IDX file extension is used by index files created by various search tools. Single IDX file contains and index of files or folders located in, for example, a data catalogue.
IDX files can be generated by search function of a given application. They can be quite large, and deleting such file has no effect on the program’s behaviour. However, in many cases a deleted IDX file will be recreated during subsequent indexing process.
Index files are use by applications to speed up file search processes, in database queries and as sorting algoritm subroutines. IDX files are usually found in databases, but many other programs also make use of them.
We hope we helped you solve the problem with the IDX file. If you do not know where you can download the application from our list, click on the link (which is the name of the program) - you will find more information there on the location where to download the secure setup version of the required application.
There can be more reasons which determine that you are not able to open the IDX file (apart from the lack of the proper application installed).
First - the IDX file may be incorrectly associated with the application installed to support it. In this case, you need to change this association by yourself. To do this, right-click on the IDX file that you want to edit, click "Open with" and then select the program from the list that you have installed. After this operation, the problems with opening the IDX file should be solved.
Second - the file you want to open can simply be damaged. Then, the best solution is to find a new version of given file, or download it again from the same source as before (maybe for some reason in the previous session the download of the IDX file has not been completed and it cannot be opened properly).
If you have additional information about the IDX file, we will be grateful if you share it with our users. To do this, use the form here and send us your information on IDX file.
