The only way I know how is to either merge them with another, clean them, or manually change them in Wyre mash. I'm wondering if there's a simpler way, I basically want to permenently change the timestamp of some ESP to a few years back so they dont screw up my load order.

Wrye Mash lets you redate an esp to whatever date you want.

I know but is it able to do so permenently, so that the date remains even if I uninstall?

I don't know, I find WM simple to use (ninja'd by Pluto), but you might also be able to finesse things using mlox user load order. However, I've only used that in one or two occasions where there was a mod rule had not been added yet.

Filetouch ( http://www.wintestgear.com/products/FileTouch/FileTouch.html ) is a windows program that does this. Just download - unzip and run filetouch.exe - add the files you want to change and put in the date you want it changed to and press touch dates and it will change them to the date you entered. ( works in windows or Dos command line ) Says windows XP but I still use it in Win7 64 bit.

The changes will stick if you select lock load times. Right click on the top bar in the mods tab and select that option.

Is that something others would benefit from? Worth posting it in the http://www.gamesas.com/topic/1487854-relz-mlox-anolyze-and-sort-your-load-order/?
