The hands you upload live in Files & Database, in the Tracker's left list under DATA. This is the page where you confirm a file arrived, check how much of it FlopHero analyzed, and remove the files you no longer need.
It has two views, switched at the top right: Files and Database. It opens on Files.
Files: every upload, one row each
Each uploaded file is one row. File and Site identify it, Imported says when it arrived, and Status says whether it has finished processing.
Two counts sit side by side. Hands is everything in the file; GTO Analysis is how many of them FlopHero analyzed, with the share as a percentage. When those two differ, Why Some Hands Aren't Analyzed explains the gap. The row under the list totals both counts across all your files.
A drop strip above the list takes more files: drop them onto it, or click choose files.
Remove a file
To remove a file, click the cross at the end of its row. There is no undo, so read the row before you click. If you need the file back, Uploading Hand Histories covers putting it in again.
If the file is still in the list after you refresh the page, you did nothing wrong. Rather than removing it again, send the file name to support.
Database: where the hands live
The Database view shows the database your hands go into. Your first one is called Default. It shows how many hands it holds, when it was created and when you last imported into it, and carries Rename, Clear hands and Delete. New database creates another one.
Keep your list current
The list does not refresh itself after an upload lands. The refresh icon at the top right of the view reloads it.
