ConcatXY

ConcatXY is a simple but sophisticated Windows® application for combining multiple XY-pair files into a single file. XY-pair files are ASCII text data files with columns of abscissa/ordinate pairs separated by a separator character (comma, tab, space, and ...). User specifies an abscissa (X) value as zero or base point of data. ConcatXY take the value of ordinate (Y) at the zero or base point as zero and then shift other ordinate values with the same amount and in this way we have a single data set with the common base. Single line comments are allowed in the input files and user can specify comment sign (a single character). XY-pair separator can also be chosen by user.
When user select a directory as ‘Working directory’ all files with the specified target file extension in this directory and its sub-directories will be added to the file list.
