Filesender is a service that allows sharing large files (up to 500GB files in HTML5-supporting browsers) with up to 100 recipients at once.

Web interface: https://filesender.cesnet.cz

  • To use the service, you need to log in with your faculty account (via CAS).
  • You can upload only one file at a time. It is recommended to compress multiple files into one archive file (zip, rar, etc.).
  • You cannot send files with the *.exe extension; they must be renamed or compressed.
  • The maximum storage time is 30 days.
  • You can provide a “one-time invitation” (called a voucher) for external collaborators – the voucher recipient can send files using the service without logging in.
