Your files are automatically checked in two stages when they are added to the Files tool on web. Files have to pass the first upload check to move to the process for viewing check.
| Stage | What's Checked | Common Reasons for Failure | What Happens If Failed | What Happens If Successful |
|---|---|---|---|---|
| Upload | Files are checked for: - File type support - Network connectivity - Server availability |
- Unsupported file type - No network connection - Server issues |
Files can't be added to the Files tool. Click Retry to try again if network or server issues are resolved. |
Files appear in their folders and can be managed using file actions. However, files can't be viewed until they pass the Process for viewing stage. |
| Process for viewing | Files are checked to ensure they can be opened in the viewer. | - Password protected files - PDFs exceeding 2,000 pages - Files over 5 TB - Corrupted files |
Files can't be: - Viewed in the viewer - Compared - Published to sheets - Marked up - Exported Workaround: PDFs can be viewed using Open in browser or shared for download. |
Files can be used and viewed normally. |
The Process for Viewing action is used specifically for files that have passed the upload stage but haven’t yet been processed into a web‑viewable format (for example, for viewing in the viewer, thumbnails). This includes files uploaded using Desktop Connector.
Most files uploaded using Desktop Connector do not process for viewing automatically. This allows the files to upload and sync quicker to web where you can process files on demand.
THe following files will process for viewing automatically when uploaded using Desktop Connector:
