How I delete a file?

I saved it with display.save() if that matters… And I want to allow the user to delete it (I am doing a album of sorts in my app). [import]uid: 142895 topic_id: 27700 reply_id: 327700[/import]

You would use os.remove in combination with system.pathForFile

Hope this helps [import]uid: 84637 topic_id: 27700 reply_id: 112341[/import]

Hello!

It ALMOST worked…

I am getting permission denied…

I am deleting a image file, thus I guess I need to ensure it is unloaded first?

I am right now using removeSelf() and then using the pointer to something else, and the delete is triggered by a timer with 500ms.

But this is seemly not sufficient… [import]uid: 142895 topic_id: 27700 reply_id: 112541[/import]

What platform is giving you permission denied? [import]uid: 84637 topic_id: 27700 reply_id: 112558[/import]

Windows.

Android and iOS are targets, but I do not own a Mac or iOS yet, and did not tested yet on Android… [import]uid: 142895 topic_id: 27700 reply_id: 112560[/import]

I was having a similar issue - at least on Win7 & Corona simulator. It appears that there are several apis that do not complete before they return to your code - and I think that image:removeSelf is one. I created a closure that did the os.remove and used timer.performWithDelay to execute the closure after two frames (70ms) to give image:removeSelf time to complete. Worked like a charm (at least one the simulator - have not attempted on devices yet). [import]uid: 117477 topic_id: 27700 reply_id: 115944[/import]
