Choose clear file names that are easy to share

A descriptive name makes a file easier to recognize without opening it and helps distinguish versions. A simple convention can also make shared folders easier to manage. Requirements differ across systems and upload forms, so follow the recipient’s instructions.

Build a useful name

Start with the subject, add a relevant detail and finish with the file type. Fictional example: `2026-09-11-rental-agreement-v01.pdf`. Describe the contents rather than a temporary circumstance.

Choose characters with compatibility in mind

For files used across different systems, letters, numbers and simple separators such as hyphens are a practical choice. Accents, spaces and punctuation are often supported, but some forms or scripts have their own rules. If an upload fails, read its message and adjust a copy of the name.

Keep dates and versions in order

  • Use year-month-day, such as `2026-09-11`, when a date helps sort files.
  • Label versions `v01`, `v02` so their sequence is clear.
  • Keep the real file extension and do not rename a document to disguise its format.

Protect personal information

Avoid putting identity numbers, addresses or other unnecessary personal data in a file name. Check the upload portal’s naming rules and required format as well.

Frequently asked questions

Should I always remove accents?

No. That is not a universal rule. A simplified name can help when files move between systems or when an upload form reports an error.

Are hyphens better than underscores?

Both can separate words. Choose a convention for the folder and use it consistently.

Which date format helps sorting?

Year, month and day in that order (YYYY-MM-DD) sort chronologically when arranged alphabetically.
