RAR, ZIP & 7Z : File Manager

A file manager that does the hard parts properly: it opens the archives you actually receive, previews a batch rename before it touches anything, and lets you take back a delete.

■ EXTRACT 8 FORMATS, HONESTLY

ZIP, RAR, 7z, TAR, GZ, BZ2, XZ and LZMA, plus tar.gz, tgz, tar.bz2 and tar.xz bundles.

Formats are detected from the file header, not the extension, so a tar.gz saved as .zip or a file you renamed still opens. When something really is unsupported, such as RAR5, you are told before extraction starts. No empty folder, no fake "Done".

Entry paths are checked as they are extracted. Anything that would escape the target folder is skipped and listed.

■ BATCH RENAME, PREVIEWED

Stack seven rules: find and replace (with patterns), add prefix, add suffix, number sequentially, change case, remove characters and tidy spaces. Apply each rule to the name, the extension or the whole file name.

Every new name appears as you edit. Duplicates, invalid names and clashes with existing files are flagged in red with the reason, before a single file changes. Chains like a→b, b→c are ordered automatically; a true swap is reported so you can do it in two passes.

■ TRASH: DELETES YOU CAN UNDO

Deleted files go to the trash first. Restore them to their original folder at any time within 30 days. The trash shows how much space it holds. Prefer instant deletes? Turn it off in settings. Very large files and files on servers are still removed right away.

■ CLEANER THAT ONLY REMOVES EXTRAS

Find files over 100 MB, installers you have already installed, and empty folders. See space by category: videos, images, apps, documents.

Duplicate finder groups files by size, then compares them byte for byte. Names are never used to guess. Nothing is deleted until you select it and confirm. Your photos and app data are never touched.

■ PHONE TO PC, NO CABLE

Start the built-in server and open the address, or scan the QR code, in any browser on the same Wi-Fi. Windows, Mac and Linux all work, with nothing to install on the computer.

A new 6-digit passcode is generated every time the server starts, so others on the network cannot browse your files. Choose whether the browser may upload or delete. Deletes are off by default.

■ NAS AND SERVERS

Browse SMB, FTP, SFTP and WebDAV like local folders. Copy and move between them and your phone.
