If you have more than 5 files to send, its easiest if you compress all of your files into zipped files.
- Locate the file(s) or folder that you want to compress.
- Right-click the file(s) or folder, point to Send To, and then click Compressed (zipped) Folder.
A new compressed folder is created. To rename it, right-click the folder, click Rename, and then type the new name.
If you aren’t sure if your files have been uploaded, check the section where you added the files and a confirmation will show next to each file name as the image here:
