Member paths inside the .fz are the relative paths you pack: from a folder (best — full tree), or for loose file(s) the archive uses each file’s name at the root (e.g. products_export_1.csv). Choose a folder, choose file(s), or drop a folder / files below. Several top-level folders at once work best in Chromium (directory entries). Web demo: upload size cap in the footer; huge trees need the CLI.
After upload, building the .fz on the server can take several minutes for PDFs and other large files (you will see a timer and status line). This is expected, not a hang.

Fractal_zip is still running. For large PDFs or big trees this often takes several minutes — the bar cannot show inner steps, but work continues until a download link appears below.
