A mature WordPress site contains PO, MO, POT, and JSON files under plugins, themes, the global languages directory, and an old deployment tree. Nobody knows which catalogs are current, which are generated, or which custom translations will disappear during the next update.<\/p>\n

Treat the scan as an ownership exercise, not a deletion list. Connect every maintained source to its generated output, runtime location, component release, and update owner. Files that cannot be explained should remain untouched until their role is proven.<\/p>\n

    What it means<\/h2>\n

    Language-file management covers the inventory, ownership, validation, compilation, placement, and lifecycle of WordPress translation catalogs. POT files describe translatable source messages, PO files contain editable translations, MO files serve compiled PHP gettext messages, and generated JSON files can supply translations to JavaScript.<\/p>\n

    A scan identifies candidate files and metadata. It does not show by itself which catalog WordPress loads, whether a duplicate is safe to remove, or whether an update will replace a custom file.<\/p>\n

    A realistic WordPress example<\/h2>\n

    A multilingual site has two German MO files for the same plugin: one inside the plugin directory and one in the global WordPress languages directory. An older deployment folder contains a third copy with the same filename. Only one serves current requests, but the timestamps alone do not reveal which one.<\/p>\n

    The administrator maps each file to its component version, text domain, locale, source PO, deployment destination, and update owner. The dormant deployment copy is excluded from the active inventory, while the two reachable catalogs are tested to establish their loading order before either is moved.<\/p>\n

    Why it matters and when to use it<\/h2>\n

    Scan after installing, updating, translating, or migrating a component, when troubleshooting inconsistent translations, and before any language-file cleanup. A reliable inventory prevents custom work from being mistaken for generated output and exposes files that will be overwritten by the next release.<\/p>\n

    The goal is not the smallest possible language directory. It is a clear, update-safe chain from authoritative source to runtime artifact, with proof that each required locale works in the contexts where visitors and administrators use it.<\/p>\n

    A straightforward route for beginners<\/h2>\n
      \n
    1. Back up custom PO sources and their MO or JSON outputs before renaming, compiling, moving, or deleting anything.<\/li>\n
    2. Inventory the file type, locale, text domain, component, version, full path, timestamp, size, hash, and owner.<\/li>\n
    3. Classify each item as vendor-managed, a WordPress language pack, maintained custom source, generated output, duplicate, or unknown.<\/li>\n
    4. Connect every MO or JSON artifact to the PO, POT, or source revision that produced it.<\/li>\n
    5. Compare maintained catalogs with the current component source to find new, obsolete, fuzzy, contextual, and plural messages.<\/li>\n
    6. Quarantine unknown files for review instead of deleting them from the scan results.<\/li>\n<\/ol>\n

      The advanced route<\/h2>\n

      Present the inventory as a source-to-runtime matrix. One row should connect a component release, locale, domain, source or POT revision, maintained PO file, generated MO or JSON file, deployment path, update owner, and last successful runtime test.<\/p>\n
