Every share gets a random short link like /s/ab12cd34. On any account, the free one included, you can replace that ending with a word of your choosing — filemv.com/s/portfolio reads a lot better on a slide or a business card.
Setting one
Open the share dialog and use the Custom link section. While you type, the field checks availability live. The rules:
- 3–30 characters, lowercase letters
a–z, digits and hyphens; - no leading/trailing hyphen and no double hyphen;
- reserved and offensive words are rejected, and a slug someone else already uses is taken.
What changes and what does not
A custom slug is an extra address, layered on top of the share:
- The automatic short link and the long link keep working unchanged.
- Password, expiry and everything else about the share apply to the custom link exactly the same.
- A password-protected share has no automatic short link (setting the password removes it), but a custom slug keeps working alongside the password.
Renaming: the old word stops working
If you change the custom slug, the previous one stops resolving immediately — anyone holding the old spelling gets a not-found page. As long as you do not add a password, the automatic short link never changes, so for anything printed or widely distributed, consider whether you will ever want to rename before choosing the custom form.
Clearing the custom slug simply falls back to the automatic short link.
You need an account
Custom slugs are set in the share dialog, so you need to be signed in; uploads made without an account get an automatic short link. Registering is free, and custom slugs are included on the free account.
