Well ,
Let me explain
I do not know If the poster does actually knows this !
this solution was placed in HTC desire thread , which simply instructed to do the same
but with no additional info
If you study droid , When droid places app to sd card , it actually encrypts the app and places it in the .android_secure folder ...
This folder is mounted at the system start in "secure"
I.e, now /sdcard/.android_secure = /mnt/secure
.asec is a kind of encrypted file that Android creates! this can only be decoded by the same Device
not even another device can decode it ! that is the best part
btw it stands for [ android secure ]
This file , i mean "smdl2tmp1" is a temporary file created which follows the above principals !!
and as the name suggests its a Temporary file ! hence can be deleted as per u wish !!
infact another way to do the same stuff is like ,
remove the same file from /sdcard/.android_secure folder !!
lol...nothing of my interest there....
I already know these things
The interesting thing is, why smdl2temp1.asec only?
