How to Stop Someone from Deleting My Files

If you share a Windows computer with family members, coworkers, students, or temporary users, one wrong click can delete the files you still need. GiliSoft File Lock Pro helps protect important files and folders so other users cannot casually delete, rename, overwrite, or open them without permission.

When This Problem Usually Happens

A shared office PC contains client files, invoices, reports, or project folders.
A family computer has photos, school work, tax documents, or private folders that other users can browse.
Employees or temporary users need access to some folders but should not change important originals.
Templates, forms, and approved documents keep getting overwritten or moved by mistake.
USB drives and external disks are plugged into other PCs where files can be deleted accidentally.

This page focuses on stopping unwanted deletion or changes. It is different from backup and recovery. You should still keep backups of important files.

How File Lock Pro Helps

1. Lock a file or folder when other users should not open it at all.

2. Write protect files when people may read them but should not delete, rename, overwrite, or edit them.

3. Hide private files and folders when they should not appear during normal browsing.

4. Protect folders on USB drives or external storage before sharing the device.

5. Use monitoring when you need clearer visibility into changes around important folders.

Why This Is Better Than Relying on Memory

Asking other people not to touch a folder works only until someone is in a hurry. File Lock Pro turns that fragile rule into a practical protection workflow for selected files and folders on Windows.

FAQ

Can I stop another Windows user from deleting my files?
File Lock Pro can help protect selected files and folders with locking, hiding, and write-protection controls so unauthorized users cannot casually delete or change them.

Should I use lock or write protection?
Use lock when the file should not be opened. Use write protection when users can read the file but should not change or delete it.

Do I still need backups?
Yes. File protection reduces everyday risk, but backups are still important for hardware failure, malware, or accidental loss outside the protected workflow.
