LEDES Error: BF102 - Invalid Filename Error

What This Error Means

You are uploading a LEDES invoice, but the name of the file contains characters that are not allowed.

This error is about the file name — not the file content.

Brightflag only allows certain characters in file names.

You can use:

• A–Z (uppercase letters)

• a–z (lowercase letters)

• 0–9 (numbers)

• Spaces

• Hyphens -

• Underscores _

• Dots .

• Parentheses ( )

• Ampersands &

• Percent signs %

If your file name contains other symbols (for example: @, #, $, !, *), the upload will fail.

How to Resolve It

1. Locate the file on your computer.

2. Right-click the file and choose Rename.

3. Remove any unsupported symbols.

4. Use only letters, numbers, spaces, or the allowed characters listed above.

Example:

❌ Invoice#123@Client!.txt
✅ Invoice_123_Client.txt

After renaming the file, upload it again.
