keep in mind, that those 'ini' file entries are DYNAMIC, meaning, they 'jump' not only in their position on the doogiePIM 'Home Page', but also within the >> doogiePIMSettings.ini <<, depending upon which file/ db was used last etc. doogiePIMSettings.ini is always 'in flux', hence be careful with any editing, and make sure you've got a WORKING BACKUP of it, before any 'tinkering'!!
The files mentioned, once on lines 1132 and 2347 (see my post above), are now located on lines 1138 ('mruDoNotes0') and 2352 ('mruDatabases1') 'mru' stands for "most recently used', I guess.
If you run your db from a flash drive, there should be considerations re Drive Allocation LETTER - it could easily be, that that USB drive is at some point "Drive E" and "Drive F" some other time, which would of course be an explanation, why doogiePIM could not locate them - maybe keep an eye on that!
I will keep both, the 'critter' db and 'critter DoNote (both are empty, except for "critter TEST ONLY" - it's the only 'critter' on my laptop, and thus makes global search easy), and occasionally play with them, just to keep an eye on their 'being there'. If I notice anything other than expected with those files/ links to them, I will post that observation here.
Hope this helps.
