Preserving and copying user editable databases


Whenever you edit (add, change or delete) an item in any of the databases the database file is resaved and thus it is given a new 'date stamp'. There are literally thousands of user editable databases within the complete Mistral suite of programs so the best way of finding a database that you wish to preserve and copy across to a new program installation is to re-enter the database and make another edit. If you don't really want to alter anything then simply add something like a space at the end of a text description or maybe change capitalisation of just one word (Eg change polyurethane to Polyurethane). Then using Windows Explorer (with file date attributes switched on. Refer to MS Windows help files if not sure how to do this) look in the folder where your Mistral programs are stored and identify ALL those files that have a date and time stamp corresponding to the time you made the data edit. Copy those files into another folder somewhere or even onto a CD-ROM or to a USB data storage key, then AFTER re-installing your programs, copy the saved files into the program folder. By default, the normal folder that Mistral uses for all files (except for graphical images) is C:\Program Files\Mistral.

IMPORTANT

Some databases comprise more than one (sometimes two and sometimes three) separate files. All will have common 'stem' names but different 'extensions'. Eg AIRWIND.DAT, AIRWIND.IDX and AIRWIND.BLB (sometimes shown as airwind.dat, airwind.idx and airwind.blb. It is ESSENTIAL that these are always copied across as matched sets as they are dynamically linked, inter-active database files and if mismatched (I.e. have different date stamps and mismatched content then all hell will break loose within the Mistral program and it will only produce gobbledy-gook results.

Don't be alarmed if when editing a database within say Coldwind if this makes changes to database files with names that relate to other programs such as Airwind for example. This is normal as these database files are sometimes shared amongst other programs
