I put TMPFILES = "C:\program files\pprod_vfp\" in CONFIG.FPW but it doesn't work again for one workstation. My app is located on network "G:\producti\calprod\" and the tables are in "G:\gestion\dbase\". The problem appears when a user do a PACK. The table in "G:\gestion\dbase\" is erase from disk during vfp PACK command. Only a xxxxxxxxxx.TMP remains in "G:\producti\calprod\". My question is what are the different reasons a vfp PACK failed? Where vfp need to write on disk to execute a PACK? By the way, all users have permissions to write to the paths specified above.
