iTunes to get it back but iTunes now says I am 26GB over capacity and "Other" files are taking up just over 29GB! What is going on and how do I fix this?

I had restored my iPhone 5 to factory settings and that cleared the problematic "Other" problem. Flash forward a couple weeks and the problem has once again resurfaced.
I tried updating iTunes and iOS to the newest versions and the problem still persists.
I'm officially ready to switch to Windows Phone or Android now...
*edit*
A Google search with results restricted to the last month shows that this problem seems to be becoming more and more common.

Yosemite 10.10.2 server app. FTP help. I have a program running in my local server enviroment that wants to FTP to my mac folder. It asks for the server , name, password, port and path. what are they?

So I have set up a localhost area in my Mac. I have the new server.app and I am running yosemite 10.10.2 .
I have a program running in my local server enviroment that wants to FTP to my mac .
It asks for the server , name, password, port and path. what are they?
I am pretty certain that the Serveris "localhost",
Name is my macs name (like my-mac-min)
password is "my login password"
and they suggest port 21.
But what is the file path, lets just say my site is set up http://localhost/siteftp and is actually at my Users/Sites/siteftp folder.
Why cant this program connect to the mac.
Is it because they are both operating in the same localhost enviroment,
could it be my folder permissions are not correct on siteftp folder?
Help please !

I tried turning the computer off and then back on. The alerts don't show the notice to update as resolved. Hopefully this is not a problem or an indicator or another problem. Should I ignore or reload 10.10.1 from the app store to trigger a resolved check in a green circle?
Interesting that I had to buy server software after my free Yosemite download. I would have hoped that the two pieces of software would have gone together without any complication. It is not positive to end up buying a problem. Ah well, time to move on.

What are environment variables and how are they employed?
