New user question - Re: Boot up options

[BudgieUK]

Hi Everyone.... first post here, but I have been "lurking" for a while. (the info here has been so useful)

I'm looking for a little advice..... I have an O2 XDA Exec (1 week old), and when I first had it, I started it with the personal boot up profile.... it was tooooo slow, and I saw mention on here of the "Corporate" setting (using a password).... I found there is a menu option to switch from one mode to the other, and I have done this, but I am now thinking.... should I have hard reset the XDA rather than switching modes?
Do I have a load of "stuff" in memory that I dont need?

In case its important:
Rom:1.13.82 WWE
Radio: 1.04.02
Ext ROM: 1.13.188 WWE

I've also just noticed a load of files in the Windows directory on the XDA that I do not recognise... with DSM and RGU extensions.... the file names are really long like... e3d5a498-ccb1-413acs-fa34cdc-b4b3bba.rgu - can I delete them?
There are also about 14 files called cab1_OK.txt up to cab14_OK.txt... as these are just txt files, I assume I can delete these safely???

Sorry for being such a dunce... but I'm trying to understand what is and isn't OK on the machine.... I'm not sure I understand the difference between program and storage memory (and persistent storage).... if anyone can point me at something that helps me understand, I'd be really grateful.

Can anyone offer me guidance here please?
