I have a weird problem, when I FTP into my zero, I can't locate the:
/data/local/home/.gmenu2x/skins/Default/wallpapers
...folder. It's there in my zero when I choose a wallpaper, but when I try to add more through my FTP program, the folder isn't there...
This is what happened to me.
I'm using Filezilla and as someone in IRC was kind enough to point out, I couldn't see the folder because I didn't select the option to display hidden folders. In Filezilla go the Server on the top of the menu and select "Force showing hidden files" and boom, all the folders with periods in front of them are visible.
The directory for the wallpapers still wasn't there but I created it, put my images there and all was good.
What stumped me was why I couldn't see the default images that came with the Zero but as pcercuei pointed out in this thread
http://boards.dingoonity.org/gcw-help/wallpaper-directory-doesn%27t-seem-to-exist/ , they're built into the rootfs.
