You can filter the files before uploading to Azure using the "Filter Files by adding SOQL filter conditions" feature. Follow these steps:
- Go to the "Migrate Files/Attachments To Azure" Tab.
- Look for the "Migrate Now" section.
- Under the "Migrate Now" section, you will find the option for "Filter Files by adding SOQL filter conditions" for both files and attachments.
- Enter the query in the box and click on the "Search" button.
- A table will be rendered with filtered files only. Here you can easily migrate selected files or all files using the "Migrate All" or "Migrate Selected" buttons.
