.arh File Extension

Developer: Siemens
File type: ProTool Compressed Project File
You're here because you have a file that has a file extension ending in .arh. Files with the file extension .arh can only be launched by certain applications. It's possible that .arh files are data files rather than documents or media, which means they're not meant to be viewed at all.

what is a .arh file?

The ARH extension is used as an output file format of the ProTool software, and files appended with the .arh extension are also classified as compressed data files. ARH files created with ProTool is integrated with file compression specifications which can significantly reduce the size of project output files developed using ProTool, which are appended with the .pdb extension. Siemens developed the ProTool software as an application for configuring the settings of specific machine processes. This application can also be used to track and monitor elements included in these machine processes. The data of these compressed files in the .arh format includes these configuration and tracking settings, and this data is accessed by the ProTool software whenever a user opens and edits the compressed file with this application. The ProTool application can be installed by users of Microsoft Windows-based systems, to access the features available in this software and to start creating PDB projects that can also be compressed in the ARH format using the ProTool program.

how to open a .arh file?

Launch a .arh file, or any other file on your PC, by double-clicking it. If your file associations are set up correctly, the application that's meant to open your .arh file will open it.

ProTool is a configuration software package for the SIMATICHMI family as it uses the same configuration software to configure all the devices in the family. It is a Windows application used in Windows 95, Windows 98 and Windows NT. It creates object-oriented, symbol-based projects without the need of having programming knowledge. The editors that are provided in the software can be used simultaneously, different projects may be opened, even from different devices, and data can be transferred through the clipboard from one project to another. It can be integrated in the SIMATIC STEP 7 configuration software which allows selecting of STEP 7 symbols and data blocks as tags in ProTool. This eliminates the possibility of making errors in entering the same data several times.The ProTool package contains drivers for PLCs such a Siemens PLCs, SIMATIC S5m SIMATIC S7, SIMATIC 500/505 and PLCs of other manufacturers like Allen-Bradley DF1, Allen-Bradley DH485, GE Fanuc, MITSUBISHI FX, Modicon Modbus, OMRON (Link/Multilink), Telemecanique TSX Adjust, and Telemecanique Uni-Telway.

a word of warning

Be careful not to rename the extension on .arh files, or any other files. This will not change the file type. Only special conversion software can change a file from one file type to another.

what is a file extension?

A file extension is the set of three or four characters at the end of a filename; in this case, .arh. File extensions tell you what type of file it is, and tell Windows what programs can open it. Windows often associates a default program to each file extension, so that when you double-click the file, the program launches automatically. When that program is no longer on your PC, you can sometimes get an error when you try to open the associated file.
