https://prosody.im/doc/modules/mod_http_file_share reads ----------------------------- Retention Files are stored for a week by default, matching the default retention period of mod_mam. To change this set the http_file_share_expires_after to the desired retention period. Component "upload.example.org" "http_file_share" http_file_share_expires_after = "31 days" In Prosody 0.12.x this setting is a number in seconds. Setting to "never" disables expiry of uploaded files. ----------------------------------- Please remove "matching the default retention period of mod_mam" because that easily suggests as if the module uses that setting if not set explicitly. It shredded quite some uploads unintentionally of this misunderstanding with me. Put line Setting to "never" disables expiry of uploaded files. BEFORE the line about the 0.12.x as it is not applicable to 0.12.x ! While using Prosody 0.12.3 and likely all 0.12+ versions, setting http_file_share_expires_after = "never" or http_file_share_expires_after = 0 do NOT work. Also, using Conversejs as front-end, its paperclip vanishes. Present version 0.13x DOES support the "never" setting. The mod_http_file_share.lua source of version 0.12 does not parse "never" and 0 means "no retention at all". For version 0.12.3 (= present version for Raspberry Pi B+ on Debian Bookworm), setting expiry to "never" requires http_file_share_expires_after = <big number like 9999999999 seconds> http_file_share_expires_after = math.huge or http_file_share_expires_after = -1 Please include those settings for the 0.12 versions.

http_file_share_expires_after = math.huge won't work. It assigns (nil) to the expiry variable and throws an error due to expiry >= 0 according to the module's source.
