A Simple Way to Keep Your Files Organized
A Simple Way to Keep Your Files Organized
A file named scan0047.pdf does not tell you much.
A file named 2024.01.09_signed services agreement.pdf
gives you a date and a description before you even open it.
That is the idea behind the filing system I recommend: make things easier to find later without making them difficult to save now.
This is not just for legal documents. The same approach can work for receipts, medical records, home repairs, work projects, correspondence, and other files you want to keep.
The key is consistency, not perfection.
Let the file name do some of the work
We have all saved something in a hurry, accepted the default file name, and assumed we would remember what it was.
A few months later, the downloads folder is full of files named
document.pdf, scan0047.pdf, and
final-final2.docx.
A descriptive name saves some of that guesswork. Adding a date also gives the file a place in the history of whatever you are keeping track of.
My preference is to start with the date, followed by a short description:
Suggested file naming format
yyyy.mm.dd_description.extension
For example:
A few examples
2026.02.18_plumber invoice.pdf
2026.03.05_annual physical lab results.pdf
2026.04.12_kitchen renovation budget.xlsx
2026.05.20_project proposal.docx
2026.06.08_family reunion.jpg
The extension—such as .pdf, .xlsx,
or .jpg—stays with the file. The naming pattern works
across file types; it does not require turning everything into a PDF.
Why I like putting the date first
Using the year, month, and day puts files in chronological order when the folder is sorted by name.
I use four digits for the year and two each for the month and day:
Year · Month · Day
2026.03.05
That makes it easy to scan a folder and see how a project, purchase, or exchange developed over time.
I also use lowercase throughout. There is nothing special about lowercase; it simply removes one more decision when naming a file.
The description does the rest. Ideally, it tells you enough to recognize the file without opening it. “Plumber invoice” is more useful than “invoice,” and “kitchen renovation budget” is more useful than “spreadsheet.”
Which date should you use?
I generally use the date that best identifies the item:
- For an email, the date it was sent.
- For a letter or invoice, the date shown on it.
- For meeting notes, the date of the meeting.
- For a photo, the date it was taken.
- For a working document, the date of the version I am saving.
The point is to connect the file to the event or document—not simply to the day it happened to land in your downloads folder.
Some files, such as an ongoing checklist or a reusable template, may not need a date at all. I would rather make a useful exception than force every file into a pattern that does not fit.
For correspondence, include who and what
For emails and letters, I find this format helpful:
Correspondence naming format
yyyy.mm.dd_sender to recipient~re subject.pdf
For example:
Email and letter examples
2026.03.14_smith to jones~re lease renewal.pdf
2026.04.02_contractor to smith~re kitchen estimate.pdf
I use last names for people and short, recognizable names for
organizations. The tilde (~) separates the people
involved from the subject.
That punctuation is just my preference. The useful part is being able to see the date, who was involved, and what the exchange concerned.
For an email I want to keep alongside other records, a PDF copy can be convenient. I save attachments separately so they are easy to find, too, and keep the original email.
Give related files a home
Clear names help, but so does keeping related files together.
I like folders organized around a subject, project, or activity:
Example folder names
home repairs
medical records
tax records
kitchen renovation
work projects
Within those folders, dated file names provide another layer of organization.
There is no need to build an elaborate folder structure in advance. A few folders you actually use are a better starting point than dozens of categories you have to think through every time you save something.
A few habits that make the system easier
Name the file when you save it
This is probably the most useful habit. Giving one file a clear name takes a moment. Renaming a backlog becomes a project.
Keep earlier versions when they matter
If I may need to refer back to an earlier draft, I save the new version separately rather than replacing it.
A date and a short description can distinguish them:
Keeping track of versions
2026.04.12_kitchen renovation budget draft.xlsx
2026.04.18_kitchen renovation budget revised.xlsx
If there are several versions on the same day, a version number can help:
Multiple versions on the same day
2026.04.18_kitchen renovation budget v01.xlsx
2026.04.18_kitchen renovation budget v02.xlsx
Not every small edit needs a separate file. The goal is to preserve versions that are useful, not create more clutter.
Keep an untouched copy when adding notes
For a document I want to highlight or annotate, I prefer making a separate copy:
Keeping the original and your notes
2026.03.05_annual physical lab results.pdf
2026.03.05_annual physical lab results annotated.pdf
That leaves both the original and my notes easy to identify.
Check scans before moving on
When saving a paper document digitally, I take a moment to check that the text is readable and all the pages are included. A useful file name helps only if the file itself contains what I need.
Start with the next file
You do not have to reorganize your entire digital life to try this.
Start with the next file you save. Give it a useful name and put it somewhere that makes sense. Then do the same with the next one.
If your current system works, there is no reason to change it just to follow someone else’s convention. This is simply an approach I find useful: a date, a description, and a sensible folder.
The goal is not a perfectly organized computer. It is being able to find what you need without opening twelve files to figure out which one is right.
