SpaceSniffer is a freeWare (donations are welcome) and portable tool application that lets you understand how folders and files are structured on your disks.
SaaSHub's Down Detector checks the status of services automatically and regularly. However, we cannot promise 100% accuracy. That is why we depend on user reported issues as well. The DiskUsage status here can help you determine if there is a global outage and DiskUsage is down for everyone or it is just you that is experiencing problems. Please always report any issues to help others know the current status.
