Patch_Internal re-use this file

[acer20006]

hello all .
im trying to patch client by using old file been set in Patch_Internal from old DB i had , when i copy past the Patch_Internal to a new DB and make the update , Client error appeared , i noticed that file in Patch_Internal was changed or compressed and when i use it with the new BD the SMC compressed it again which lead to bad client <<
my question is there any way to use compressed file in Patch_Internal (old one) in new DB and make update from it with out problem
_ or _
can i uncompressed the file to the normal way that i can read it and use it directly to PK2 file ?

thanks
