Rules

A rule combines an extension condition, an optional regular expression and a destination. Mouzi checks enabled rules from the lowest priority number to the highest and uses the first match.

Rules are global. The same list is applied to every watched folder.

Extension matching

Enter extensions without a leading dot. Separate several values with commas:

Extensions: pdf, docx, odt
Destination: Documents

Extension matching is case-insensitive, so Report.PDF matches pdf. The special value * matches any extension and is useful as a final catch-all rule.

File-name patterns

The optional Pattern field is a Rust regular expression matched against the complete file name, including its extension. There is no separate plain-text “contains” mode.

Extensions: png, jpg
Pattern: ^Screenshot.*\.(png|jpg)$
Destination: Images/Screenshots/{year}

Patterns are case-sensitive unless you add (?i):

(?i)^invoice[-_ ].*\.pdf$

When both extensions and a pattern are present, both must match. An invalid regular expression will not match files, so test a new rule in Manual mode first.

Priority and first match

Lower numbers run first. Set the numeric Priority field rather than relying on the visual position of a row.

Priority	Match	Destination
10	pdf and (?i)invoice	Documents/Invoices
20	pdf	Documents/PDF
999	*	Other

An invoice reaches the first rule and stops there. Other PDFs reach the second rule. Everything else can fall through to the catch-all.

Enable and disable

In public version 0.1.5, edit a rule and clear Enabled to disable it without deleting it.

Coming in 0.1.6: every rule row has a quick enable/disable control.

Destinations and conflicts

Relative destinations such as Documents/PDF are created inside the source watched folder. Absolute paths such as D:\Archive or /mnt/archive are also supported, including moves to another drive.

Mouzi creates missing destination folders. If a file with the same name already exists, it keeps the existing file and adds a Unix timestamp to the file being moved.

See dynamic paths for destination placeholders.

Import and export

Use Settings → Rules to export all rules as JSON. Import can either append rules or replace the current set. Keep an export before using the replace option; replacing is intentional and cannot be undone from History.

Starter rules

The first run includes categories for images, documents, archives, installers, music and videos, followed by an * catch-all. You can edit or delete every starter rule.
