Your files,
all in order.

Yes. WinFile is now LeafFiles. From v2.0.1, the app folder is LeafFiles.app. The Terminal command at the top of this page backs up and migrates WinFile.app while preserving favorites, settings and the update channel. In-app updates may keep the old folder name; quit and rerun the installer to migrate it. Some historical screenshots show the old name.

Yes. LeafFiles is free and open source under the MIT license. It requires macOS 13.0 or later, with one universal download for Apple Silicon and Intel Macs. The app supports Simplified Chinese and English.

Install using the Terminal command at the top of this page. The script verifies the package checksum and app signature, keeps a backup and rolls back if installation fails. The app is not Apple-notarized; if macOS still warns about an unidentified developer, follow its instructions in System Settings → Privacy & Security to allow opening.View the Terminal install command ↑

No. Scanning only lists candidates and selects nothing by default. Confirmed files are moved to Trash after identity and usage checks. Running apps, protected data and uncertain items are kept. General cleanup and other apps’ cache cleanup can be undone with ⌘Z in the current session. WeChat attachments can be recovered from Trash. Moving files to Trash does not immediately free disk space; usage figures are estimates.

The list comes from readable cleanup folders on this Mac, rather than every installed app. Helper, updater and extension components are not listed separately. WeChat scans local attachments. Baidu Netdisk also supports actual download folders, with a saved custom location. Other apps are limited to identified caches and logs, preserving accounts, settings, databases and offline content. Use Refresh app list after new folders appear.

Open Storage Cleanup → Software Cleanup, select Baidu Netdisk and choose its actual download folder. Common locations are detected automatically, and custom folders are saved. General Cleanup uses that folder too. Only files downloaded to this Mac are scanned; review what you want to keep before confirming cleanup.

Only locally downloaded attachments and supported cache locations are scanned. Chat databases are not read or decrypted. Files that exist only on your phone or have not been downloaded to this Mac will not appear. You can add custom attachment folders; date filters use file modification times. Preview attachments before confirming a move to Trash.

Unlock your phone or tablet, connect with a data-capable USB cable, select File Transfer and allow access if prompted. No USB debugging, ADB or extra tools; connection changes are detected automatically. The device controls visibility; Android/data and private app folders may be hidden. If another app is using the device, quit Preview, Photos, Image Capture or the transfer app completely. Closing a window may not release USB access; LeafFiles retries automatically.Read the connection guide ↗

From 1.4.1, double-click or choose Open for Android images and PDFs to use LeafFiles’ Quick Look panel. Space previews them too. Files are verified and use reusable read-only local copies; edits are not sent back to the device. Download first to open or edit them in an external app.

This fix avoids automatically launching Preview and its camera importer, which can claim the USB interface used by MTP. An external camera-import or transfer app you open yourself can still claim the device. Quit the app holding access and LeafFiles recovers automatically.

No. The built-in player reads MTP byte ranges on demand into a shared video-data cache capped at 32 MiB, without saving a full video file. Closing or disconnecting cancels reads and frees the cache. This is not a total memory limit or a promise of zero operating-system swap writes. Unsupported codecs or devices report an error without a download fallback.

Other documents still need read-only local copies. The cache targets 2 GiB / seven days and is cleaned when preparing files; copies opened in the current session are retained for external apps and may exceed the target. Download explicitly for external players or unsupported formats. Manual downloads are never automatically deleted.

Extract ZIP/ZIPX, RAR (including RAR5), 7Z, TAR, CAB, ARJ, LZH/LHA, CPIO, AR, DEB, RPM and XAR, plus GZip, BZip2, XZ, Zstandard, LZMA and Unix compress streams and TAR combinations. Passwords, volumes, batches and cancellation are supported. Extraction is staged and name conflicts get a separate output. Codec/encryption variants depend on the engine, so not every proprietary ZIPX codec is guaranteed. Packages are never installed. Archive creation remains ZIP.

From v2.0.3, new ZIPs exclude .DS_Store, ._* and __MACOSX at every level. Other hidden files such as .git, .env, .gitignore and .config, empty folders and symlinks are retained. This applies to folders, direct multi-selection and combined selections from different directories. Only archive contents are filtered; source files remain untouched. Selecting only metadata shows a clear message without creating an empty archive.

Yes. Double-click a local archive, press Space or choose Preview archive to browse folders, breadcrumbs and search. Double-click a member or choose Open with default app; LeafFiles associations take priority over the macOS default. Direct opening requires a file smaller than 64 MiB. Files at the limit, unknown sizes and links prompt extraction first. Single-click selects; Space and View selected file retain embedded Quick Look. Extract All offers a destination picker; extracting selected members is not supported.

Listing ordinary archives does not extract files. Opening a selected member creates a read-only copy; edits are not saved to the archive. External copies survive closing the archive window and are reused in the same preview session. Later file opens reclaim older sessions using a seven-day / 512 MiB target. Files handed off during the current run stay protected, so the target is not a hard cap. Embedded preview copies are removed on close. Compressed TAR intermediates are limited to 512 MiB; listings to 100,000 entries / 32 MiB.

From v1.2.0, LeafFiles checks for updates on launch. Install, skip a version or choose a reminder, or check manually in the app. Both update archives and the feed are verified with Ed25519 signatures. Upgrade older versions using the Terminal install command at the top of this page.
