Chinese & CJK file search

Find files by their Chinese,
Japanese or Korean names

CJK filenames are written without spaces, so many search tools match them unevenly — they may want the whole word, split the term in the wrong place, or skip Chinese inside documents. PowerFind matches CJK text as a substring: type 報告 and it finds 年度報告2026. No word segmentation, across filenames and content, entirely on your computer.

Why CJK search is a different problem

English is spaced into words a search engine can pick out. CJK text is one continuous run of characters, so a tool has to decide how to match it — and that decision is where results differ.

No spaces to split on

年度報告2026 is a single unbroken string. There is no space telling a tool where 報告 begins, so plain word matching can miss it.

Segmentation can guess wrong

Tools that split CJK into words rely on a dictionary. When a name, an acronym or a new term isn't in it, the split — and the match — can land in the wrong place.

Content is often the gap

Even when filenames work, full-text support for CJK inside documents varies. PowerFind applies the same character-pair matching to content, so the text is found either way.

Type part of a name, in Chinese

A two-character query is matched anywhere in the text, so you don't have to remember the exact wording of a filename.

Substring, not whole-word

Match a CJK phrase in the middle of a filename, not only at the start. Two characters are enough to narrow millions of files as you type.

Filenames and content, one bar

The same query runs over in-memory filenames and a local full-text content index, so the phrase is found on the name or inside the document.

Frequently asked questions

Why is searching Chinese, Japanese or Korean files harder than English?

English words are separated by spaces, so a search tool can split a filename into words and match them. CJK text is written without spaces — 年度報告2026 is one unbroken run of characters. To search it well, a tool has to either guess where the words start (segmentation, which can guess wrong) or match on characters directly. Because of this, support varies between tools: some need the whole word, some split terms in a way that misses partial matches, and some index only Latin text inside documents.

How does PowerFind match Chinese without word segmentation?

PowerFind breaks CJK text into overlapping character pairs and matches on those, so a two-character-or-longer query is found anywhere in the text — not only at the start of a guessed word. That means typing 報告 finds 年度報告2026, and 發票 finds 電子發票明細. There is no dictionary to keep updated and no segmentation step to get wrong; it works the same for Chinese, Japanese kanji and Korean hanja.

Does PowerFind search Chinese inside file contents, or only in filenames?

Both. Filename search runs from an in-memory index for instant results as you type. Content search reads the text inside documents — PDF, Office and plain-text files — into a local full-text index, and applies the same CJK character-pair matching. So you can find a Chinese phrase whether it appears in the filename or deep inside a document.

Does searching my Chinese files send anything to the cloud?

No. The filename and content indexes are built and stored on your own computer, and every search runs locally. PowerFind needs no account and makes no network connection to search. Your filenames and document contents stay on your machine.

Is the interface available in languages other than English?

Yes. The interface ships in 7 languages, so you can read the app in your own language while searching files in Chinese, Japanese, Korean or any mix. The core search is free forever, with no ads and no time limit.
