This window exposes options relating to advanced product usage scenarios.


File System Analysis Thread Pool


Specifies the number of threads available for file system analysis work.


In-Memory File Tracking


When this option is enabled, FolderSizes will track file data in system memory. This increases the granularity of folder reports (including those created from snapshots) and eliminates the need for additional file system access when browsing through report contents. However, a small amount of memory will be allocated for each file encountered during the scan - increasing memory usage and (modestly) decreasing performance.


If this option is disabled, FolderSizes will initially store only folder-level system data in memory. File data will be fetched from the file system as needed to support folder report drill-down operations. This mode allows FolderSizes to create folder reports for extremely large file systems faster, and with less memory usage.


We recommend disabling this feature when creating folder reports for file systems containing a very large number of files or where report generation performance is a priority.
