Not really advisable changing the file type to attach the file as this can at times corrupt the data contained in it.
Upload any minidump or memory.dmp files, zipped to reduce size. Give the zip file you are uploading a unique name (e.g. forumusername-mem-dump.zip, etc), so they can identify it. It might not be a bad idea to create a text file (readme.txt) with any relevant information,
avast topic URL, user name, etc. etc. in the zip file.
- Memory dump locations, Mini Dump files in, C:\Windows\Minidump\ - Full Kernel dump file, C:\windows\memory.dmp
Upload the zip file to the ftp server
ftp://ftp.avast.com/incoming:
- Using Internet Explorer, Connect to the link and drag the file into the Right pane and drop it, that starts the upload, you don't have read access to this folder.
Or
- Upload it using the Run command-line in Windows: Windows Key + R (to get the run box), copy and paste this explorer ftp://ftp.avast.com/incoming and drag the file into the window, from another explorer window.
