XF 2.2 How can I delete unnecessary attachments?

[USCSS_Nostromo]

After restoring the forum from an old backup, it turned out that the data of the attachments in the file system and the database are different (parameter data_id). I wrote a program that solved this problem. It looked something like this -

610997-4ea286b8fcbb24f986b049a468ed9727.data - 200

After that, the number of attachments increased by about 50%. How can I delete the unnecessary ones? Is there a system function or plugin for this?

And... Thanks to XenForo for properly formatting filenames, including a hash in the name, and ensuring the dependency between folder names and files.
This helped in recovering the content

XF\Cron\CleanUp::runHourlyCleanUp()

How does this function work?

Will it delete one of these two files?

611001-edc9eec0dad0e0a00e7662cac4ab72db.data and
610001-62cac4ab72db62cac4ab72db.data62ca.data

It will delete the file with the hash defined in the xf_attaxhment_data table. It won’t try others (by data_id prefix) if that’s what you are hoping.
