Is there a way to recover deleted files/data from apps?

If you happen to delete some of internal files from your app by accident, can you retrieve them somehow? Using any Windows app? I deleted some from this one:

‎nPlayer Plus

‎** nPlayer officially supports DTS (DTS HD ), DTS Headphone:X, Dolby (AC3, E-AC3). ** The 'Upgrade' In-App is just only for the users who already purchased nPlayer of the version 2.6.5 or the previous version. The first time buyer can use the full functions without any upgrade.(In-App purchase...

apps.apple.com

But the contents (in this case a few TXT files) were only available inside this app. I got an older copy, but it's outdated.

I had an issue with a pendrive and the TXT files are all garbage now, after running chkdsk this happened with it. Also the pendrive isn't being recognized anymore, making Win10 unresponsive.

Anyway, is there a way to run any software to retrieve data you delete (files) from such players? Or is this impossible? It was not saved in the iCloud backup.

I spent more than 1 hour scanning with this FoneLab Windows app:

How to Recover/Restore Deleted Apps and App Data on iPhone/iPad

Upset when you deleted apps from your iPhone without saving the data? Read this article and learn how to recover recently deleted apps and data on iPhone.

And still it only showed the current documents stored in this nPlayer app, not the deleted ones.

So apparently whatever these softwares call "recovery" is limited to images and perhaps other stuff such as deleted notes, not random types of files you delete, in my case TXTs. I made the mistake of deleting these inside nPlayer and now I think there's no way of recovering. Once you delete it's gone.

The methods of recovering using iTunes or iCloud are useless for me because I haven't plugged into my PC or made any online backup of nPlayer's internal data.

What I meant by recovering was to scan the entire iPAD in the hope of finding deleted files, like forensic analysts do when you erase an entire HARD DRIVE or delete any file from Windows permanently and the file isn't 100% gone days later. So in my case I hoped this was possible for the iPAD Pro 10.5. Apparently it isn't. Even worse considering this was a really small file.

As for my pendrive when it worked (because now it's randomly refusing to be read by Windows when I plug into my USB ports) I used a program called RECUVA and after a deep scan it says some of these files can't be recovered because they were overwritten by newer versions, or the ones with the "excelent" status for recovery I already know are the ones corrupted by CHKDSK with the garbage text "NUL" inside them, replacing partially or totally their contents.

In sum I doubt I will get anything from this pendrive and/or iPAD. I'll have to reconstruct the missing data and use an older backup from the affected files which I currently had stored in a 2nd pendrive...

For Windows users this app is also useful to check whatever has changed: https://www.sourcegear.com/diffmerge/
