BuildPlus has the ability to import projects from BPI (BuildPlus Import) files, which are turn created via exporting and can also be found in each project's error files folder. Particularly for large batches of imports you may find it helpful to use the command line.
To import a BPI file you need to specify at least the file to import and the BuildRoot to import into.
/importbpi
/importroot
"C:\Program Files\GMCL\DBDOC\Programs\BuildPlus" /importbpi "C:\DBDOC_BUILDS\Project07\Project07.bpi" /importroot "D:\DBDOC_BUILDS"
/importproj
"C:\Program Files\GMCL\DBDOC\Programs\BuildPlus" /importbpi "C:\DBDOC_BUILDS\Project07\Project07.bpi" /importroot "D:\DBDOC_BUILDS" /importproj "Project07_copy01"
/importbatch
For both previous importing examples the CSV file would look, when viewed as plain text, like:
"C:\DBDOC_BUILDS\Project07\Project07.bpi",D:\DBDOC_BUILDS, "C:\DBDOC_BUILDS\Project07\Project07.bpi",D:\DBDOC_BUILDS,Project07_copy01
To import, specify the path to the CSV file.
"C:\Program Files\GMCL\DBDOC\Programs\BuildPlus" /importbatch "C:\DBDOC_BUILDS\Project07\Project07.csv"
