Kutheni ndingekakwazi ukuvula fixed DBF ifayile?

Kukho izinto ezintathu ezinokwenzeka kule meko, ngolu hlobo lulandelayo:

1. akho DBF ifayile yenziwe ngesicelo esinye, kodwa ufuna ukuvula ifayile esisigxina kwesinye isicelo, esingahambelaniyo ngokupheleleyo nesokuqala kwaye sibangela iingxaki. Isisombululo kukuseta uguqulelo oluchanekileyo kwibhokisi ye-combo ecaleni ko- “Khetha DBF iza kulungiswa” hlela ibhokisi ngokwesicelo sesibini kwaye emva koko start ukulungisa ifayile kwakhona. Umzekelo, yakho DBF ifayile yenziwe nguClipper kodwa ufuna ukuyivula kwi-dBase III, ngoko kufuneka ubeke "Uguqulelo" kwi "dBase III" kwaye ulungise ifayile kwakhona.
   
2. Yakho ilungisiwe DBF ifayile inkulu kuno 2GB, umda owaziwayo wobungakanani be DBF iifayile, ngoko most DBF izicelo ezihambelanayo azikwazi ukuvula ifayile yakho. Umzekelo, xa usebenzisa iVisual FoxPro ukuvula ifayile enjalo, uya kufumana impazamo ethi "Hayi itafile". Isisombululo kukwenza "Yahlula ifayile xa inkulu kuno ### MB" ukhetho kwi "Options" ithebhu kwaye usete ixabiso elifanelekileyo, elimele libe ngaphantsi kwe-2GB, umzekelo, i-1800MB, njengobukhulu befayile, kwaye wandule ukulungisa eyakho yokuqala DBF ifayile kwakhona. Xa ifayile emiselweyo yemveliso inkulu kunomda, DDBFR izakwenza ifayile entsha eyahlulahlulayo ukulungiselela idatha eseleyo efunyenweyo. Kwaye ukuba ifayile yokwahlula ifikelela kumda kwakhona, ifayile yesibini entsha iya kwenziwa, njalo njalo.
   
3. Ekulungiseni kwakho DBF ifayile, kukho ngaphezu kwe 255 imihlaba kwitheyibhile. Okwangoku most DBF izicelo ezihambelanayo azixhasi itafile enemihlaba engaphezu kwama-255. Umzekelo, xa usebenzisa iVisual FoxPro ukuvula ifayile enjalo, uya kufumana impazamo ethi "Hayi itafile". Isisombululo kukwenza "Yahlula itafile xa kukho ngaphezu kwe ### imihlaba" ukhetho kwi "Options" isithuba kwaye usete ixabiso elifanelekileyo, umzekelo, 255, njengowona manani aphezulu entsimi, kwaye ke ulungise eyakho yoqobo. DBF ifayile kwakhona. Ngoko xa uDDBFI-R ifumanisa ukuba kukho ngaphezu kwama-255 amasimi kwitheyibhile, iya kudala itafile entsha yokwahlula ukulungiselela iindawo eziseleyo. Kwaye ukuba amasimi aseleyo asengaphezu kwama-255 amasimi, itafile yesibini entsha yokwahlula iya kwenziwa, njalo njalo.
