File with .001 extension contains a part of data archive created using a file archiving software. 001 file can use compression. 001 is a generic suffix used by many archive-splitting tools, which may support various compression methods.
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 001 file after converting to 7ZIP may differ slightly from the original. The most important information should be kept, but if you want the file after conversion from 001 to 7ZIP 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 001 to 7ZIP does not meet your expectations, you can simply try to find on the Internet a different version of your file in 001 format, properly converted to a 7ZIP file by someone else. If this fails, use the information provided in the further part of the website.
If after converting the file 001 the desired result was not achieved, you can try to change the format of 001 file to other than 7ZIP. 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 001 file converted by someone else, and the attempt to convert it to 7ZIP 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 001 file in its original format (without conversion to 7ZIP file). Such a solution will be difficult to implement, but it certainly will give the best result.
