31. older The quick scan utility performs at a similar speed to Windows Explorer when set to find out the size of a directory The detailed report that is produced at the end of a quick scan is intended to be an indication of space Savings that can be achieved The estimated reductions are based on average reduction achieved on thousands of files tested The Quick Scan utility can be used while NXPowerLite for File Servers is running without conflict To save time we recommend using this utility prior to running NXPowerLite for File Servers in Evaluation Mode Evaluation mode Prior to registration NXPowerLite will be locked in Evaluation mode and in this mode you will be able to point NXPowerLite at your server folders and produce a report of the estimated space savings In this mode NXPowerLite copies each file in turn to create a temporary file and then optimizes it It then 2 NXPowerLite for File Servers Help ME NXPowerLite for File Servers Help deletes the temporary file taking note of the difference between the size of the original and optimized versions of the file When it has finished processing all of the candidate files NXPowerLite generates a report detailing the total expected space savings Our default settings suffice for most cases but while evaluating you may want to see the effect of various settings on the expected space reclaimed Q ae Please note In Evaluation mode the original file is never modified delet
