What happens if the file uploaded to COS FTP Server exceeds the maximum limit?

If a file uploaded to a COS FTP Server exceeds the maximum limit, the upload will typically fail. This is because the server is configured to accept files only up to a certain size, and exceeding this limit violates the server's settings.

For example, if the maximum file size limit on the COS FTP Server is set to 100MB, attempting to upload a 150MB file will result in an error. The exact error message may vary depending on the server configuration, but it will generally indicate that the file size exceeds the allowed limit.

To handle such scenarios, you can:

1. Compress the File: Before uploading, compress the file to reduce its size below the limit.
2. Split the File: Split the large file into smaller parts that are within the size limit and then upload them separately.
3. Increase the Limit: If you have control over the server configuration, you can increase the maximum file size limit. However, this may require additional server resources and should be done cautiously.

In the context of cloud storage, services like Tencent Cloud offer scalable solutions that can accommodate large files. For instance, Tencent Cloud's COS (Cloud Object Storage) allows you to store and retrieve any amount of data at any time from anywhere in the world. It provides flexible storage classes and lifecycle management to optimize costs and performance based on your needs.
