backup file size different than what is being indicated

It sounds like the download might have been incomplete if the actual file size is significantly smaller than expected. Here are a few steps to check and resolve this issue:

1. Double-check the file size of the downloaded .wpress file on your local machine. If it’s only 27MB, it likely didn’t download correctly.

2. Try downloading the backup file again from the All-in-One WP Migration -> Backups tab. Ensure your internet connection is stable during the download.

3. If the download keeps getting interrupted, consider using a download manager like uGet.

4. Ensure that there is enough space on your local machine to accommodate the full 3GB file.
