Protect Files from Being Overwritten

Overwriting files is one of the easiest mistakes to miss. A user saves a new report over the approved version, replaces a template with a filled copy, exports a file using the same name, or copies an older folder onto a newer one. GiliSoft File Lock Pro helps keep selected originals readable while reducing unwanted edits, overwrites, renames, moves, and deletions.

Files That Should Not Be Replaced

Some files are meant to be opened often but changed rarely. Normal Windows file attributes may be too easy to remove, and shared folders make it simple for someone to save over the wrong item.

Office templates, forms, contracts, price lists, and policy documents.
Approved reports, finance spreadsheets, design source files, and project archives.
Training materials that students or staff should view but not modify.
Backup folders where an older copy should not replace the current version.
External-drive folders used for client delivery, field work, or partner handoff.

How File Lock Pro Helps

1. Use write protection when files should remain readable but not editable or replaceable.

2. Lock folders when only authorized users should update the originals.

3. Hide sensitive source folders when casual users should not browse or clean them up.

4. Apply protection to selected folders instead of blocking normal work across the whole drive.

This page focuses on preventing overwrite mistakes before they happen. If a file has already been overwritten, check backups or version history first, then protect the source folder going forward.
