SNAPSHOT COMPARISON
FolderSizes can compare any two file system snapshots and show you exactly what's changed between them - folders and files added, deleted, or modified, along with the metadata behind every change. It's the fastest way to answer the question: what's different?
Built for Investigative Workflows
Pick a source and target snapshot, and FolderSizes builds a merged folder tree that highlights every change at a glance. State indicators - added, deleted, modified, and unchanged - are color-coded throughout, so you can scan the tree and immediately see where the activity is concentrated.
- Compare any two snapshots, even across different machines or time periods
- Drill into changed subtrees with a single click
- Hover any folder for a rich side-by-side comparison of its metadata and aggregates
- Filter the view by state to focus on exactly what matters
Detail Where You Need It
The detail report shows side-by-side source and target values for size, modification time, attributes, owner, link target, and creation/access timestamps. A colored "State" pill on each row makes it instantly clear whether an item was added, deleted, modified, or unchanged - and a signed size-delta column quantifies every change in a single glance.
Practical Applications
- Auditing - what changed on a file server between two points in time?
- Compliance - demonstrate before/after state for major system changes
- Forensics - investigate unexpected file system activity within an incident window
- Capacity planning - quantify growth and turnover between baselines
- Troubleshooting - identify exactly which files or folders changed during a deployment
Comparison results can be exported to CSV, HTML, XML, or plain text for distribution to stakeholders who need answers but don't need direct access to the source systems.
