UU (Uuencoded File) is a file type used to make binary data more suitable for transport through mail applications and plain text protocols. It was initially created by Mark Horton at the University of California, Berkeley, during the early 1980s as an alternative to the BinHex binary-to-ASCII encoding scheme used in Apple Mac OS. UU encoded files are typically denoted with the .UUE extension, but other formats that support text-based email transfers may include .B64, .XXE, and .ENC.
UUencoding Conversion Process
The UU encoding process converts non-textual data like images or executables into seven bit ASCII characters since many mail servers do not allow users to send non-textual data. The process works in four steps. First, the data is divided into groups of three 8-bit bytes. Then each group is converted into four 6-bit pieces. Following that, each piece is mapped to a character defined within the printable range of ASCII characters and most notably, excludes certain control characters such as column separators. Finally, the entire sequence of encoded characters is wrapped in a header line and then sent via email.
Similar File Extensions
There are a number of similar file extensions including Mobile Atlas Creator Atlas Format ( .MAP), Metastock Data File ( .MST), EBCDIC File ( .CPT) and Forex Strategy Builder Database ( .FSB) files.
Programs for MAC system
After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .UU) 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 .UU 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 .UU 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 .UU 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 .UU extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .UU file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .UU 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 .UU file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .UU file) will be extended to the maximum.
It is also good to check
- if the .UU file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
