Has anyone written LFS substitute code for WP?

CoronaCards (Corona in native apps) CoronaCards for WP8
#1

Hi all,

One of my apps that I’m porting to windows phone uses the lfs module which is not supported on windows phone. Has anybody written code I could reuse that deals with this? I could write my own, but if somebody has already done it and is willing to share I’d rather just reuse and not spend the time.

Thanks!

Well I implemented the two methods I needed for the file system and put it in a bridge class. Posting here in case anyone wants it:
