That is not right. After the import all categories were empty. All KeePass folders have been copied. In addition, there is a folder "import", in which all data were additionally available. So the data is duplicated. (Picture 1) If I now move a record from the folder "import" to Logins, the record still remains in the folder structure (Picture 2) Since I am not 100% sure whether actually all records are double, I must compare every time.
What I can do: Hide the categories and delete the "Import" folder. I am not sure if all data is deleted.
Would not be nice, since I have already spent some time in the processing of the data
