I've just done a reformat, my machine works a lot better now I've cleaned out all my rubbish that i'd collected over the last year or so. the way i did it was;. .1) All my personal stuff, letters , spreadsheets, dowloaded programme files, etc, went into seperate folders , all stored within 'My Documents' though. This way i only had to copy one folder.. .2) I located the Calendar file thet contained all my appointments etc. I simply pasted it over the blank one after the reformat . It worked.. .3) I used a programme called 'Express Assist' to back up all my Internet Explorer,Outlook,outlook express,folders, settings, e-mails, favorites, etc. It worked.. . It was a bit of a pain in that I had to remove all my added Hardware and return the computer to factory condition, before the 'rebuild' , however i like messing with my machine- it's part of the hobby, imho.. . One thing I did find when re pasting all of my files, etc. I have 2 drives in my machine,a DVD drive, and a CD-RW, I found that the files would not work when put back on the machine via the DVD drive even though I could see them/use them of the CD (DISASTER!). I tried again using the CD-RW Drive (which had been used to make the copies) and hey presto everything pasted and worked . Spooky. The computer goes like a train now (a Japanese Train !)HTH.
