Component Setup

Adding to a Record Page

1. Open any record page in Lightning App Builder.
2. Find Smarter Files in the component palette.
3. Drag it onto the desired region of the page layout.
4. Save and activate the page.

Component Properties

The following properties are available in the Lightning App Builder sidebar:

Property	Description	Default
Card Title	Component header text	Files
Storage Mode	Standard — files linked via ContentDocumentLink (visible in Files related list). Isolated — files linked via junction record only (hidden from Files related list, enables visibility controls).	Standard
Display Mode	How files are displayed: List (vertical rows) or Tiles (grid of cards)	List
Default Sort Order	Initial sort order for the file list. Users can change at runtime. Options: date-newest, date-oldest, size-largest, size-smallest, name-az, name-za	date-newest
Initial Files Displayed	Maximum number of files shown initially. Set to 0 to show all files. A “Show All” link appears when there are more files.	5
Allowed File Extensions	Comma-separated whitelist of extensions (e.g., pdf,docx,png). Only these types can be uploaded. Leave empty to allow all types.	All types
Excluded File Extensions	Comma-separated blacklist of extensions (e.g., exe,bat,sh). These types are blocked from upload.	None
Max File Size (MB)	Maximum file size for uploads in megabytes. Set to 0 for no limit.	0 (no limit)

Upload Restriction Logic

When both Allowed and Excluded file extensions are configured, they work together:

1. Allowed list is checked first — if a file’s extension is not on the allowed list, it is blocked.
2. Excluded list is checked second — if the file passed the allowed check but its extension is on the excluded list, it is still blocked.

In other words, a file must be on the allowed list and not on the excluded list to be accepted.

Tip

In most cases, you only need one of the two settings. Use Allowed when you want to restrict uploads to a small set of known types (e.g., pdf,docx,xlsx). Use Excluded when you want to block specific types but allow everything else (e.g., exe,bat).

Placement Tips

• Works in the main content area, sidebar, or full-width regions.
• Can be placed on any standard or custom object record page.
• Multiple instances on the same page are supported (e.g., different configurations per tab).
