Alternative to flow upload - Verify that the uploades Files are vaild

Hello Guys,

i just updated my NC from V23 to 25.0.4.

At the old Version i used the File Upload Manager “Flow upload” to load my files up.
With this Upload-Manager it was possible to see, if an File wasn´t correctly uploaded.

With the NC25 the App “Flow upload” is not longer supported.
So if i see it correctly, than i have no chance, to verify the uploaded files with the original file on my HDD.
Or is there a possibility to see it?
