Hi @Leandro Figueira ,
You could achieve this using powershell. Please refer to this article: How to Upload File to SharePoint Library using PowerShell?
Add-PSSnapin Microsoft.SharePoint.PowerShell -ErrorAction SilentlyContinue
#Function to Upload File
Function Upload-File($WebURL, $DocLibName, $FilePath)
{
#Get the Web & Lists to upload the file
$Web = Get-SPWeb $WebURL
$List = $Web.GetFolder($DocLibName)
#Get the Files collection
$Files = $List.Files
#Get File Name from Path
$FileName = $FilePath.Substring($FilePath.LastIndexOf("\")+1)
#Delete the File from library, if already exist!
If($Files.Item($DocLibName +"/" + $FileName))
{
$Files.delete($DocLibName +"/" + $FileName)
}
#Get the File
$File= Get-ChildItem $FilePath
#Add File to the collection
$Files.Add($DocLibName +"/" + $FileName,$File.OpenRead(),$false)
#Dispose the objects
$web.Dispose()
}
#call the upload function
Upload-File "http://sharepoint.company.com" "Monthly Reports" "D:\Reports\LargeLists.txt"
