Hi there

I wondered whether, if you delete files from say, the internet or other documents, is there record of this on the computer elsewhere? or is it fully deleted?

thanks for your help

Allo Lauraa :thumbsup:
Deleting files on a PC doesn't actually delete the file, only the entry in the FAT (File Allocation Table, the drive's 'index') The contents of that file are still there on the drive and can be re-read with the right software.

Sometimes, depending on the file's physical position on the drive, the deleted file might be overwritten by another file when it's saved, but not always!!!

Security software is available (some free) that will repeatedly overwrite a file with 'rubbish' data so it can't be reconstructed again...

Also, some filenames are stored in the Registry as MRU's (Most Recently Used), a good registry cleaner will find and remove these for you :flowers:

I hope this helps answer your question :trumpet:

If you have some "sensitive" information, that needs to be removed, I suggest a program, like Eraser (Free).
This is one of the security programs WereBo alluded to.
It will overwrite the file with a series of 1's and 0's, effectively "erasing" the file.
You can set it to overwrite a file, using from 1 to 35 passes.
The more passes, the longer it takes, but the more secure the erasure.
I would use a minimum of 3 passes, for sensitive information.
It adds an option to the right click menu, called "Erase".
So when you right click on a file, choose "Erase", instead of "Delete".

When you choose to Erase a file, make sure that's what you want to do, because recovery of the information will not be possible, without the use of some expensive recovery techniques, if then.

I use Eraser habitually for all file "deletions" whether the information may be sensitive or not. As long as you are careful to think about what you delete, there is no problem. An erased, or overwritten file, cannot be retrieved and most likely could never be resurrected even by most professionals, so one must be careful.
Whereof one cannot speak, thereof one should be silent.
