Merge may refer to any of the following:
1. To merge is to take two or more groups of data and combine them into a single unified set. Generic merging (as with the MS-DOS copy command) takes one or more files and combines them into one file. More advanced merging commands and programs are capable of only merging data that is new or updated to a file.
2. In Microsoft Excel a Merged cell is a cell with one more cell that is combined into one cell. When cells with multiple values are merged, the upper-left most cell will be the data of the merged cell.
3. With revision control, merged is when two or more files that were combined into one final version.
4. With businesses, merging is a description of two companies that combine to become one company.
