Question

I have to delete folder with more than 30000 images.
I have ‘.nomedia’ file inside to prevent scanning all the time.
Trying to delete all files I have to check file name for every file. If I miss this check – ‘.nomedia’ file will be deleted. If this happens before images – this will cause great performance loss.
Any idea how to solve this?

UPDATE:

Does anybody know way to hide images from scanning without use ‘.nomedia’?
I can save files with fake extensions, but I’m not sure is this working.

Update:

Actually test shows me this result: Check for name makes deleting about 50% slower. Problem is not in check code but in system scanning folder 🙁

Answer 1

My solution for moment is:

1. Rename folder with images.
2. Create new folder for images with ‘.nomedia’ file inside.
3. Start background thread to delete old folder.

This way is not faster than previous but allows user to continue work immediately.
Of course with one presumption – user have to know about deleting and cleaning occupied space is not finished for a while.
