FAQs: NXPowerLite for File Servers (includes Watched Folders)

Reclaiming Space (Default behaviour)

How does it work?
NXPowerLite works by replacing original documents and images with smaller versions in each of your configured folders which will reclaim space. It has two integral parts: A Windows service in the background to process the files and a Dashboard to configure how and what folders or drives are processed.
How fast does NXPowerLite process data?
On average, NXPowerLite will process around 1TB of data in a 24-hour period. There are many factors that will affect the performance and more details on this are available in the support article:  Performance tips: Configure NXPowerLite for File Servers for speed.

 

Watched Folders (Requires configuration)

How does Watched folders work?
By default, NXPowerLite will replace files with smaller versions. However, it will not watch configured folders and compress any new files that arrive. However, it possible to configure it to rescan the configured folders every minute. That way it will effectively reduce any file that arrives in the folder within one minute. To configure it in this way please see Manually configure NXPowerLite for Watched Folders for a detailed explanation.
When configured for Watched Folders can NXPowerLite save compressed files to another folder?
The simple answer to this is no. NXPowerLite is unable to save the compressed file to another folder, it will simply replace the original file with a smaller, compressed version. It is also possible to use NXPowerLite SDK to build this feature into your custom workflow, including saving to another folder.

Can I optimize content on non-windows devices?
Yes. While NXPowerLite needs to be installed on a Windows Operating System, it can optimize content on any network device in the Windows domain. It has been used successfully with every SAN and NAS device that we have seen so far.
How does NXPowerLite interact with background scanning software e.g Anti-virus or Backup scanners?

By its nature, NXPowerLite will change a lot of files, especially in its initial pass-through of the data. This means that it will start a lot of activity with any active scanning software such as anti-virus or backup. This will improve over time as the number of changes to files reduces.

How is NXPowerLite compression different to Deduplication or Compression?
NXPowerLite does not remove duplicate files or compress files. It works on pre-compressed files like user documents and images that typically don't respond as well to deduplication or compression. It looks for 'waste' within those files, which it strips out completely. This leaves you with smaller source files, which should then amplify the effect of your deduplication.

Features

Can I reduce files on mapped drives or UNC paths?
Yes. If you cannot add a folder or drive with the simple folder browser, it is possible to enter any UNC path using our Add Multiple folders... feature. Here you can enter multiple paths to the content you want to optimize. Read more...
Is it possible to schedule the NXPowerLite?
Yes. There is a highly configurable in-built scheduling feature, or it is possible to use task manager to pause or resume the NXPowerLite. Read more...

 

File Processing

What happens to the last modified/accessed dates of files when they are processed?
NXPowerLite works hard to ensure that files look like they remain untouched. After processing, files will have the same Last access and last modified date, along with all the metadata that the original file contained.
What file formats does NXPowerLite work with?
NXPowerLite can optimize the following types of files with the following extensions:

Microsoft PowerPoint 97-2003 binary format (.ppt, .pot, .pps)
Microsoft PowerPoint 2007-2016 Open XML format (.pptx, .pptm, .potx, .potm, .ppsx, .ppsm)
Microsoft Word 97-2003 binary format (.doc, .dot)
Microsoft Word 2007 - 2016 Open XML format (.docx, .docm, .dotx, .dotm)
Microsoft Excel 97-2003 binary format (.xls, .xlt)

PDF documents (.pdf)
JPEG images (.jpeg, .jpg, .jpe, .jfif, .jif, .jfi)
TIFF files (.tiff, .tif)
What happens to files that have been through an OCR process?
NXPowerLite should work seamlessly with files that have been through an OCR process. NXPowerLite does not change any of the font data so there is little chance of it interfering with OCR process.
