mysterious Byte increasment with compress - decompress

[Tiemo Hollmann TB]

Hello,

when compressing and decompressing any files with the following statements
(assuming that "it" has the right values)

put compress(URL ("file:" & it)) into URL ("binfile:" & it & ".gz")

put decompress(URL ("binfile:" & it)) into URL ("file:" & item 1 to -2 of
it)

the resulting decompressed file has another number of Bytes as the original
file and in case of a rev stack it is corrupted, when trying to open it.

What am I doing wrong? Probably something with the file - binfile - file,
but I don't see it

Thanks

Tiemo
