# File Upload Details

CLOAD file upload feature supports large file segmentation, ensuring that files are stably and securely stored on the blockchain. Below are the detailed steps and important considerations for file uploads:

***

### **1.File Upload Steps**

\
**Open the Upload Window:**\
In the file upload pop-up, you can add files by:

* Dragging and dropping files into the upload window.
* Clicking the **Browse Files** button to select files from your device.

**Check Cycles Consumption:**\
In the lower-left corner of the window, you’ll see the number of Cycles required to upload the file.\
Make sure you have sufficient Cycles; otherwise, the file cannot be successfully uploaded.

**Confirm Upload:**\
Click the **Confirm Upload** button to start the upload process immediately.

### **2.Upload Process Explanation**

\
**Segmentation:**\
To ensure stability and security, the platform splits the file into 1MB segments.\
Each segment is encrypted and tagged, ensuring file integrity and security during transmission.

**Distributed Storage:**\
After segmentation, file chunks are distributed to multiple nodes.\
This approach enhances storage stability and reduces the risk of a single point of failure.

**Upload Time:**\
Upload time depends on the file size and network stability.\
Please be patient and keep the upload window open until the process completes.

### **3.Important Notes**

\
**Ensure Network Stability:**\
Maintain a stable network connection during upload to avoid upload failures due to unstable connectivity.

**Sufficient Cycles Balance:**\
If your Cycles balance is insufficient, the upload cannot be completed. Check and top up in advance.

**Failure Handling:**\
If the upload fails due to network issues or node errors, the file segments become invalid.\
You will need to restart the upload process to ensure file integrity.
