This is the UTC hour for events in that file (hours are numbered 0 to 23).\n - `20160225_234912` is in `YYYYMMDD_HHMMSS` format. This is the time the report was generated in local account time (DCM and unified) or EST (DBM only).\n - `218211994` is the file ID.\n\nHow do I know when all files are delivered?\n: For each day there are: \n\n - 24 click files (hours 0-23).\n - 24 impression files (hours 0-23).\n - 1 activity file.\n - 21 match tables.\n\n Clients with custom configurations may have different numbers.\n\nWhat if I encounter duplicate files for the same date and hour?\n: This can happen. When more than one file has the same date/hour stamp, use the one with the\n latest minutes / seconds, based on the filename timestamp.\n\nI think some of my data is incorrect, what can I do?\n: Contact your support representative with information about the problem. If data\n seems to be missing, provide details about which hours are missing, and files that aren't\n accounted for.\n\nHow do I find out what's been deprecated in v2, or moved to match tables?\n: See the [migration guide](../migrating) for information on mapping from v1 to v2."]]
