Sub-GHz Read RAW function does not completely erase when tapping Erase

[pliable]

Describe the bug
When using Read RAW under the Sub-GHz module, after it's done recording, tapping left will not erase the recording completely (it only seems to clear the screen). The raw recording will still appear under Saved

To Reproduce

1. Press OK button
2. Sub-GHz -> Read RAW
3. Press OK button to record
4. Press OK button to stop recording
5. Press Left to delete
6. (screen clears at this point)
7. Go back one menu
8. Select Saved
9. Raw_signal_ file will be present

Expected behavior
Seems like it should erase the RAW recording completely, not just clear it from the screen? At least that's what I gather it should do

Additional context
It make me sad :(

no, it shouldn't. when recording a RAW file, the file is immediately written to SD, since the flipper does not have enough RAM to store such large files, with a new recording, the old file will be overwritten and a new one will be written or renamed when saving. but if suddenly you pressed the wrong button, you still have a chance to save the record by renaming the temp file manually

And here I got all excited cause I thought I was helping :(. Perhaps, the wording needs to be changed to be more clear? I know I wasn't the only one who thought this was a bug.

Anyway, thank you for all your work 🙏🏼🙏🏼🙏🏼. Uh, I'll let you close it, I'll keep it open just in case lol
