# File Matching

Javinizer will by default attempt to clean the filenames of downloaded files and match them to their Movie ID which normally appears in the form of ID-###. 

To reduce the likelihood of false matches, Javinizer requires that the filename match is exactly the ID that appears on the scraper source. 

For example, `ABP-420.1080p.mp4` will be automatically cleaned to `ABP-420` when matching. This must exactly match the movie ID `ABP-420` that is displayed on your selected scrapers.

In some cases, the default file matcher will fail to match the file due to edge case filenames or the ID listed on the scraper source does not follow the standard ID format. In these cases, you will likely need to sort using the `-Url`  or `-Strict` parameters.

The `-Strict` parameter works by forcing the matcher to ignore the default filename cleaning logic and use the exact filename. 

For example:

* `Javinizer -Path .\ABP-42.mp4` will automatically clean the file ID to `ABP-420`
* `Javinizer -Path .\ABP-42.mp4 -Strict` will use the filename as the ID as `ABP-42`

One thing to keep in mind is that `-Strict` will not support multi-part sorting due to the nature of how it matches the filename exactly.

## Multi-part video support

Javinizer supports sorting multi-part videos. When sorted, all multi-part videos will be renamed in the format: `ID-###-pt#`.

The following filename formats will be detected as a multi-part video.

| FIlename Format  | Example                    |
| ---------------- | -------------------------- |
| ID-###\[a-iA-I]  | ID-030A, ID-030B           |
| ID-###-\[a-iA-I] | ID-030-A, ID-030B          |
| ID-###-\d        | ID-030-1, ID-030-2         |
| ID-###-0\d       | ID-030-01, ID-030-02       |
| ID-###-00\d      | ID-030-001, ID-030-002     |
| ID-###-pt\d      | ID-030-pt1, ID-030-pt2     |
| ID-### - pt\d    | ID-030 - pt1, ID-030 - pt2 |
| ID-###-part\d    | ID-030-part1, ID-030-part2 |
| ID-###\_\d       | ID-030\_1, ID-030\_2       |
| ID-###\_0\d      | ID-030\_01, ID-030\_02     |
| ID-###-cd\d      | ID-030-cd1, ID-030-cd2     |
