How it works
- Pick your folderGrant access to the folder containing the files you want to rename. Disk Tamer reads your local file system directly in the browser — nothing is uploaded.
- Configure your rename rulesChoose from find-and-replace, prefix/suffix insertion, counter addition, date stamping, or extension change. Combine multiple rules in sequence.
- Preview every changeSee a side-by-side list of every old → new filename before anything is touched. Spot collisions or mistakes before they happen.
- Run and review resultsClick Run. Disk Tamer renames each file and shows you a result summary with any errors flagged.
Common use cases
- Rename 500 camera photos from IMG_XXXX.jpg to 2024-03-15_001.jpg format
- Strip a prefix added by an export tool: client_report_Q1.csv → Q1.csv across 40 files
- Add a version suffix to all .txt files: notes.txt → notes_v2.txt
- Change all .jpeg extensions to .jpg in a folder of mixed images
Frequently asked questions
- Does Disk Tamer rename files on my computer or upload them somewhere?
- Your files never leave your machine. Disk Tamer uses the browser's File System Access API to rename files locally. Nothing is uploaded or sent to a server.
- What rename operations does Disk Tamer support?
- Find & replace in filename, add prefix, add suffix, insert counter, insert today's date, change extension, and combinations of these in sequence.
- Can I undo a bulk rename?
- There is no automatic undo. Always review the preview list carefully before running. If you need to reverse a rename, set up the inverse operation and run it again.
- What happens if two files would end up with the same name after renaming?
- Disk Tamer detects collisions and warns you before running. The Run button stays disabled until all conflicts are resolved.
- Does it rename folders or only files?
- Currently Disk Tamer renames files. Folder renaming is not yet supported.
- Which browsers does Disk Tamer work in?
- Disk Tamer requires a browser that supports the File System Access API — Chrome 86+, Edge 86+, and Opera 72+. Firefox and Safari are not currently supported.
- Is there a file count limit?
- There is no hard limit. Performance depends on your machine — thousands of files work fine.
- Can I use a CSV to control rename targets?
- For CSV-driven workflows, use the Bulk File Create feature which supports full CSV templates. The rename operation uses pattern rules applied to all selected files.
