Duplicate files in the HubSpot file manager

Migrations, imports and repeated uploads often leave the same file in the HubSpot file manager several times under different names or folders. The copies make it unclear which version is current and add volume to every migration. Find files with identical content, pick the copy to keep, and remove the rest only after checking what links to them.

Why it matters

When the same PDF exists five times, teams link different copies in emails, pages and records. Updating one leaves the others out of date, and customers may receive the old version.

Duplicate files add volume to every migration and backup, and make it harder to confirm that the files you meant to move actually arrived.

How to find it in HubSpot

  1. Open the file manager, usually under Marketing or Content, depending on your portal.
  2. Sort files by name and size and look for matches with similar names in different folders.
  3. Pay attention to folders created by imports or migrations, which often hold copies.
  4. For each likely duplicate, check where it is used before deciding anything.

How to fix it safely

  1. Choose the canonical copy for each group, ideally the one already used on live pages and emails.
  2. Update pages, emails, templates and records that point at the other copies.
  3. Keep any copy that a record or note still depends on until its links are moved.
  4. Delete redundant copies only after migration checks pass and the file owner approves.

Before you change anything: Deleting a file breaks every link to it, including links in emails already sent. Check usage carefully and keep anything you are unsure about.

How Ancil checks this

Rule
MIGRATION-001
What it looks for
Reads up to 2,000 files from the file manager and groups them by the content hash HubSpot stores for each file. Flags groups where two or more files share the same hash, which means identical content. It only runs when at least 2 files are read.
Severity
Info.
Evidence shown
The number of files read, plus up to 25 duplicate groups, each with the hash and the ID, name, path and size of each file.
Governed fix
Not automated. Ancil reports the evidence only. Your team, or an INSIDEA expert, removes copies. Ancil does not delete or move files.
