Hello! Is it possible to use the FIND command to discover large files that are a part of my previous backup(s)?
Context:
In order to save on storage costs, I’d like to manually PURGE some large files that I no longer need from previous backups. In most cases, though, I don’t know what the files are in advance - they could be ones that I deleted from my source disk at some point and no longer remember. I don’t want to impose a hard limit on the filesize (i.e. --skip-files-larger-than) because by default I don’t want to exclude backing up large files. The flow I’m envisioning is I run the FIND command with some filter that only returns files larger than some supplied filesize, look through the list and determine which I am comfortable deleting, then run the PURGE command with the filenames I chose. Is this currently supported?
I looked through the FIND options documentation and poked around the sqlite tables, but I couldn’t see anywhere to access this information.

“some filter” would need to be an external.
[Visualize backup data usage](https://forum.duplicati.com/t/visualize-backup-data-usage/6691/11) wound up there, and has some other ideas that may or may not fit your use.
If you don’t have `egrep`, i.e. this is Windows, pipe to [findstr](https://docs.microsoft.com/en-us/windows-server/administration/windows-commands/findstr) or [find](https://docs.microsoft.com/en-us/windows-server/administration/windows-commands/find) or use a capable editor like [Notepad++](https://notepad-plus-plus.org/).
