Am thinking of trying FDISR, & ShadowProtect, as some here have mentioned. a) Have about 33GB left on C drive; I could undertake the Herculean task of shoveling out the Augean stables and free up more of C drive, if it's considered best for FDISR in particular - the more room the better, for FDISR? Have about 20GB left on E and can/will clean that out too, as one can store FDISR archives on another drive, I think? b) Can one long after the fact, partition the C drive? IF that is a good idea, what Part. Mgr. might you recommend? OR, is that a task one should carry out at the start, with a new drive? Haven't hitherto gone down that road, so I'm not up on the why/when/how of it. c) From what I've read thus far, one should be "prudent" in the use of 1) Perfect Disk; - have D'l that fix if needed, as mentioned here, 2) shut off DCS app PG in order to move/copy/del some files of FDISR, 3) and also to be hesitant in use of registry cleaners. (I do have one ver of JV16 PTools where in it does Reg. backups, & one can Ignore file/s such as those belonging to FDISR as mentioned on this forum). I know part of this lies in how well an app "takes to" your PC or not, to a point. Does the above "roughly" cover the bases, OR, are there other known apps (esp. security apps), that may collide with FDISR and/or ShadowProtect? Any other thoughts, in general, are most welcome.
