Do this in order
- Copy the damaged file to a new folder. Never repair in place.
- Look in WPS backup / autorecover locations (Backup Center or File → Restore, depending on version). On Windows this often lives under the Kingsoft folder in AppData.
- If you use WPS Cloud, check version history on another device.
- File → Open → select the copy → look for Open and Repair if the dialog offers it.
- Try the copy in Microsoft Word or LibreOffice as a second opinion — sometimes the other parser salvages XML.
- As a last resort, unzip a DOCX (it is a ZIP) and rescue
word/document.xmltext. This is messy but beats a blank page.
Turn on the safety net
Enable auto backup and a short interval. Save to disk every time you stand up. Cloud is not a substitute for a USB that fell behind a sofa if you never signed in.
Spreadsheets that refuse to open
Kingsoft’s academy article for Spreadsheets: update the app, confirm the format is supported, try Excel, then a repair tool. Isolated file + other files OK = corruption. Every file dies = install problem (startup guide).
Ransomware and disk failure
If filenames look encrypted, stop writing to the disk and restore from offline backup. WPS cannot decrypt ransomware.
Uninstall wipes local caches
Deleting %appdata%\Kingsoft to “fix” a crash also deletes local auto-backup copies. Export first. Uninstall notes.
