This article explains how files are stored and referenced in Drive, and how to configure which file types your team can upload.
Permanent CDN URL
Every file you upload to Drive gets a permanent CDN URL in the following format:
https://cdn.document360.io/[project-id]/Images/Documentation/[filename]
This URL is what your articles reference when they display an image or link to a file. Understanding how each Drive action affects this URL is critical before you move, copy, replace, or delete files. The table below summarizes the impact of each action.
| Action | What it does | Effect on CDN URL | Risk |
|---|---|---|---|
| Move | Relocates a file to a different folder | URL unchanged. Linked articles stay intact | Low |
| Copy | Duplicates a file to a destination folder | New URL assigned to the copy | Low |
| Replace | Overwrites file content with a new file of the same type | URL unchanged. Articles are updated within 20 minutes | Irreversible (Old content cannot be restored) |
| Remove | Deletes the file and moves it to the Recycle bin | URL becomes invalid. All linked articles break | High (Check dependencies before removing) |
| Download | Saves file(s) to your local storage as a .zip file | No effect | None |
| Add tags/alt text | Adds metadata to the file for search and accessibility | No effect | None |
Before you act on a file
Always check a file's dependency count before making changes. The Dependencies column in Drive shows how many articles, homepage sections, or content reuse elements reference that file. If the count is greater than zero, removing or replacing the file will affect live content.
To check dependencies: navigate to Drive, locate the file, and select the number in the Dependencies column. The File dependencies panel lists every article and content element that references the file.
Drive settings
Navigate to Settings > Knowledge base portal > General > Drive settings.
Allowed file types
By default, Allow all media formats is selected, permitting any file type. To restrict uploads to specific formats:
- Select Choose allowed media formats and click Add.
- Enter the Media type in the format media type/extension (for example, image/png).
- Enter the Extension in lowercase (for example, .png, .svg, .jpg). This field is case-sensitive.
- Click + to add the format, then click Save.
- File names must not contain the characters +, %, #, or =.
- Owners and Admins can control which file types are permitted for upload.
