PAR file extension is used by Parchive volume files. PAR file contains marked sequence of bytes generated based on the data archive, which allows data recovery in case of loss or data corruption.
Files with .CATPART extension contain 3D CAD/CAM/CAE model parts and structured data associated with them. CATPART files are saved in a proprietary format developed by CATIA. CATPART files constitute a larger project or a functional element of such project created using CATIA V5.
After converting the file to the new format, you will be able to use other programs to support it. Keep in mind, however, that the PAR file after converting to CATPART may differ slightly from the original. The most important information should be kept, but if you want the file after conversion from PAR to CATPART to be the same, you have to do this carefully and choose the proper application from the list below.
There is no guarantee, of course, that the conversion will come up to all your expectations, but it will certainly help you. If, after all, the effect of converting PAR to CATPART does not meet your expectations, you can simply try to find on the Internet a different version of your file in PAR format, properly converted to a CATPART file by someone else. If this fails, use the information provided in the further part of the website.
If after converting the file PAR the desired result was not achieved, you can try to change the format of PAR file to other than CATPART. On our website you will find more information on the following conversion options
Unfortunately, if after performing the two previously described steps (trying to find your PAR file converted by someone else, and the attempt to convert it to CATPART on your own) you still have a problem with your file, then there are only a few solutions left. You can once again try to find and install an application that can open the PAR file in its original format (without conversion to CATPART file). Such a solution will be difficult to implement, but it certainly will give the best result.
