[madguy02]

@sampaiodiego are there plans to support this file format?

[madguy02]

@phongb2b you can probably zip or tar the file and then upload... that should work

[sampaiodiego]

definitely. the error seems it's trying to process it like an image, the fix might be treating is as a regular file

[phongb2b]

@madguy02 yes, it works with zip/rar but our user would like to drag and drop CAD file to RocketChat client.
PS: We could upload/download SQL bak file and it auto convert to .bak.bin file., then we have to change back to .bak

[madguy02]

For the first part regarding autoCAD .dwg support, I will try to submit a PR ASAP.

For the second part of your query, you mean the .bak file are auto converted to .bak.bin?? after download?

[phongb2b]

@madguy02 after we upload SQL xxx.bak file, it auto changes to xxx.bak.bin when completed upload file. We do a hash check that file (after downloaded and change back to xxx.bak) , it is OK.

[madguy02]

Ok, shall look at it once...

Thank your effort
