Your calculator comes with APPS, but probably didn't come with programs unless you've downloaded some from the TI site or linked a program from another calculator.

Your APPS or programs cannot be deleted without going through the memory mgt/del screen. In other words, you can't press APPS, arrow down to the APP and hit the delete key and delete your APP.

If for some reason you accidentally delete a TI APP or a program, I think as long as you have registered you calculator with TI, you can download the missing APP or program from their site.

To disable APPS & programs (necessary for some standardized tests). With the calculator off, hold down the left and right arrow keys at the same time then press on. A disable screen will come up and you can choose to disable them. However if you do this you will not be able to use them again until you enable them again.

To enable, link to another calculator and send an app or program from that calculator to yours. This will turn your apps and programs back on.

How to recover permanently deleted Google mails.


Hi
Unfortunately, "permanently deleted" means what it says. Since this is a webmail account your emails are held on a google owned server and not your own computer, therefore you cannot retrieve them by data retrieval (which is often expensive) from your hard drive. Your only option is to contact gmail in some way and see if they have an older backup of their system which they can use to find your missing emails.
Sorry I con't be more optimistic for you.
Cheers

I have lost all my e-mails from 2002 till 2009, can you help retrieve them?


Deleting messagesPrint
1)Gmail lets you delete either an entire conversation or one message from a conversation. Deleted messages are a lot like the stuff in the trash can in your kitchen: eventually, it's all going in the big dumpster outside, but for a little while, you can still rummage through it if you lost something important. Gmail will empty messages from your Trash automatically after 30 days, or you can permanently delete messages yourself.
2)Here's how you can get rid of an entire conversation:
Open the message (or select the checkbox next to it).
Click the Delete button to move the message to Trash.
3)And here's how you'd preserve most of a near-perfect conversation, but forget about a single message:
Open the conversation and find the message in question.
Click the down arrow next to Reply, at the top right of the message pane.
Click Delete this message.
Oh no! I've made a terrible mistake! I want that message back!
4)It's okay. Just after you delete a message, a yellow bar with an Undo link appears at the top of the page. If you click it, your message will be moved from Trash back to its original location. As long as your change of heart occurs within 30 days of deleting the message, you can also retrieve it from Trash by clicking Trash, selecting the message in question, and clicking Move to Inbox. This won't work if you've already permanently deleted the message, though.
No, really. I don't even like having that message in my Trash. Please take it away.
Once a message is in Trash, Gmail will delete it in 30 days, but you're more than welcome to delete it permanently yourself.
5)Click Trash along the left side of any Gmail page. (If you don't see Trash along the left side of your Gmail page, click more above Contacts on the left side of the page.)
Check the box next to the message you'd like to permanently delete.
Click Delete Forever. This time, it's really gone forever.

thanks for rating

My memory stick is write protected...i cant add/delete files.


CHECK if it is not physically protected, a small button/switch might be on the stick!
THEN, try any other flash drive or memmory stick to locate the target problem (memorry stick, or usb port mulfunction or even security/driver issue).

PLUS, there are some programes that might protect flash drives, check if u have any, and uninstall them, and make sure u have deleted ther HIDDEN system files located on the stick!

gd luck.

How to retrieve deleted photos?


Don't worry! Deleting won't make the pictures on a digital camera erase permanently.Those deleted pictures are still stored on the memory card of your camera, they're just invisible or inaccessible.You can recover them with photo recovery software. But once the deleted pictures were overwritten by new data,they are gone for good.
Here I recommend you these software that helped me out:
