Hello
The files ‘Functional SAN Data-wal’ and ‘Functional SAN Data’ in the ‘Edge’ folder are data stored using the FileSystem API, a relatively rare web API that is not used on most sites. This data can take up a significant amount of space. Here are some steps you can take to manage this data:
Visit edge://settings/siteData in your Microsoft Edge browser.
Look for which sites are storing data there. You can use the “Sort By > Most data” option to see if there’s some site taking up a large amount of data.
You can use that UI to delete individual sites’ data, or you can use the “Clear browsing data” feature to clear data more globally.
Please note that you probably should not just delete the files from the disk using Windows Explorer.
Also, it’s worth noting that these files can be deleted, but they may still be generated. So, managing them through the browser settings as described above is the recommended approach.
