Affected app version

1.0.0

Affected Android/Custom ROM version

Android 11

Affected device model

Nokia TA-1157

How did you install the app?

F-Droid / IzzyOnDroid

Steps to reproduce the bug

1. Have a long list of previously recorded files (68 in my case, see additional info for more on this).
2. Rename a file
3. See how long it takes for the app to do it

Expected behavior

Renaming a file should be fast and uneventful, whatever you list of previously recorded files is.

Actual behavior

If you have a long list of recordings, renaming a file makes the app lag extremely, even as to trigger a system message saying the app is unresponsive. In my case, it takes up to 18 seconds.

Screenshots/Screen recordings

No response

Additional information

My record folder contains 68 files for a total of 55,8 MB. They are all .m4a files created with VoiceRecorder.
Although when selecting this folder through VoiceRecorder, it only counts and lists 17 files, vhich may constitute a piece of the answer (or may be worth anwther issue entirely).
