Office365 SharePoint - Rename Multiple Files in Document Library

Unfortunately, Office 365 SharePoint doesn't let you to do too much using the built-in PowerShell cmdlets. Sometimes this trick can also come in handy with On Premise SharePoint installations when you just need a quick way to manipulate files in a library. Using PowerShell commands this is much more complicated.
Last day I ran into an issue (maybe I'll post that later) when I had to rename multiple files in a Document Library that resides on an Office 365 SharePoint instance.

What I did was the following:

Step1 - Add the website to the IE's Trusted Sites

First of all, you have to use Internet Explorer. Open in Explorer mode only works with this browser. Add the website to the trusted site's list then restart the browser. Otherwise it will complain later.

Now browse to your SharePoint Library again.

Step 2 - Open the Library in Explorer

Go to Library -> Open with Explorer

Step 3 - Map the location as a Network Drive

Now that you can see the library in Explorer, you need to grab the URL from the Address bar (ctrl + c) and map a network drive:

Press the ALT + T -> Map Network Drive

Choose a drive letter, paste your path and Finish. You may not want to reconnect the drive at logon.

Now, that you can see your files as a drive you can use your favorite tool to manipulate them.

Step 4 - Use your favorite tool to manipulate the files

I just used cmd to rename all pdf files but you can do much, much more with Total Commander if you have to.

Of course, this method work with SharePoint Server (On Premise) as well.

Renewing JIRA's the SSL Certificate on Windows

Basically this is JAVA specific stuff.


  • Windows Server 2008 R2
  • JIRA Standalone (6.2) (Installed in C:\JIRA)
  • JDK 1.7 (Installed to C:\JDK)
AFAIK this method applies to all JIRA and JAVA/JDK editions.

Step 1: Identifying the JKS (Java KeyStore) file location

This is the file where the certificates used by Tomcat are stored. The JKS file is linked with JIRA in the server.xml file that is located under the JIRA INSTALL DIRECTORY\conf\server.xml (In this example C:\JIRA\conf\server.xml). Open in notepad and search for JKS to find the section we're insterested in. 

SSLEnabled="true" acceptCount="100" clientAuth="false" connectionTimeout="20000" disableUploadTimeout="true" enableLookups="false" keyAlias="tomcat" keystoreFile="C:\JIRA\cert\jira.jks" keystorePass="somepass" keystoreType="JKS" maxHttpHeaderSize="8192" maxSpareThreads="75" maxThreads="150" minSpareThreads="25" port="443" protocol="org.apache.coyote.http11.Http11Protocol" scheme="https" secure="true" sslProtocol="TLS" useBodyEncodingForURI="true" />

Step 2: Creating a CSR

For this you use keytool.exe that is located in your JDK instance's bin directory. You will be asked for the keystore password that can also be found on the xml mentioned earlier. Make sure to mention the -alias parameter with the keyAlias attribute from the settings.xml file.

C:\JDK\bin> keytool -certreq -keystore "C:\JIRA\cert\jira.jks" -alias tomcat

No questions asked, the request will use the same properties as your current certificate. Now copy-paste the CSR from the console and send it to your CA that will issue the certificate for you.

Step 3: Installing the new certificate

Once you got the new certificate save it as a .cer file (I'll save it as C:\JIRA\cert\jira.cer in this example) and open its properties to export *all* the CA certificates from the certification path:

Click on View Certificate -> Details -> Copy to File and export it in the DER encoded binary X.509 format.

After the exports, in this example I'll have 3 certificates to import into the KeyStore file:
jira.cer (the certificate I got from the CA)
ca-root.cer (the first certificate exported in the Certification Path)
ca-intermediary.cer (the second certificate exported in the Certification Path)

So go back to the Command Prompt, you JAVA instance's bin directory and use keytool.exe to import all these certificates. When you're asked if you want to import the certificate, type yes at the console.

C:\JDK\bin>keytool.exe -importcert -keystore "C:\JIRA\cert\jira.jks" -storepass somepass -trustcacerts -alias ca-root -file "C:\JIRA\cert\ca-root.cer" C:\JDK\bin>keytool.exe -importcert -keystore "C:\JIRA\cert\jira.jks" -storepass somepass -trustcacerts -alias ca-intermediate -file "C:\JIRA\cert\ca-intermediate.cer" C:\JDK\bin>keytool.exe -importcert -keystore "C:\JIRA\cert\jira.jks" -storepass somepass -trustcacerts -alias tomcat -file "C:\JIRA\cert\jira.cer"

Restart Tomcat (JIRA) and you're done.

Top FREE Cloud Storage Providers - 2014

Short and on subject (as always :).

Did some research on the market and currently these are the top Cloud Storage Providers that offer the Most Free Space and have Desktop and Mobile (iOS, Android) Sync Clients.
Everyone is starting the list with Dropbox but that's outdated offering a shameful of 2GB.

  1. - 50 GB
  2. FireDrive - 50 GB
  3. - 20 GB (Sync up to 3 devices)
  4. - 15 GB (Or you get 20GB if you register from this referral)
  5. Google Drive - 15 GB
  6. - 15 GB
  7. - 10 GB
  8. - 10 GB (250 MB max file size)
  9. Microsoft OneDrive - 7 GB

Note - I personally recommend, it's a great service. Works almost just like Dropbox but you get a ton of space. You get an additional 5GB for every referred friend.

Although you can scrape up a bunch of free space this way I don't recommend installing more than two sync clients on your computer because it can seriously affect the computers performance.

I will update this list as soon as something interesting comes up.

VBoxManage modifyhd Code CO_E_SERVER_EXEC_FAILURE (0x80080005) - Server execution failed

This is a lol one. I tried extending the hard disk of a Virtual Machine and received the following error:

C:\Program Files\Oracle\VirtualBox>VBoxManage.exe modifyhd "E:\Virtual Machines\JIRA\Windows Server 2008.vdi" --resize 40960
VBoxManage.exe: error: Failed to create the VirtualBox object!
VBoxManage.exe: error: Code CO_E_SERVER_EXEC_FAILURE (0x80080005) - Server execution failed (extended info not available)
VBoxManage.exe: error: Most likely, the VirtualBox COM server is not running or failed to start.

The Solution

Do *not* start Command Prompt as admin!
