HUG Celebrated its 35th Anniversary in January 2018


We are the Oldest Computer Club in South-Central Pennsylvania and have been meeting continously since 1983



Meeting Schedule - Spring 2018




Meetings & Workshops

Date & Time - The date for our Weekday Meeting & Workshop is the Third Thursday of each month from 6:30 PM until 9:00 PM. The date for our Weekend Meeting & Workshop is the Third Sunday of each month from 2:00 PM until 4:00 PM.

All meeting ending times are, of course, dependent upon the number and complexity of the computer problems brought to the workshop. We can always stay later if we need to. We believe that this schedule accommodates most members. Let us know your opinion.

Agenda - If you have a computer question or problem then bring it to our workshop to receive individual assistance. This service is free to all members in good standing.

Attendance - Your attendance is always appreciated. Please arrange to attend a meeting & workshop whenever possible. You are also encouraged to bring a guest. Your guest may want to join and take advantage of the technical assistance that HUG offers.

Important - If you are coming with a broken computer then you should contact us in advance so that we expect you. Be sure to ask what equipment you need to bring along - your monitor? keyboard? mouse? printer? operating system disks? application program disks?

Please plan to arrive early with your broken computer. If you don't, you may find all available troubleshooters are busy assisting other members for the entire meeting.


Location - Our meeting location is at LifePoint Church, on 7733 Hillcrest Avenue, Harrisburg, PA 17112. It's just off Allentown Boulevard, 6/10 of a mile west of Route 39, next to a Fulton Bank.

We use the downstairs, multi-purpose room. A big advantage of meeting in the downstairs multi-purpose room is that members can back their cars right up to the door to unload/load equipment.

Another advantage is that we have a nearly limitless amount of worktables and space. Both wired and wireless Internet access are also available.

Detailed directions and a map to the meeting location are available on the church's web site home page at LifePointPA.org.

Alternately, you can use MapQuest directions or our own HUG Map for directions to get to our HUG Meetings and Workshops.



Are Your HUG Membership Dues Paid Up?

Technical Tips - File Extensions

The following is a review and summary of FileInfo. Please visit their site at https://fileinfo.com for much more information about file extensions.

What is a file extension? File with Extension

A file extension, or filename extension, is the suffix at the end of a filename, which indicates what kind of file it is. For example, you can tell that the file displayed on the left is a rich text file because of the ".rtf" extension. Similarly, " readme.txt " is a plain text document, " computer.jpg " is a JPEG image file, and " document.docx " is a Microsoft Word document. It is helpful to learn the most common file extensions, since you will be able to identify common file types.

While most file extensions consist of three characters (.PDF), some have fewer (.H, .DB, .PS) and others have more (.HTML, .TORRENT, .TAX2016). When you double-click a file, your computer uses the file extension to determine what program should open it. The connection between a file extension and the default program that opens it is called a file association . You can change file associations in both Windows and macOS .

If you manually change a file's extension, it may alter what program your computer uses to open the file. Therefore, you should be careful when changing file extensions. If you assign an invalid file extension to a certain file, your computer may not be able to open it. For example, if you change a ".txt" file to a ".jpg" file, it will open in an image viewing application rather than a text editor when you double-click it. The image viewer will most likely produce an error saying it does not recognize the file.

Because such a large number of software programs exist, there are tens of thousands of file extensions. While it is helpful to know the most commonly used file extensions, it is not practical to try and remember them all. Therefore, whenever you come across a file extension you don't recognize, visit FileInfo.com to find out what kind of file it is and what programs can open the file.


FileInfo - The File Extensions Database

About FileInfo

FileInfo contains a searchable database of over 10,000 file extensions with detailed information about the associated file types. You can look up information about unknown file types and find programs that open the files.

Since 2005, the FileInfo team has worked with developers, large and small, to create a central file extensions registry. FileInfo.com has become the authoritative website where developers can submit new file extensions and provide information about file types. If you are a developer, you can easily register your file extensions with them.

Software

FileInfo now contains descriptions and reviews of hundreds of software programs as well. Visit the Software section to browse a list of programs. Each software page includes a review of the application, a list of program features, and a list of supported file types.

Using FileInfo

You can look up file extensions and software programs using the search box on the top of each page. You can also use the Advanced Search feature to search the entire website. If you have file-related questions, there is a good chance you'll find the answer in their Help Center.
