Archivers have been around for a couple of decades. Years ago, their primary purpose was to save scarce and expensive hard drive space. Today, when gigabytes are cheap and come in plenty, archivers are used for convenience, out of habit or, in some cases, for efficient compression of certain types of files. For instance, compressed Word documents can be up to 10 times smaller in size than their original uncompressed versions, which is clearly an advantage when sending them by email or directly through an IM client.
RAR and ZIP are probably the most popular archive formats in the world, but there are dozens of other formats that most users haven’t even heard of, so the first encounter with an unknown format may be confusing and disappointing, especially if the archived information has to be extracted right away. To avoid such situations, we recommend installing a multi-format archiver supporting as many formats as possible. A good example of such a program would be PicoZip or ALZip, both supporting extraction from dozens of formats and saving to several popular ones. Both of these tools fully support the ARC format, which was widely used in late 80’s and early 90’s, before ZIP conquered the market. This legacy archive format can sometimes be found in software catalogs, old systems and backup copies, so if you ever come across such a file, don’t worry — the majority of properly designed archiving tools fully support it. Working with ARC archives is no different than working with a regular ZIP, 7Z or RAR file. If you have all of your file associations configured, clicking an ARC file will start a corresponding decompression program. If not, you can drag and drop an ARC file onto a corresponding program or start it first and navigate to the necessary file. Select the files and folders you need unpacked and click the corresponding button to start the process. This is it! As you see, the procedure is absolutely identical to that for all other archive files.
DXF small lines to arcs 1.0 The program converts many small lines in a dxf file which form arcs into arcs. The dxf file will become much smaller and it can be used for a CNC project much easier. The CNC
DXF Splines to Arcs 1.0 Convert B-Spline curves contained in DXF files into arcs. So it will be possible to further process the dxf files and use it with your CNC machine. The program reads existing DXF
