always different files on three tries, but always in same folder. so i want to exclude that folder which is not working...

Maybe, but you'll need to work out which switch to use though:

Maybe you can exclude files with pattern matching. See also lha.guide. But first I would check why the error happens and what it means. If there are illegal characters in filenames/directory names you can remove/replace them.

fun fact is: if i try to pack this folder alone, it works 100% without error. only if i pack work partition completely including this folder, then there's an error. and it's different files in every try. first try: work:whd/testdrive2&datadisks/data/scen/rock_roaddata1, 2nd try: rock_roaddata2, 3rd try: rock_roaddata4...

i don't think that "&" is an illegal character, because there are no problems regarding fire&ice...

Do you have enough RAM to be able to create an .LHA archive of a complete partition?

I've noticed before that when creating an archive of say onEscapee I needed loads of RAM as obviously the archive gets temporarily stored in RAM while generating...

i have 62mb fast ram from aca1221, 6.7mb fast ram from aca500plus and 2mb chip ram (1mb onboard + 2*a512 in trapdoor).
so in total i have about ~70mb fast ram. the packed end "product" of my work partition takes ~100mb.
does lha really need this big ram? what if work partition was full (~4gb)? there is no amiga out there capable of 4gb ram...

Ok, just did a quick test and this seems to be how LHA works in relation to RAM when compacting.

I had 32MB of Fast RAM (which showed in DirOpus as 31540K). I then tried LHA'ing a file which was 3629890 Bytes; while this was processing the available free Fast RAM went down to 27302K. That's a difference of 4238K.

The RAM is actually returned once the file from multiple selected has processed.

So if you have large files though; this is when you need lots of RAM.

For example the Genetic Species intro is about 190MB; you would need to have 256GB of Fast RAM or something to be able to LHA up.

When packing the partition, maybe the path is too long for at least one file in that particular folder.
