Duplicate file names

In the desktop app, when you upload a file with the same name as an already saved row or sheet, you’ll have to select one of these options:

  • Attach as a new version of the original file
  • Attach as a separate file with a duplicate name

Alternatively, consider changing the name before you upload.

On the mobile app, you can upload identically named files will be uploaded directly without the option to save as a new version. 

Attach files with the mobile app

Explore the Smartsheet App for iOS or the Smartsheet App for Android if you’re looking for information about using your mobile device to attach multiple files and edit images.

Attach files with Brandfolder

You can attach files directly from your Brandfolder account to your sheet. When you attach an asset from Brandfolder, you link the row or sheet to the asset in Brandfolder, and you can make changes to the asset.

You can change file details, replace and update the asset, and more. The asset you access through Smartsheet will always be the latest version.

When you select Attach from Brandfolder, the Brandfolder panel opens.

  2. Choose the files you want to upload from Brandfolder.
    To attach multiple assets, use the checkboxes.
