Supported Files and Limits¶
This page lists the file types TrialMind accepts and the limits that apply when you create a protocol and when you add to its Source Files.
File types¶
| File type | Supported for upload |
|---|---|
| Yes | |
| DOCX | Yes |
| PPTX | Yes |
| XLSX | Yes |
| CSV | Yes |
| TXT | Yes |
| MD | Yes |
| DOC, PPT, XLS | No. Save the file as DOCX, PPTX, or XLSX and upload it again. |
| Macro-enabled Office files (DOCM, PPTM, XLSM) | No. Save a copy without macros. |
| Images (JPG, PNG, and others) | No |
| ZIP archives | No |
| Other file types | No |
The same types apply in the New Protocol wizard and in Source Files.
TrialMind decides a file's type from its extension and then checks that the contents match. A file that is renamed to a different extension is refused.
Files TrialMind refuses¶
Even a supported type is refused if:
- A PDF is password-protected.
- A PDF, DOCX, PPTX, or XLSX file is corrupt or cannot be read.
- An Office file contains macros.
- An Office file is built in a way that expands to an unsafe size.
The row for the file shows the reason. Remove the password or macros, or save a clean copy, and upload it again.
Limits¶
| Limit | Value | Applies to |
|---|---|---|
| Documents when creating a protocol | 1 to 20 | The New Protocol wizard |
| File size | 50 MB per file | The wizard and Source Files |
| Files in a protocol | 50, including the documents uploaded at creation | Source Files |
| Notes in a protocol | 200 | Source Files |
| Note title | 200 characters | Source Files |
| Note text | 50,000 characters | Source Files |
| File name after renaming | 255 characters | Source Files |
The 20-document limit applies only while you create a protocol. After creation you can add files until the protocol reaches 50 files, counting the original documents. Notes are counted separately.
What you can see in a preview¶
| File | Source Files preview |
|---|---|
| Shown inline | |
| Notes, TXT, MD, CSV | Shown as text. Text longer than about 256 KB is shortened. |
| DOCX, PPTX, XLSX | Not previewed. Download the original to open it. |
What happens to a file after it is added¶
| Where you add it | What TrialMind does |
|---|---|
| New Protocol wizard | Reads the file as part of extraction and proposes protocol details. |
| Source Files, after the protocol exists | Stores the file and can use it as AI context. It does not start a new extraction. |
