Reclaiming Space (Default behaviour)
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.
Watched Folders (Requires configuration)
By default, NXPowerLite will replace files with smaller versions and without configuring 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.
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.
NXPowerLite can be installed on any of the following Windows operating systems with .NET v4.5.2 installed:
Windows Server 2008 R2
Windows Server 2012
Windows Server 2012 R2
Windows Server 2016
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.
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.
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.

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..
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...
NXPowerLite's file compression is a lossy one-way process so it is important to ensure that there is a record of how the file has been compressed. NXPowerLite inserts a very small amount of metadata into each successfully compressed file which means next time any NXPowerLite product comes across it they can skip it safely. We call this metadata a 'Tag'.
Files will be shared with others and moved within file systems and inserting a Tag into the file means that it does not get lost and travels with the file. Adding a Tag does increase the size of the file very slightly but the total size of the Tag data is less than 100 bytes. Read more
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.
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)
Microsoft Excel 2007-2016 Open XML format (.xlsx, .xlsm, .xltx, .xltm)
PDF documents (.pdf)
JPEG images (.jpeg, .jpg, .jpe, .jfif, .jif, .jfi)
TIFF files (.tiff, .tif)
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.
Offline Files is a feature of Sync Center (Windows Feature) that makes network files available to a user, even if the network connection to the server is unavailable. Users can use offline files (if enabled) to make their network files always available offline to keep a copy of the files stored on the network on your computer. This allows users to work with them even when they are not connected to the network or a server is unavailable. The next time the user connects to the network or the server is available, their offline files on your computer will automatically sync to the network files on the server to update.
NXPowerLite skips these files because the compression process makes fundamental changes to the file and could cause issues with the syncing process. Once files are marked as online (by the user connecting to the network) then the files will be compressed by NXPowerLite.
You should be able to see where these files reside by reviewing the logs files located here:
