I use PCManFM 1.3.1 on Ubuntu 20.04
I observed this error when using the Tools / Search files / Properties tab, "file size smaller as" filter:
the resulting file list will also contain files which are 1 byte bigger, hence equal to but not smaller than the value set in the search. The same is true for the other direction: a search for files bigger than x bytes will also find such with exactly x bytes.
How to reproduce: run a search for files with a size in bytes on a folder which also contains files 1 byte smaller (or bigger) than those expected to be found. The search result will also contain the files which match the given size in bytes instead of only those smaller (or bigger).
