To convert a ZPAQ archive to a self extracting archive:
|
|
|
|
+On Windows:
|
|
+
|
|
copy/b zpsfx.exe+zpsfx.tag+archive.zpaq archive.exe
|
|
|
|
+On FreeBSD(the choice of archive name is discretionary):
|
|
+
|
|
+ cat zpsfx zpsfx.tag archive.zpaq > archive.sfx
|
|
+
|
|
zpsfx.tag is a 13 byte file used to mark the start of the compressed data
|
|
that is appended. Alternatively, zpaq with the "t" modifier will append
|
|
the same tag ("a" appends).
|
|
|
|
+On Windows:
|
|
+
|
|
copy zpsfx.exe archive.exe
|
|
zpaq ta archive.exe files...
|
|
|
|
+On FreeBSD:
|
|
+
|
|
+ cp zpsfx archive.sfx
|
|
+ zpaq ta archive.sfx files...

To extract:

archive.exe

+On FreeBSD:

|

|
|
+ archive.sfx

The program reads itself and decompresses the appended archive.
