How to open .CDT files on iOS

Common issues
Windows says it can’t open the .CDT file
This usually happens when CorelDRAW (the expected application for CorelDRAW templates) is not installed or not associated with the .cdt extension.
- Install CorelDRAW, then open the file from within CorelDRAW (File → Open).
- Right-click the file → Open with → Choose another app → select CorelDRAW and optionally set it as the default for .cdt.
Wrong program opens the file (or it opens as “unknown image/x-coreldrawtemplate” on Linux)
Desktop environments rely on file associations; some systems map .cdt to image/x-coreldrawtemplate, but you may not have an app installed that can use that type.
- Use “Open With” and select the correct application if available; otherwise, open the file on a system with CorelDRAW installed.
- If you only need viewing, request an exported PDF from the file’s author.
The file opens but looks incomplete or errors out
The template may be corrupted, partially downloaded, or created in a way your setup can’t handle reliably.
- Re-download or re-copy the .CDT file and try opening again in CorelDRAW.
- Ask the sender to export the design to PDF from CorelDRAW to verify the content is intact.

Recover a deleted or lost .CDT file
If the file was deleted by mistake or the drive was formatted, data recovery software may be able to get it back. Stop writing to that drive right away, because new data can overwrite what you want to recover.

Security note
Treat .CDT files as untrusted input when they come from unknown sources: even though it’s a template, opening it requires a complex graphics parser, and malformed files can trigger application vulnerabilities.
