Hold down on it and look at the properties.
Yeah I already did that, but it just says location is /data/dalvik-cache. But I'm not familiar enough with sym links to know if the properties will tell me if it is linked or not.
It's my understanding that linking something tricks the system into thinking the file is someplace, when in reality it is someplace else. So, I'm unclear if the file browser is also "tricked"; ie. it thinks the files are at /data/, and shows me as such, but in reality it's on the SD card. Or, if it's showing me the truth.
Am I making sense?
EDIT: I've done some googleing, and I guess what I'm asking is how to tell if a path is absolute, or symbolic. I've found numerous ways in which to figure this out programatically, but I'm not writing a program. I just want to be able to tell this within ES explorer, which might not have the ability to do so. If ES can't do this, is there a terminal command to tell me?
EDIT AGAIN:
To answer part of my own question:
Does the 'properties' dialog in ES File Explorer indicate if a folder is actually a symbolic link, or not? Doesn't look like it. I looked at the 'properties' of both /mnt/sdcard and /sdcard. Both 'properties' dialogs look exactly the same and provided the same information.
So, back to my original question: is there a way to tell if a folder (ie. /data/delvik-cache) is actually on the phone, or a symbolic link to a folder on the ext2 partition on my SD card? any ideas?
