Choosing what belongs in a first Windows backup
For a first Windows backup, start with the files you create and would hate to lose: Documents, Desktop, Pictures, Downloads, and any custom folders where you save work. Add the working data people forget until it’s gone, like browser bookmarks, email files, app data, and project folders from creative or office apps. Skip installed programs, temporary files, and anything you can reinstall or recreate easily.
Prerequisites
- A Windows PC with the folders and apps you want to check
- Access to the account you normally use on that PC
- A backup destination, such as an external drive or another storage location
- A few minutes to open File Explorer and the apps you use most
Steps
- Open File Explorer and look at the folders you use most often.
Check Documents, Desktop, Pictures, Videos, Downloads, and OneDrive if you keep local files there. If a folder holds files you would not want to remake, put it on your backup list.
- Open a few of your recent files and note where they are actually saved.
Use the file path shown in the app or in File Explorer. The goal is to find the real working folder, not just the default location you expect.
- Add any custom folders where you keep work.
This might be a Projects folder, a client folder, a writing folder, or anything else you made yourself. If you regularly save source files there, back up that folder first.
- Check the data that is easy to forget until something breaks.
Look for browser bookmarks, email files, app data, notes, game saves, and project folders from creative or office apps. If the app stores the source material, presets, catalogs, or profile data locally, include that too.
- Leave out the things you can replace quickly.
Do not spend your first backup on installed programs, temporary files, caches, or downloads you can get again. If a file is both easy to replace and not tied to your own work, skip it for now.
- Make a keep, skip, or check-later list before you run the backup.
Mark personal files and active work as keep, installer and cache folders as skip, and anything inside AppData or another unclear path as check later. Then confirm the folder actually contains the files you care about before you include it.
Start with the files you would hate to lose
The easiest rule is simple: if recreating a file would take hours or be impossible, it belongs in your first backup. That puts your own work ahead of everything else. A contract draft, family photos, a school paper, a budget spreadsheet, or a design project matters far more than a copy of an app you can reinstall later.
Start by thinking about what you would panic over if the PC stopped working tomorrow. Those are the files to protect first. Personal files usually live in folders you made yourself or in the standard Windows folders people use every day. You do not need the perfect backup list on day one. You only need a solid first pass that catches the data you cannot easily replace.
Check the usual Windows folders first
Begin with the common places where Windows stores personal files:
DocumentsDesktopPicturesVideosDownloadsOneDriveif you keep local files there
These folders often hold the bulk of what matters on a home or work PC. Documents is usually where reports, spreadsheets, notes, and school files end up. Desktop often has shortcuts, but many people also save real files there out of habit. Pictures and Videos are obvious candidates because media files are hard to replace once they are gone.
Downloads is more mixed. It contains installers and throwaway files, but it can also hide receipts, PDFs, scans, and files you downloaded for a project. If you are unsure, sort through it rather than backing up the whole folder blindly.
If you use OneDrive with local sync, check whether the files are stored only in the cloud or also on your PC. If a folder is available offline, include it in your backup plan so you have a local copy as well.
Look for your own work folders, not just the default ones
Default folders are only part of the picture. Many people save work in places that have nothing to do with the standard Windows library folders. A freelance writer might keep article drafts in C:\Work\Writing. A photographer might store shoots in D:\Photos\ClientA. A developer might have project folders inside a custom Projects directory. An accountant might keep client files in a folder outside Documents for easier sorting.
The trick is to look where your files are actually saved, not where you assume they are saved. Open the app you use for the work, check the recent file list, and see the folder path on a few current files. If you regularly open the same project folder each week, that folder belongs in the first backup.
This matters because many apps let you save anywhere. If you have moved files off the default folders, Windows will not guess that for you. Back up the folder that holds the source files, not just the exported copies.
Don’t forget the small things that are hard to rebuild
Some of the most annoying losses are not big documents at all. They are the small bits of working data that make your setup feel like your own. Browser bookmarks are a common example. So are saved passwords export options, browser profiles, email data files, notes, and game saves.
If your browser stores bookmarks and settings locally, include the browser profile or export the bookmarks first. If you use a desktop email app, look for its data files or mailbox store. If you keep notes in an app that stores local notebooks, back those up too. Game saves can live in hidden folders or under AppData, so check the specific game or launcher if you care about progress.
Creative and office apps can store more than the finished file. They may keep templates, custom brushes, presets, catalogs, caches, or project databases. Some of that is replaceable, but project files and catalogs usually are not. If the app has a built-in export or backup option, use it for data you truly need to keep.
Skip the stuff you can reinstall later
Do not spend your first backup on installed programs, system files, or things you can fetch again quickly. Applications can usually be reinstalled from the original installer or the Microsoft Store, and Windows itself is not something you should copy by hand as your main backup plan.
Temporary files and caches also usually belong on the skip list. They may help an app run a little faster, but they are not the source of your work. Browser caches, update files, leftover installers, and similar clutter do not help much if the real goal is protecting your data.
Downloads that you can easily get again, like software installers or duplicate copies of public files, are also low priority. If a file is both easy to replace and not tied to your own work, leave it out for now. That keeps the first backup smaller and much easier to understand.
Make a quick keep, skip, or check-later list
A simple sorting method keeps this from turning into a weekend project. Go folder by folder and label each one as keep, skip, or check later.
Keep it if the folder holds personal files, active work, or anything with real history, such as:
DocumentsPictures- a
Projectsfolder for school or freelance work - app data that contains notes, catalogs, or browser profiles
Skip it if the folder mainly contains installed apps, caches, temporary files, or reinstallable downloads.
Check later if you are not sure. That usually means a folder inside AppData, a software-specific folder, or a path you do not recognize. Open the app, find where it saves files, and decide based on that. If the folder contains the source material for your work, keep it. If it only contains supporting files the app can rebuild, it can wait.
This simple sorting pass prevents two common mistakes: backing up too much junk, or missing the one folder that actually matters.
Do a final check before you run the backup
Before you start the backup, scan the list once more and make sure you have at least one copy of each file type you care about: documents, photos, videos, project folders, and any app data you cannot recreate easily. Then check the folders you actively use each week. If you worked on it recently, it should be on the list or at least on your check-later list with a clear reason.
A fast review can be as simple as opening File Explorer and confirming that the paths you saved are the real working locations, not just shortcuts or empty parent folders. If you use cloud sync, check whether the files are already online or only stored locally. If they exist only on the PC, back them up now.
Once the list feels complete, you are ready to run the backup with confidence. You are not trying to preserve every byte on the machine. You are making sure the files that matter most survive the first failure.
Conclusion
After this first pass, your backup should focus on the files you create, edit, and would miss immediately if they were gone. Start with the standard folders, add your own work locations, include the small data that is hard to rebuild, and leave the reinstallable clutter out. If you want to be extra careful later, you can always expand the backup set after you have the important stuff covered.
Frequently Asked Questions
Should I back up the whole Windows drive on my first try?
Usually no. A first backup is easier to manage if you focus on personal files and working data instead of copying the whole operating system, apps, and temporary files.
Where are browser bookmarks stored?
That depends on the browser. Many browsers sync bookmarks to an account, but some also keep local profile data on the PC. Check the browser’s sync and export options, then back up the profile if needed.
Are Downloads worth backing up?
Sometimes. If Downloads mostly contains installers and junk, skip it or clean it first. If it holds receipts, PDFs, scans, or project files you still use, keep those files.
What if I use an app that saves files in AppData?
Back up the specific folder the app uses for your data, not the whole AppData tree unless you know you need it. Many apps store settings and cache there, but only some store real work files there.
