DMAP Spreadsheet Format | Alan Morton | Spreadsheet Files |
The NAM file extension is an acronym for dmapp, which stands for Database Map (DMAP) file format. It is a proprietary file format used on desktop computers and servers running Windows operating systems. The NAM file type is a spreadsheet-like file, mainly used by businesses for tracking large sets of data over long periods of time. It contains data in table form, with rows and columns organized for fast retrieval. The tables are saved in the standard DBMS (Database Management System) format for easy manipulation with database query languages such as SQL.
The NAM file extension can be viewed, edited, and printed using the appropriate software, such as MS Excel or a similar program. It is often used to store complex financial data in a highly structured format, as well as to store customer information or demographic data. When working with NAM files, users should pay attention to the structure of the data in order to maintain accurate results and present it optimally.
Similar Types of File Extensions
Similar file extensions to the DMAP spreadsheet format include .dbf, .xls, .xlsx, .tab, and .csv.
Programs for WINDOWS system
After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .NAM) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .NAM extension.
When choosing the software we can select the system to use this software every time.
Remember!
Using it for the first time it is good to check whether the .NAM file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .NAM extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .NAM extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .NAM file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .NAM file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .NAM file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .NAM file) will be extended to the maximum.
It is also good to check
- if the .NAM file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
