Revit creates a bit of a mess sometimes, leaving behind backup and journal files that can take up disk space and clog your system. I have posted about a few cleanup tools before, including:

You may also have heard about MoveBackup. This tool was created by Maxence Delannoy and has now been renamed to Wormhole for Revit. It comes as a 30 day trial and it can move your Revit backup files to a directory that you choose.

You can download the Revit 2016 – 2018 version here and the 2015 version here.

Support for Revit 2015 has been dropped. So if you’re still using this version of Revit, please download the 0.4 here :

There is a nasty little bug that sometimes causes Backups (and any attempted Restore) to fail on a workshared project.  The way to avoid this problem is so simple that it should probably be implemented on all workshared projects in your office:

check Regenerate if view/sheet is not up-to-date.  This will create a thumbnail for the non-opened view to be included with the initial backup version and eliminate the error message when saving the backup version.

However – if you have already come across this problem and it is too late to check the above box … you may be able to get the Restore to work IF you reinstate an appropriately named preview.xxxx.dat file into the _backup folder.  Its worth a try if you are struggling to recover some important data.

I had to format and re-install Vista on a laptop over the holiday break. Given that it was an OEM version, and the original disks were not available, I was faced with a bit of a conundrum. How will I restore the activation data without having to contact Microsoft?

Perhaps you have faced a similar problem. Often, OEM installation media is packed with software you don’t need, and it only serves to slow down your PC right from the get-go. However, you can install Vista using standard installation media, and then ‘backup and restore’ the Vista activation data. This way, you are starting with a truly ‘clean’ system. Of course, you will then need to download and install all the necessary drivers for your system.

Before starting the process, I backed up the activation data using the software at the link below. After obtaining some installation media, I installed Vista without providing any product keys (you should be able to do this with any retail Vista media). Then, I restored the activation data. It worked perfectly.
