How many files can be uploaded using input in HTML?

problem description

I built a small website using flask as the web framework. In the website, I realized the function of uploading files based on bootstrap-fileinput. When uploading files, I found that I could only upload up to 1212 files, but my need was to be able to upload tens of thousands of pictures at a time.

the environmental background of the problems and what methods you have tried

in order to achieve upload without refresh, I use the form of form+iframe to point the target of form to iframe.
at first I thought it was a problem with the bootstrap-fileinput module, but after looking at its code, I found that its initialization parameters do not limit the number of files uploaded by default. At the same time, I have added a native HTML input element to the page, and set type to file, to find that the result is the same.

HTML Code:

$("-sharpfile_upload").fileinput({
    showPreview: false,
    showUpload:fasle,
    showRemove:true,
    maxFileCount:0        // 0
});

I would like to ask you how to upload tens of thousands of pictures or files.

you can take a look at this discussion

has something to do with browser, operating system, file name and size.

generally speaking, the total file name length of 32k is about 12000016000 files
