charge the full folder the first time and after update only the last files

[Anonymous]

Hello,

I have a robot which gives data in a txt file inside a folder.

After a size of txt files (17579 Ko), the robot create a new file with incrementation.

When i open PowerBI, i want that the whole folder is include.

But it is very long. As if PowerBI update the whole folder and forget that it has already charge a lot of data of the last update. For example i open PowerBi in March and it charges the whole files in blue (see picture). But when i open PowerBI two weeks after, it charges again the blue files and the red files.

Do you have an easy example ? Because i really do not understand what i read on the internet...

Thanks and sorry for my poor english 😉
