About this tool
Catch duplicate file names before import, upload, or archive steps so asset lists stay clean and do not overwrite each other in shared systems.
This page is designed to handle one clearly defined job with less friction than a spreadsheet, editor, or heavier app. The best utility pages feel obvious, focused, and immediately reusable.
- Counts duplicate file names from a simple line-by-line list.
- Can match duplicates with or without letter-case sensitivity.
- Useful for CMS imports, image exports, and shared-drive cleanup.
How to use Duplicate File Checker
Enter the input in the panel above, review the output, and copy or export the result once it matches the task you need to finish. If the workflow continues, use the related tools below as the next step.
When this tool is useful
- Scan upload manifests for duplicate names before importing files into a CMS or DAM.
- Check shared-folder exports before handing assets to another team.
- Review migration spreadsheets where duplicate names could overwrite files downstream.
Practical tips
- Run a case-insensitive pass first because many storage systems treat upper and lower case as the same path.
- Pair duplicate checks with file-name cleaning if assets came from multiple naming conventions.
- Review duplicate groups before removing anything because different folders can still contain intentionally reused names.
Why people use this tool
