What is this file used primarily for and is it really needed? The reason I asked is that I saw it as being one of more files deleted while chkdsk was fixing my FSX hard drive. It is located in FSX\SETUP\XPackCash Directory. If it is really needed, what are the procedures for fixing it other than reinstall or repair of FSX?wb2002ASUS P5Q SE PLUS/Thermaltake W0106 700W PSUIntel QX6700 Quadcore - 2.66 OC TO 3.2Vista Ultimate 64/CORSAIR XMS2 DHX 4GB (2 x 2GB)2x150GB SATA WD Raptor- No Raid/2x320GB SATA WD SE16- No Raid2x IDE Light-On DVDRW 165H65/BFG GTX2603x SILENX 120X25MM FANS + 2x 10in XCLIO Wind Tunnel Case FansDanger Den Water Cooling/Enermax temp/fan controllerFSX ACC@ 1600/1200 |UTX/ASX/FEX/MTX/ASA/REX

The X-Pack cache is the back-up of all the files that are replaced when the Acceleration pack is installed. These files are preserved so that the user can uninstall the X-Pack and return to his previous installation.There is no particular reason why chkdsk should find that this file is broken, but if so and if it really is no longer in that folder, then simply take the file in the root folder and copy it to the cache folder. Rename it FSX_terrain.cfg so that the Restore function will find it.Best regards.Luis

Thanks for the response and suggestion. This one caught me by surprise - I was unaware of this folder and reason.After thinking about this, since several other files had been affected, I decided to uninstall and reinstall OS and FSX all over again. There are a million things that can go wrong with FSX and nothing I hate more than, flying for a few hours and on final approach, when FSX freezes or crash to desktop.I already had backup of Vista64 clean without FSX installed. Here I go again . . . . . .wb2002
