Is there no limit on generating thumbs.db file with size, nor number of files being cached?

Question

I've seen some articles saying thumbs.db file's limit is 349MB

(All the causes of them seem just been corrupted by the way)

I'm wondering is there no limit on generating thumbs.db file with size nor number of files being cached

And if it doesn't, I'm wondering how to make thumbs.db to exceed the limitation

And involved with the question 'number of files being cached',

I've seen somewhere that windows thumbs.db depends on hash values of every single files to verify each files.

I'm actually doubting when the number of file goes too much, it can reach the physical limit of number hash can be generated.

What kind of hash windows thumbs.db use and how many files it can handle once?

Answer 1

Thumbs.db does not have a fixed limit on how many files it can cache. It can cache thumbnails for a large number of files as long as there is enough disk space and system resources available.
