Upload hard cap
Absolute max size of one file. When a tier's max upload size is 0 (unlimited), this ceiling applies. Default 5 GB.
Upload hard cap
Maximum size of one uploaded file in GB. Applies to desktop, remote URL, copy, SFTP, and API uploads.
Where to find it
Admin → Settings → Mods → Upload sources → Upload hard cap
Setting key: upload_hard_cap_gb
Default 5 GB (typical range 1-1024).
How it works
- Per-tier max upload MB (Users limits) applies when set above zero
- Tier max
0means "unlimited at the tier" → the file still cannot exceed this hard cap - Positive tier limits are also bounded by the hard cap
Common problems
Premium unlimited still capped at 5 GB
Raise upload_hard_cap_gb - tier 0 is not infinite.
Nginx 413 before the app sees the file
Raise Nginx client_max_body_size too (Nginx and HTTPS). Package defaults are often in the same ballpark as 5 GiB.
