You can hide or display file extensions in Astro for individual or all folders.
Remember that all folders setting doesn’t override the single folder setting.
With that said, let’s see both.
Tap the three vertical lines at the top left.
Click on “Settings” in the menu.
Tap the “Set Default View Settings” option.
Check (to show) or uncheck (to hide) “Show file extensions.”
Note: If the above settings do not work in the folder, follow the steps above (1 to 3) and hit the “Clear” button beside “Clear Directory Options.” Remember that this will clear custom directory settings.
Open the folder.
Tap the three vertical dots at the top right.
Click on the “View Settings” option in the menu.
Navigate to the “Advanced” tab.
Check (to show) or uncheck (to hide) the “Show file extensions” option.
Press the “OK” button at the bottom.
