[Bug]: Cumulative ghost space in sd card

[Palloxin]

Problem description

So I use termux to mass replace text in files with regex.

The problem is, every time I send the command to replace, the sd card loses free space. And that space is undetectable by normal file explorers, even windows explorer.

Steps to reproduce the behavior.

Install termux, give storage permission, and then cd a path with html files, or txt idk.

Then u use this command to replace the text:
find . -type f -name "*.html" -exec sed -i -E 's/\baabb//g' {} +

Note: I have the sd card set as mi main storage location.

In the video u can noticed th free space going from 45.20Gb to 45.08Gb after the replacement.

I am reporting because I suddenly found my sd card free space to absolutely 0 bytes, I did everything from clearing cache and disintalling termux and other apps, nothing the ghist space couldnt be found.

So I put the sd into a pc and analized it with a specific program and...

I was finally able to get the space back.

note that the amount of files it checked dont even amount to 30mb, while the soace increases by 120mb every time

What is the expected behavior?

Every replacement doesnt occupy more space, or at least it is cleaned right afterward automatically.

or

-if the app is unistalled, that occupied space must be freed, which didnt happen

Its likely the exfat filesystem driver. My Android 7 does similar stuff where modified/deleted files go into corrupted state and consume space, and I need to run chkdsk /f/x on it every so often and delete the recovered files. I don't think its a termux issue. I don't know if a higher Android version fixed that as I don't have a device with a sd card slot for higher versions.

Can I kindly get the command for.mobile? Using the pc is a hassle

Oh btw, I used the check error thing, but I only recovered 10gb by doing so, then there was that 26gb file I had to eliminate myself, and needed a pc program to be even found

Yeah, same, you need to delete the files in the FOUND folders manually, that's what /f flag does.
