Frequently AskedQuestions

Check the following:

• Use a supported format: CSV, Excel (.xlsx), or text (.txt).
• If the first row contains headers, the tool will import them as folder names. Remove headers before import, or edit them after import.
• The first column should be the top-level folder, and each following column should represent one deeper nesting level.
• Files larger than 5 MB are not supported.
• The tool sanitizes unsupported characters and handles security-related edge cases automatically.

Most characters are allowed, but some are restricted by operating systems.

Avoid using / \ : * ? " < > | in folder names.

The tool detects these issues and notifies you. If anything is missed, invalid characters are sanitized automatically when generating the ZIP file.
