File Naming Conventions That Still Make Sense in Ten Years

A file name is the first piece of metadata every file receives, and in many family archives it is the only one. A thoughtful naming pattern means that someone opening your folders a decade from now, perhaps a relative or perhaps you after a long break, can understand what each file is without opening it. Good conventions are not fancy. They are plain, consistent and written for a reader who was not there.

Name for a Stranger

Imagine that the person looking at your files has no memory of the events. Would 'IMG_4821.jpg' tell them anything? Would 'Scan final.pdf'? A name written for a stranger includes the who, what and when in just a few words. If a name needs your memory to make sense, it will fail you eventually.

Lead With the Date

Placing dates at the beginning, in the order year, month, day, lets files sort in time order automatically. A name such as 2019-08-17 begins a chain that stays in sequence no matter which program lists it. Use two digits for month and day, so that 09 comes before 10. When you only know the year or month, write only that part, for example 1998 or 1998-07, rather than inventing a day.

Add a Short Description

Follow the date with a few plain words about the content. Aim for a description that you would search for. Examples include family-reunion-lakehouse, passport-renewal-scans or grandmothers-recipe-cards. Avoid abbreviations only you understand. If you must use one, record its meaning in a short note in the folder.

Pick Safe Characters

Some systems and web services handle certain characters poorly. To keep your files portable for the long term:

• Use letters, numbers, hyphens and underscores.
• Avoid slashes, colons, question marks, asterisks and quotation marks.
• Be cautious with accented letters and symbols, since different systems may display them differently.
• Avoid leading or trailing spaces, and consider replacing spaces with hyphens.

Keep Names a Sensible Length

Very long names are hard to read and can run into path length limits on some systems. Choose a length that fits comfortably on one line in a file list. If the folder structure already provides context, the file name does not need to repeat it.

Use Sequence Numbers Carefully

When a set of files belongs together, such as scanned pages, add a number with leading zeros: 01, 02, 03 and so on. With enough zeros to cover your largest expected count, files stay in order. Without them, 10 may appear before 2.

Handle Versions Honestly

If a document has drafts, label them v1, v2 and so on, or add the date of the draft. Reserve the word 'final' for a copy you have truly closed. Many archivists keep only the final and the first versions of working documents, deleting intermediate drafts unless they have some value.

Write the Rules Down

A convention is only useful if it is remembered. Put a short text file in the top folder of your archive explaining the pattern in a few lines, for example: date first, then topic, then description, all lowercase with hyphens. A future reader will be grateful, and so will you.

Apply It Gradually

You do not need to rename thousands of old files at once. Start with new additions, then rename older files as you touch them. For large groups, such as camera photos, a bulk rename tool can add a date prefix automatically. Before using one on irreplaceable files, test it on copies.

Beyond the Name

A file name can only carry so much information. For richer details, such as people, places and notes, use the metadata fields built into many formats, or a simple catalog. Names and metadata work best together, and each makes the other easier to maintain.

Frequently Asked Questions

Should I use capital letters in file names? Either works if you are consistent. All lowercase is simple and avoids differences between systems that treat case differently.

Is it safe to rename camera photos? Yes, as long as you keep the originals or ensure the renaming tool does not alter the image data. Keeping the original name somewhere, such as in a note, can help trace files later.

What if I do not know the exact date? Use the part you know with confidence and note the uncertainty in the description, such as a year with the word circa.
