Make sense of your old drives.
Drive Helper helps you see what is in ordinary folders, find files with the same contents and bring a chosen collection together. It works on your computer. Your files stay local, and you review the plan before copying.
Free to use. No account or upload needed. Choose Try an example first inside the helper to explore with small, made-up files.
What you can do
- See what is here. Choose folders from one or more drives and give each collection a name you recognise.
- Check matching contents. The helper reads the files all the way through. Matching names alone do not count as duplicates.
- Review the new collection. Keep the folder layout or group recognisable collections. Choose which matching copies to include. All are included at first.
- Create a checked copy. Choose a destination, approve the plan and let the helper copy and read back every saved file. A browsing index and report go into the new folder.
Your original files stay where they are. Leaving a matching file out of the new collection does not remove it from its source.
Before you start
Begin with a small, readable folder of documents, photos, videos or music. Keep the tab open until copying and checking finish. Make sure the chosen destination has enough room.
Saving directly to a folder needs a supporting desktop browser, such as recent Chrome, Edge or Opera. The helper checks what is available. Other browsers may offer scanning and downloadable reports.
App libraries, system folders, selected project packages and known disk-backup images are skipped and listed. This first version does not recover deleted files, repair damaged drives or open Windows backup images.
Copied files may show today's date. Original modification dates are recorded in the report; computer permissions, Finder tags and other extra file information are not preserved. Empty folders are not included. Keep existing backups and app libraries in their original form.
If a copy stops, COPY STATUS.txt in its new folder says INCOMPLETE. Keep your originals and read the report. This version starts a fresh folder when you try again.
Take it with you
