and I forgot to say it is recognized OK and also shows 32 GB and I have 50 files on it named like: autobackup_5.0.30_365days_(2022-02-03_00-00-00_1643842800232) But no possibility to save the other...

@Hank21 I was out for some weeks. Sorry for that. The format is FAT32 and the size 32GB

Yes indeed.

Hi, I use the Ookla speedtest app in the Microsoft Store.

@Somnus Nope that is also not it.. What you mention is what I already do for a long time. See my attached file. The other history (there are 2 settings) etc will all go into the controller and no way...

@Somnus I tested it and all saved history goes to the Primary Controller storage and NOT to the attached USB stick. So my featire request stays valid.
