Files and disks apps for Windows
24 tools for files and drives on Windows: batch renamers and movers, duplicate finders, file splitters, hash generators and checkers, and ISO, VHD and VFD image makers. Each one does a single job.

DateStamp Modifier
Files and disksGive files the dates they should have. Set Created, Modified and Accessed to a date you choose, to the date each photo was taken, to the date in its file name, or shift them all by a few hours.

Random File Generator
Files and disksMake test files of an exact size in seconds. Random bytes, zeros or text, or real PNG, PDF, ZIP, DOCX and MP4 files that open in their own apps. Up to 10,000 at once, every one different, with a free-space check before anything is written.

ISOMaker
Files and disksTurn a folder into a disc image, and know what it will fit on before you write it. ISOMaker measures first: the size of the image itself — sector padding and path tables included — marked on a rail against a CD, a DVD, a dual-layer DVD and a Blu-ray, with the spare room spelled out. If the folder carries a boot file it offers to make the image bootable, and names the file it found. It writes real ISO 9660 with Joliet names, then reads the image back to check every file arrived.

Free Disk Space Monitor
Files and disksSee every drive's free space from the tray and hear about it before one fills up. A summary ring shows the drive with the least room, every drive gets a capacity bar, and a notch you drag decides when you get a notification.

Smart File Organizer
Files and disksTurn a folder full of everything into folders full of one thing. Images, Documents, Videos, Audio, Compressed and ten more categories, covering over 170 file types. It shows you the whole plan before it touches anything — which folder each file is going to and how many — and it copies rather than moves unless you say otherwise. Entirely on your PC.

File List Exporter
Files and disksTurn a folder into a file list you can actually use. File List Exporter writes the export to a real file — CSV for Excel, HTML to send to someone, Markdown or JSON for a developer, or plain text — with the columns you want: name, size, dates, type, folder and full path. Click a heading to drop a column and the preview updates as you go. Everything happens on your PC.

Hard Disk Performance Tester
Files and disksFind out how fast a drive really is. Hard Disk Performance Tester runs sequential and random 4K read and write tests with the Windows cache out of the way, and shows each result in MB/s, IOPS and latency, with every past run kept for comparison.

Quick ISO
Files and disksA folder becomes an ISO in one press. Drop a folder on the window and Quick ISO fills in the rest — the file name, a volume label the format actually accepts, and somewhere to save it — then waits for a single click. All three are on screen and all three can be changed, but none of them has to be. The result is an ordinary disc image: Windows mounts it on a double-click, and long file names survive because Joliet is written alongside. Nothing is uploaded.

Fast File Splitter and Joiner
Files and disksSplit a file, or join the parts back up, without reading anything first. Two buttons and three sizes is the whole app — no part counts to work out, no settings page, no options to get wrong. Bought once, and all of it works: no add-ons, no unlocks, nothing held back for a second purchase. Drop in a batch, press the button, and it is done. Everything happens on your PC.

MDF2ISO
Files and disksAn MDF is raw optical sectors, and the ISO is inside it. MDF2ISO reads the sector headers before it writes anything and tells you what the dump actually is: which of the three layouts Alcohol 120% wrote, how many sectors it holds, and how big the ISO will be. One sector is drawn to scale, so the bytes it keeps and the sync and error correction it discards are visible rather than described. Convert a whole queue in one run, on your PC.

Find Any File
Files and disksSearch your PC the way you'd ask a person. Type "spreadsheets I worked on this week" or "videos bigger than 1 GB" and Find Any File works out the kind, the dates, the size and the folder, shows what it understood as words you can click, and lists the matches as they are found. It can look inside documents and find duplicate files too.

Batch Smart File Renamer
Files and disksRename a whole folder with six rules that work together: add text, remove text, replace, change case, number in sequence, and add a date. Stack them — number a set of photos and stamp them with today's date in one pass — and watch every new name appear before a single file is renamed. Duplicates and illegal names are caught first. Entirely on your PC.

Any File Splitter
Files and disksSplit any file into pieces of the size you actually need. Pick the limit you are up against — 25 MB for an email, 700 MB for a disc, 4 GB for a FAT32 drive — instead of guessing how many pieces that works out to. Drop the parts back in later and it joins them into the original, byte for byte, without being told which job it is doing. A whole batch at a time, entirely on your PC.

File Hash Validator
Files and disksPaste the checksum a download page gave you and find out whether the file you got is the file they published. You never have to know which kind it is — the app works that out from what you pasted, and it takes MD5, SHA-1, SHA-256, SHA-512 or CRC32 in any spacing or capitalization. A mismatch shows what your file actually hashes to. Whole batches, entirely on your PC.

File Hash Generator
Files and disksWork out the checksum of every file in a folder, then copy the whole list out in one press. CRC32, MD5, SHA-1, SHA-256 and SHA-512, written in the standard two-space format that sha256sum and every checker built on it already reads — so the list pastes straight into a .sha256 file and publishes as-is. Large files are read in a stream. Everything happens on your PC.

File Hash Extractor
Files and disksTurn a folder of files into a folder of files each with its checksum written beside it. archive.zip comes out with archive.zip.sha256 next to it, in the standard format any checker reads — which is exactly the shape a download page or a release needs. MD5, SHA-1, SHA-256 and SHA-512, a whole batch in one pass, entirely on your PC.

Batch File Mover
Files and disksFind the files you want by name, contents, kind, date or size, then move, copy or recycle all of them in one go. Save a search as a rule that keeps a folder tidy by itself, even with the window closed, and undo the last move with one click.

File Encoder
Files and disksFind out which encoding a text file is in, repair garbled text like Café back to Café, and convert files to UTF-8, UTF-16, Windows-1252 or ASCII, one at a time or a whole folder at once. Everything happens on your PC.

Duplicate File Finder
Files and disksFind duplicate photos and files by what is inside them, not by their names, and free the space they waste. Copies are compared byte for byte, grouped into piles with the space each one frees, and laid out as prints so you can click the one to keep. Removed copies go to the Recycle Bin, so nothing is deleted outright.

VFDMaker
Files and disksMake virtual floppy disk images in seconds. Pick 720 KB, 1.44 MB or 2.88 MB, write the label on the disk, drop your files on it, and save a .vfd or .img file ready for virtual machines and emulators.

NoRecycle
Files and disksPull the lever and deleted files skip the Recycle Bin on the drives you choose. Push it back and the bin returns. Set the Recycle Bin to clear items older than a few days, or to stay under a size you pick, so it never fills your drive.

VHDMaker
Files and disksMake, attach and resize virtual drives. Pick a size on the drawn drive, choose VHDX or VHD, NTFS, exFAT or FAT32, and VHDMaker makes the file and formats it, ready in File Explorer. Windows asks for permission each time.

Downloads Organizer
Files and disksKeeps your Downloads folder tidy by itself. Every new file goes into a folder for its type a few seconds after it finishes downloading. Nothing is ever overwritten, and any run can be undone in one click.

Email Backup
Files and disksKeep a copy of your email on your PC. Email Offline Backup Tool saves every folder of your Gmail, Yahoo, iCloud, AOL, Fastmail, Zoho or other IMAP account as ordinary .eml or MBOX files, downloads only what is new, and lets you search and read the whole archive with no internet. It also opens old .eml, Outlook .msg and .mbox files and Windows Live Mail folders already on your PC.
