Code: Select all
UseLZMAPacker()
; Create the packed file
If CreatePack(0, "mycompressedfiles2.7z")
; add your files
AddPackFile(0, "text_over_4_gb_size.txt", "text_over_4_gb_size.txt")
ClosePack(0)
EndIf
text_over_4_gb_size.txt size is 4 405 088 234 bytes
The result is small size archive with a packed piece of text file
I use demo version of PB 5.72

Is a limit of LZMA
The bigger the dictionary, the better the compression ratio usually is, but dictionaries bigger than the uncompressed data are waste of RAM. Typical dictionary size is from 64 KiB to 64 MiB. The minimum is 4 KiB. The maximum for compression is currently 1.5 GiB.
