Sometimes, you want to import a batch of files quickly, you can do it by command. write.FileList can be used to import a batch of files into the source table in the *.rqda file. addFilesFromDir can add all files from a directory into *.rqda.

write.FileList(FileList, encoding = .rqda$encoding, con = .rqda$qdacon, ...)

addFilesFromDir(dir, pattern = "*.txt$")
