So I have X-Cart version 4.0.15 and I I went to the admin >> patch/upgrade page and tried to apply the first patch, the diff file, which in the X-Cart .tgz file was called DIFF_USPS_40x.txt which got a ton of failure flags colored red. I tried renaming the file mod_USPS.php but it still gave me a bunch of red flags:

---
Status legend:
OK - file ready to patch,
checksum error - patch contents is corrupted,
non-writable - please give those files a write permissions,
not a file - the target is not a file,
not exists - file is missing,
could not patch - patch cannot be applied to this file automatically because it was significantly modified, the patch for this file should be applied manually,
already patched - file was already patched.



Note:
Files which are not exists and already patched will be ignored.
----


So... does that mean that the patch isn't necessary? Would it be more effective to just FTP something with Filezilla?

I haven't tried the SQL_USPS_40x.txt file yet. I don't even know if I have to.

Any help? Thanks.
