File System Analyzer
PoINT File System Analyzer is a free software tool that is used to determine the amount of inactive data on a data storage system. The tool is easy to use, provides an intuitive user interface, and scans user-specified file systems. The results are a dynamic analysis of the amount of data that has not been accessed by users and applications for a specific time period.
Unlike other data storage analyzer tools, PoINT File System Analyzer is a small 325k executable file that does not require installation on a host system, and runs non-intrusively against any CIFS or NFS file system.
