更新日志
What’s new in 7-Zip 24.09:
The default dictionary size values for LZMA/LZMA2 compression methods were increased:
dictionary size compression level
v24.08 v24.09 v24.09
32-bit 64-bit
8 MB 16 MB 16 MB -mx4
16 MB 32 MB 32 MB -mx5 : Normal
32 MB 64 MB 64 MB -mx
32 MB 64 MB 128 MB -mx7 : Maximum
64 MB 64 MB 256 MB -mx8
64 MB 64 MB 256 MB -mx9 : Ultra
The default dictionary size values for 32-bit versions of LZMA/LZMA2 don’t exceed 64 MB.
– 7-Zip now can calculate the following hash checksums: SHA-512, SHA-384, SHA3-256 and MD5.
– APM and HFS support was improved.
– If an archive update operation uses a temporary archive folder and the archive is moved to the destination folder, 7-Zip shows the progress of moving the archive file, as this operation can take a long time if the archive is large.
– The bug was fixed: 7-Zip File Manager didn’t propagate Zone.Identifier stream for extracted files from nested archives (if there is open archive inside another open archive).
– Some bugs were fixed.
