How to send big files

How it works

GrosFichiers is a free service for businesses and individuals to send at once up to 4 GB files to one or several recipients through a web browser such as Internet Explorer, Firefox, or Safari.

GrosFichiers acts as intermediary between the sender and recipients. Each recipient receive by email a link to download the files, which are stored on our servers until then.


Step by step


Step 1: Select your files

  • Click on the red link "Select your files" --> a window opens to select files
  • Select one or more files (multiple selection by holding down the CTRL key, or CMD key on Mac)
  • Validate your selection --> the window closes and the files appear in step 1 section
  • Delete a file by clicking on the red tab next to it or delete all files with the red tab in the summary box
  • Select and validate files as many times as needed

Step 2: Upload your files

  • When at least one file appear in step 1 section, you can start uploading your files
  • Click on the red link "Start uploading your files" --> the files transfer begins
  • Interrupt the transfer if necessary by clicking on the red "Stop uploading" tab
  • Repeat steps 1 and 2 as often as necessary
  • During files transfer, you can already move to Step 3

Step 3: Write your email message

  • Write your message at any time (take advantage of the uploading time)
  • Fill in the "Your Name" field --> displayed as "Sender" to recipients
  • Fill in the "Your email address" field --> important! Confirmation email will be sent to this address
  • Fill in the "Email recipients" field --> used to provide the recipients with the link to download your files
      automatic formatting of addresses copied/pasted from an email service contacts' list
      add up to ".RECIP_MAX." recipients (fields open one by one)
  • Fill in the "Subject of the email" and "Content" fields
  • Fields marked with an asterisk (*) are mandatory and must contain valid information in order to send the email
  • To avoid waiting for files transfer completion, you can choose the automatic sending option under step 4

Step 4: Send your message and files

  • Click on the red tab "Send your email and your files" --> the Confirmation page gets loaded
  • If files transfer is still ongoing, you can use the option "Click here to send automatically when uploading is complete" (but be careful not to close the website window!)
