# Export Download Debugging
Use this when an export or download appears to run but produces an empty,
missing, or unusable file. It is tuned for browser previews, iframe capture,
and Electron shells.

debugging the destination path. A 0 KB file often means the native picker or
host created the target file, then the write failed or was blocked.
