crash full index index catalog crashes

[fireheart2008]

ok it crashes because of the great number of files or some of the files are problematic
but on a fewer number of files ~700 (sorry to call this few!) it works great

to include more files i thought of some solutions but not sure if they are possible
1. incremental indexing of folders:
to do a full index of folders containing the good files, after this is done i add the folder with problematic files. i'm afraid it will delete the initial full index

2. some way to skip problematic files or at least identify them to fix them or skip them

Is it possible to help provide the following info for further investigation and better advise、
1) Version number of your Foxit PDF Editor;
2) Could you please be more specific on "problematic"? How did you determine the file is problematic? Is it possible to upload one problematic file here for us perform further testing on our side?
3) Could you please use your phone to record how you introduce the problem on your side so we could test per your instructions?
4) Your OS info. (E.g. Win 10, 64-bit)
