I was finding way to hide or lock files or folders on my Samsung
phone. Windows hidden files are shown in file manager so hide option
from java apps was no more useful. Even hiding with system attribute
do not work(attrib +h +s folder). so i stopped trying Nokia tricks. I
tried my old trick of file type altering which worked-
Trick1:
Using FM(file manager) in UC Browser,Rename filename to "anything.X" >
file locked. rename back to original to open.
X=fake_extension(.jar,.pdf)
Later i found one more-
Trick2: remove all after dot in filename. - rename file to
"anything."(notice dot after filename). Now rename back is failed. To
unlock, copy file to another dir with uc fm then rename.
Later i tried some slightly diff logic, inserted ALT+160 Char after
extensn to preserve original extnsn.
After playing wid uc fm i found something useful-
Trick3: use uc fm to rename folder. Now folder is shown empty by
inbuilt File manager(FM). FM can't delete folder. Rename back folder
to its original name with any fm to unlock.
but... Restarting phone/removing mmc/using pc connection brings hidden
content back.
Some slightly diff idea are-
rather than renaming same folder create another folder with original
name. now files are invisible to fm. and undeletable to uc fm.
Trick1 alters program associated with file and makes file unrecognisable.
Trick2 works due to internal fm(FM API handler) neglect dot in
filename. It sends "anything" to uc fm. but actual filename is
"anything.". This rejects renaming un-existed file(and Rename failed).
Trick3 has its root at the system file named SThumbDB.tdb in mmc. It
stores handles(or paths) of all directories and files. Renaming folder
with uc fm do not update SThumbDB.tdb hence losses handle to hidden
content.
Trick4: It is very tedious trick to apply. But works in Nokia Phone as well.
Folder Named CON, AUX, PRN could not be read by Phone. So data is safe in those folders. Use Linux OS via USB Mass Storage to create such folders and keep data there.
