Question

I would like to lock a file on a usb stick so that if you try to acess the file it will ask for a password, i've seen it done on televison but don't know how to do it.

Answer 1

You need Winace. Download and install winace. It works like winzip and will unzip files and handles most type of compressed file. It will not only compress your file - but encrypt it too if that is what you want. You right click a file and just select encrypt and select a password. Quick and easy. You also have the option of encrypting the filename. So be careful! If you encrypt file names - make a list as you do them in a text file using notebook. Then encrypt your text file - but not the file name. You then have a list of the file names and details of what they are in you text file. You can also put passwords in your text file if you use mulitple passwords. You can right click a folder and encypt everything in the folder and all the files also get compressed. but when you unencrypt and uncompress them - they uncompress to different folders. So if you have 100 files in a folder - you encrypt them all - then later want all of the. It unencrypts them and uncompresses them to a 100 different folders. That can be a problem. So you may want to take the 100 files - compress them to one file and then encrypt them. Then copy the encrypted file to your USB stick - then when you unencrypt them you will have one compressed file - uncompress it and it will uncompress all your files to a folder. Winace is shareware and on trial - but works after the time runs out - but with a "nag" screen.

Answer 2

You need to download an encryption program, some can encrypt single files however you are far better off creating an encypted vault folder on the stick.

You can find freeware programs to do this at :

There are quite a few there, it's easier with a vault as you don't have to encrypt each file, just drag and drop it in the vault folder.

Answer 3

If you expect high data security, use an encryption S/W. If simple passwd protection is good enough, zip the file with winzip using the password option so you need to supply the passwd when you want to unzip it.

Answer 4

sure and no. you should use direct hyperlinks to pull the records from different spreadsheets to the interior sight one. as an celebration - on interior sight sheet: A1='[source1.xls]Sheet1'!$A$a million (inspite of records you try to pull) A2='[source2.xls]Sheet1'!$A$2 (be conscious in case you intend on coping and pasting the formulation get rid of $'s) now once you open your new interior sight sheet excel ought to ask you in case you'll favor to replace hyperlinks - elect sure. i trust employing this technique, the different spreadsheets ought to stay unlocked at the same time as your interior sight spreadsheet may have each and each of the as a lot as date info you want. *Please be conscious: this would only paintings if the records you try to pull is continually interior an identical cellular references. reckoning on the quantity of records, this would take a lengthy time period to initially set up, yet will only take seconds later.
