FileLever helps you compare folders, find exact duplicates, and review storage-heavy files across local folders, external drives, Dropbox, and locally synced Google Drive folders. Preview the result first, decide what stays or changes, and then sync, delete, move, or archive with more confidence.

Common file problems
Managing files should not feel risky
Synced folders slowly fall out of sync. Duplicate copies consume storage. Large files become difficult to find, and deleting files in bulk can feel unsafe when you cannot clearly review what will happen. FileLever helps you inspect the problem first, select the right files, and take action only when you are ready.
Out of sync folders
Duplicate file build-up
Cleanup anxiety
Bulk file actions
Storage creep
Duplicate files waste storage
Duplicate photos, documents, downloads, and backups can be difficult to review across locations.
Review load
Large files are hard to find
Old videos, archives, installers, and forgotten project files can consume significant space while remaining buried across folders.
Cleanup risk
Bulk cleanup feels dangerous
Bulk deletion feels risky without a clear view of what stays and what gets removed.
Use Cases
Built for the file cleanup tasks people usually postpone

How FileLever Works
Review first. Act only when you are ready.
Move from folder selection to review and action with one clear workflow for comparing folders, cleaning up duplicates, and reclaiming storage across local folders, external drives, direct Dropbox locations, and locally synced Google Drive folders.
1
Choose what you want to review
Select local folders, a direct Dropbox location, or folders synced locally by another desktop client.
2
Review the results
See folder differences, duplicate groups, or files sorted by size from one clear interface.
3
Select the right files
Choose files individually, select multiple results, or use safe bulk-selection controls.
4
Take action
Sync folders, remove duplicate copies, delete unnecessary files, or move large files to an archive after explicit confirmation.
FileLever Tools
Solve common file and storage problems from one desktop app
Folder Sync
Keep folders and backups up to date.
Compare a source and target folder, review new or changed files, and then run a copy/update sync. Use mirror mode only when you intentionally want target-only files removed.
Duplicate File Finder
Find duplicate files and recover wasted storage.
Scan folders for exact duplicate files, review matching groups, choose the copy you want to keep, and delete the others selectively or in bulk.
Large File Reviewer
Find what is consuming your disk space.
View files sorted by size, inspect large or forgotten files, and then delete them or move them to another folder for archival.
Safe File Review
Stay in control before files change.
Review full paths, file sizes, proposed actions, and selected files before running a sync or cleanup operation.

Powerful and safe cleanup features
File operations can be difficult to reverse. FileLever keeps results visible and actions deliberate so you remain in control of every folder sync, duplicate cleanup, and storage review.
Private by Default
