Why does Cloudinary reject the file format of some files I'm uploading?

Many Cloudinary features are focused on image, video, and audio files but in general, it's possible to upload, manage, and deliver any file type.

However, there are some files that can't be used with Cloudinary. This is to protect our service and users from file formats which may be potentially harmful, such as executable files, or formats that may be used to distribute malware.

The following file extensions are rejected by default:

action, apk, app, bat, bin, cmd, com, command, cpl, csh, exe, gadget, inf1, ins, inx, ipa, isu, job, jse, ksh, lnk, msc, msi, msp, mst, osx, out, paf, pif, prg, ps1, reg, rgs, run, sct, shb, shs, u3p, vb, vbe, vbs, vbscript, workflow, ws, wsf
