For example, if you specified D:\Historian\DATA\Circular as the circular data folder, the CSV data import folder is D:\Historian\DATA\DataImport,. Important: If you leave the data import path at the default location (on the drive hosting the circular data folder), placing large CSV files in a data import folder may prompt the AVEVA Historian disk management subsystem to immediately start moving or deleting history blocks to maintain the configured amount of required free space on the disk. It is highly recommended to change the data import folder to a different drive than your circular storage. The different import folders are described in the following table: Import Folder Description \DataImport Used for normal CSV import files. \FastLoad Used for "fast load" CSV import files. Files in this folder are processed one at a time, in the order that they appear in Windows Explorer as you are viewing the folder contents. \Manual Used by MDAS for tags. If the amount of data spans multiple 64 KB chunks, files are collected in the \Support subdirectory until all of the data is received. The files are then copied to the \Manual folder for inclusion into history.
