Make sure a download arrived intact. Copy a file’s SHA-256 with one click, see SHA-1, MD5 or SHA-512 checksums for a batch of files, compare a file against a hash you copied from a website, or check every file listed in a SHA256SUMS file at once. Large files are fine — they’re read in pieces, not loaded into memory.

What it adds

• Copy SHA-256 — on one or more files (not folders). One file copies just the hash; several files copy one hash  name line each, the same format shasum uses.
• Show Checksums… — on one or more files. Pick SHA-256, SHA-1, MD5 or SHA-512 and the results open in a window with Copy and Save… buttons.
• Compare with Clipboard Hash — on a single file. Copy the published hash first; the plugin works out whether it’s MD5, SHA-1, SHA-256, SHA-384 or SHA-512 and tells you whether it matches.
• Verify Checksums — on a checksum file: one ending in .sha256, .sha1, .md5, .sha384 or .sha512, or named SHA256SUMS, SHA1SUMS, MD5SUMS, SHA512SUMS or CHECKSUMS. Every file it lists is checked in that folder, and a table shows OK, MISMATCH or MISSING for each, which you can copy or save as CSV. Both the shasum format and the BSD SHA256 (name) = hash format are understood.

See what’s inside your files without opening them one by one. Select a batch of photos and get camera, lens, exposure and GPS in one table; select an album and get artist, track and bitrate; select a folder of PDFs and get titles, authors and page counts. Save the table as CSV to open it in Numbers or Excel.

What it adds

• Show Metadata — on anything you select.
  • One file: every detail macOS knows about it, in a two-column table.
  • Several files or folders: choose Photos (date taken, camera, lens, aperture, shutter, ISO, focal length, size, GPS), Audio (title, artist, album, track, year, genre, length, bitrate, sample rate), Documents (title, author, pages, created, modified, creator app) or Everything. Folders are searched including their subfolders, hidden files are skipped, and up to 2,000 files are read. Columns no file has a value for are left out.

The result window has Copy and Save CSV… buttons. Details come from Spotlight, plus the EXIF and GPS data stored in photos, so photo details work even in folders Spotlight hasn’t indexed.

Get back the gigabytes your old projects are sitting on. Right-click a folder and Project Cleaner finds the build output and package folders your tools can recreate — node_modules, Xcode’s DerivedData, Python caches and the rest — shows how big each one is, and moves them to the Trash only when you say so. Changed your mind? Put them back from the Trash.

What it adds

• Find Build Clutter… — on a single folder. It looks through the folder and its subfolders and lists what it finds, largest first, with each folder’s size and file count. Then it asks whether to move them all to the Trash; click Move to Trash or Cancel.

It looks for:

• Always: node_modules, DerivedData, __pycache__, .pytest_cache, .mypy_cache, .gradle, .next, .nuxt, .parcel-cache
• Only next to the project file that makes them: target (with Cargo.toml), .build (with Package.swift), Pods (with Podfile)
• Python virtual environments: venv and .venv folders that contain pyvenv.cfg

It never looks inside .git, .hg or .svn folders, or folders named Library, Applications or System.

Write Files is what lets it move folders to the Trash. It only does that after you click Move to Trash.
