(6.51) internal zip doesn't work on big file

[sorex]

Hello,

I just tried to ZIP a Live State Recovery file of 5Gb with the internal zip routines (alt-F5), all it gives is a "Can't open/access file"-error

is there a limit for internal zipping of files?

[ado]

Which OS are you using? There is limitation on Win98

[sorex]

It's on Windows 2003 Server Standard Edition

the exact error is...

[Error creating zip!]
Cannot read file!

[ado]

Whuups Live recovery... isn't it possible that Windows has locked that file? Try to open it using F3...just if it is possilbe

[sorex]

thought the same thing but it's not being locked, I can view/copy/winzip the file without any problem

[sorex]

apparently it's some sort of bug, when I try to zip a 2.xGb file on my XP Pro SP2 machine the same error appears

AFAIR there is a only 2GB limitation (compatibility reasons) for zipping with internal-TCmd-zip.
For unzipping there is no such limit (?)

There is a limitation of 4 gig, when using Fat32(edit: for extraction) instead of NTFS.
Maybe its that

[sorex]

ok then it's a TC ZIP limitation, it's both NTFS filesystem otherwise I wouldn't be able to have that 5Gb file

maybe you should either

-get rid of the limitation
-give a "filesize beyond internal zip limit"-error instead of the error I got?

The TC ZIP packer has the following limitations:
1. The packed files may not be larger than 2 GB
2. The resulting archive may not be larger than2 GB

The TC ZIP unpacker has the following limitations:
The archive may not be larger than 2 GB, although the files in it may be larger than 2 GB each. This limitation will be removed in the next version of TC (6.52 probably).

The restrictions in the packer are there because the original ZIP standard didn't support larger files. I find it a bit risky to change the zip packer now, it has been working very well for many years, and I don't want to risk to break it.

No risk, no fun...
