Shown with sample data. ### What it does on a PC Pick a part, or keep scrolling. - New - Servers - My disk is full - Move to a drive - Free up space - Storage - Duplicates - Startup - Updates - Security - Live monitoring - Recovery New in ByteSweep 3.3 ### Your servers, and a full disk rescued ByteSweep 3.3 looks after the servers you run ByteSweep CLI on, frees space step by step when your own disk is full, warns you before it fills, shows what an update changed, and moves big folders to another drive. #### Your servers Every server you run ByteSweep CLI on, on one page, read over your own SSH: how full its disks are, waiting updates, backups and what needs a look. #### My disk is full When there is no room left, ByteSweep frees space fast from what apps make again by themselves, and stops as soon as there is room. Your own files are left alone. #### Alerts A warning before a disk fills up, sent to Slack, Discord, Telegram, email or a web address you choose. Alerts stay off until you add a place, and send nothing else. #### Before / after Take a snapshot before an update or an install, then come back afterwards to see what it changed. #### Move to a drive Copy a big folder to another drive, check the copy twice and leave a link so your apps still find it. Only then is the space freed. Bring it back whenever you like. #### For developers Cards for local databases, scheduled jobs and local web servers, and a list of who can log in to this PC. Also new: a virtual machine's files in Storage open that machine's card, so a disk image is never removed on its own while the machine still needs it. Move to a drive takes the place of Archive to a drive, and what you archived before is listed there too. ### Look after your servers Add a server you reach over SSH and ByteSweep CLI runs on, and it sits in ByteSweep beside your own disk. ByteSweep CLI is a separate product: try it for 3 days, then it needs a licence of its own. - How full each disk is, and when it will fill - Waiting updates, backups and services that failed - Clean with Undo, clear old logs, install updates or plan a maintenance window - Databases, websites, jobs, who can log in, alerts, backups and snapshots, each on its own tab [Needs ByteSweep CLI on the server](https://bytesweep.app/cli.html) ### Every problem, explained Each finding opens its own page: what it means, why it matters and the steps to fix it. - A button that does it for you - Or the command, to copy and run yourself - You see what will happen before anything runs ### My disk is full When the disk has no room left, ByteSweep goes through the safe steps one at a time and stops as soon as there is room again. - Temporary files, caches and update leftovers that apps and Windows make again - Says how much it freed, and how much is free now - Your documents, photos and other files are never touched - Removed for good, so the space comes back at once. To choose file by file with Undo, use Clean. ### Move to a drive Big things you rarely open, such as a photo library or an old project, go to another drive and stay within reach. - Every file copied, read back and checked twice - A link left in its place, so your apps still find it - Only then is the space freed - Bring it back whenever you like ### Tidy folders, your phone and your other computers The latest updates sort messy folders, connect ByteSweep to your other devices, and keep an eye on space for you. #### Organize a folder Downloads or any folder, sorted into tidy subfolders by kind, by date, or photos by the place they were taken. You see the plan before a file moves, and Undo puts it all back. #### Send to your devices Files, folders, a note or a link to your iPhone, Android phone or another computer, straight over your Wi-Fi. One device or several at once. It is in File Explorer’s right-click menu too. #### Your phone, on the big screen View your phone shows every photo and video on it, and plays them. Clean your phone goes through its duplicates, big videos and screenshots; the phone asks first and deletes only after its own confirmation. #### Move to a new PC Clean first, choose the folders, and send them to the new PC over Wi-Fi. #### Space Guard Turn it on and ByteSweep keeps the disk from filling up: under your limit, it cleans the safe part, tells you, and keeps an Undo for a day. #### Do I need a new PC? Check-up answers it for space: how long until the disk is full, and how much longer a clean would buy you. #### Files on your drives, found A Library search also finds files on drives you have catalogued, archived ones too, even when the drive is not plugged in.

These are the folders underneath. ByteSweep measures and explains each one. #### Windows Update leftovers Update packages downloaded before installing, which are never used again once installed. `SoftwareDistribution\Download`. #### Delivery Optimization cache Pieces of updates kept to share with other PCs. A cache; Windows trims it on its own schedule, slowly. #### Component store (WinSxS) Superseded system components kept after updates. Cleaned the supported way, through DISM, never by deleting files. #### Windows.old and upgrade files The previous Windows installation kept after a feature upgrade, often 20 GB or more, plus `$Windows.~BT`. #### Crash dumps `MEMORY.DMP` and minidumps written after a blue screen, useful to a developer and to nobody else. #### Temp files and thumbnails User and system temp folders and the Explorer thumbnail cache, which rebuilds itself. #### Browser caches Chrome, Edge, Firefox and Brave caches. History, cookies and autofill are listed separately and cleared only if you choose them; saved passwords and bookmarks are never touched. #### Game launchers Caches and leftover installers from Steam, Epic Games, the EA app, GOG and Battle.net. Games and saves are left alone. #### Developer folders `node_modules`, `bin` and `obj`, Rust and Maven `target`, Gradle builds and Python virtual environments in projects you have not touched for months.

[How it decides what is safe](https://bytesweep.app/how-it-works.html#safety) ### Questions #### Is ByteSweep a good CCleaner alternative? ByteSweep covers what CCleaner is used for, such as temp files, browser caches, startup apps and app updates, and adds a storage analyzer, duplicate finder, file recovery and a 7-day undo for what it can put back. It leaves the registry alone, and it is a one-time $29.99 with no subscription and no bundled offers. #### Is it safe to delete the Windows Update cache? Yes, once the updates are installed. The files in `SoftwareDistribution\Download` are the installers Windows downloaded; Microsoft's own troubleshooter clears that folder. Files of an update still in progress are locked, and ByteSweep skips them. #### Can I delete Windows.old? Yes, if you do not plan to roll back to the previous version. It is removed automatically after about ten days; deleting it earlier frees the space now but ends the option to go back. ByteSweep marks it review first and explains that trade. #### Does ByteSweep clean the registry? No. Registry cleaning does not make Windows faster, and ByteSweep from the Microsoft Store leaves the registry alone. It does point out startup items whose program is gone, and opens Windows Settings so you can turn them off. #### Does ByteSweep need administrator rights? Not to install or to run. A few tools ask for elevation when you use them: component store cleanup, clearing event logs, all-users startup entries and services, BitLocker status, and recovery from a raw drive. #### Does ByteSweep for Windows send data anywhere? No. There is no telemetry and no ByteSweep server. The Updates page talks only to the package sources it names (winget, Microsoft Store, Chocolatey, Scoop). Licence activation contacts Dodo Payments, our payment provider. The only other network use is the connectivity test and ping, which you start yourself.
