I have been shooting inspection and documentation footage since 2016, and in 2023 I found a 2018 folder labeled “Johnson house” that contained 340 files with names like IMG_4823.JPG and MVI_0044.MOV. The address was not in the folder name. The date was not in the file names. The EXIF metadata had accurate timestamps but no GPS. I knew the client’s name; I did not know which of the three Johnson properties I had shot that year this was. That folder represented two hours of work and a complete loss of the documentation function it was supposed to serve. I spent a morning reconstructing the file from email and my calendar. I have not named a file IMG_anything since.
The naming convention that survives a decade
A documentation file needs to be findable by address, date, and content type — ten years after it was created, by someone who was not the creator. My current naming standard:
[Street-Address]_[YYYY-MM-DD]_[session-type]_[sequence].ext
Example: 1847-Meridian-Ave_2024-03-14_PRE-cleaning_001.jpg
Address first, so folder sorting puts all files from the same property together. Date in YYYY-MM-DD second, so files sort chronologically within an address. Session type — PRE, POST, PROGRESS-wk04, PUNCH-LIST, FINAL — tells the story without opening the file. Sequence number distinguishes files within a session. Elements separated by underscores, never spaces, because spaces break some file systems. This convention looks bureaucratic. It is. It is also why I can find any file from any property I have documented in under 30 seconds, on any machine, without opening a database.
Folder structure for multi-session property files
Each property gets a top-level folder named for the street address. Inside: one subfolder per session, named by date and session type. Inside each session: the files named as above. Adding category subfolders — Stills, Video, RAW, Processed — is unnecessary; the file name already carries that information. One exception: if a property has footage from two separate contractor relationships, add year subfolders inside the address folder to prevent two jobs merging into one list.
Backup strategy: the rule of three
One copy is not a backup; it is a single point of failure. The minimum for property footage with legal or insurance relevance is three copies: one working copy on your main machine, one on a local external drive kept offline, one off-site. The National Archives recommends a 3-2-1 structure for any digital records intended for long-term preservation: three copies, two media types, one off-site. That standard applies directly to property documentation files that may need to be produced years after capture.
The practical implementation: working copy on the main drive, encrypted external drive in a separate location, and cloud backup through a service that stores files in original format without transcoding. Transcoding can degrade quality and strip metadata. Verify your cloud service preserves video in original format before trusting it for documentation files.
Metadata preservation across backups and file transfers
EXIF metadata is generally preserved across copy operations but can be stripped by social media uploads, some editing software, or format conversions. When moving files between drives, I use a verified copy tool that checks source and destination hashes. I do not modify metadata after capture — if a timestamp needs a correction, I add a text note to the session folder. Video is kept in original camera format (.MP4 or .MOV); any compressed delivery copy is labeled separately as a copy.
Retrieval: finding a file when someone else needs it
I maintain one index spreadsheet per year: one row per session with the address, date, session type, file count, drive location, and a one-line note. Two minutes per session to update; lives at the root of the documentation drive. Anyone with access can navigate without knowing the folder structure. For a related workflow on before-and-after file organization with repeatable camera positions, see recording repointing on a Philadelphia row house: matching mortar on camera.
Frequently asked questions
How should I name property documentation photos so I can find them years later? Lead with the street address in a consistent format, followed by the date in YYYY-MM-DD format, a session descriptor, and a sequence number. Use underscores rather than spaces. The file name should tell you what the photo is, where it was taken, and when — without opening it. Apply this convention consistently from the first file in a session, not retroactively.
How long should I keep property documentation footage? Keep footage for the full duration of any applicable warranty, plus at least the statute of limitations for construction defect claims in your state — which ranges from three to ten years depending on jurisdiction. For documentation used in an insurance claim, keep it until any appeal period has expired and the claim is fully closed. For a property you own, keep the documentation until the property sells and then transfer it to the buyer.
What is the minimum backup setup for property documentation files? Three copies: one on your working drive, one on a local external drive kept in a separate physical location, and one on a remote cloud service that stores files in original format without transcoding. Verify the backup by doing a test restore of a random file at least once per year. A backup that has never been tested for retrieval is not a backup; it is a hope.
