If you have bigger files to upload you may choose from one of the following proceedings:
- Split your files (recommended) using a tool like e.g. 7zip (recommended, open source), mp3splt (open source) or mp3 splitter & joiner (shareware). There are more tools around, these are the ones I am happy with.
- Reduce your files by a) converting wav to mp3 or b) reducing quality. The bit rate needn´t exceed 128kbps and there is no effect at all (except an increase in file size) in converting a file to a higher bitrate than the original.
- Upload your file to an external hoster that offers good conditions for free users and link to it in your message.
- Or ask for assistance and you will be helped out.
If you see a message talking about uploaded files but without an attachment, the files have been archived already.
Depending on the uploaders´activities, files are kept in the forum between 3 and 6 months usually.
