If it is necessary to attach any large files to the proposal, such as estimates, drawings or projects, then:

• first, upload the file to an FTP server;

• then, link the relevant system form from the corresponding FTP server site where the file was saved.

Open the upload software (in our example we will be using free software WinSCP).

Connect to the FTP server by indicating the required data:

• File protocol – FTP;

• Encryption – TLS/SSL Explicit encryption;

• enter the host name;

• make sure that port 21 is selected;

• enter your EPS e-tender subsystem username and password;

• click on the button Login.

The connection window opens. After a successful connecting process, the left side of the open window will show your computer's folder and file system, and the right side will show the FTP server environment.

Perform the upload transaction.

• Click on the button on the left and select the folder where the documents are located that need to uploaded. The files in the selected folder are displayed in a list on the left.

• On the right, find the folder named and double-click on its name.

• On the left, mark the files for upload and click on the button.

• In the popup window click on the button.

You can also upload a file by dragging it click on the file and without relesing the left mouse button drag the file to the FTP server side; then release the left mouse button and the file will be uploaded.

After a successful uploading process, the files are saved in the folder specified by the FTP server.

Once the files have been uploaded to the FTP server, they can be attached to the proposal.
