When I viewed its "file", I saw import and export list, what are they?
Solution
Boxoft TIFF Merge and Split () support Export list allows you to save current all your operations contains where TIFF files are, their seqences, once you have exported them into a folder, this software will save this record as a TXT file to record all your activity. somewhen you can use "import list" functionality to import this TXT, and then you will see all the same TIFF files and sequence on its interface last time.
