Check the intended environment first
Ask which device and application will display the presentation. Also establish whether external storage is allowed at all. Bringing a USB drive does not solve anything if the organisation prohibits connecting one. Use only media and procedures approved by your own organisation. A backup must not bypass workplace protections. If the host specifies another transfer method, prepare it in advance rather than negotiating it at the meeting table.
Store one clearly identifiable version
Save the final version with an understandable name and date. Avoid several files called final, new-final and really-final in the same visible folder. Where useful, add an appropriate second format that preserves the essential content without elaborate effects. Check that images, media and necessary fonts appear correctly in the intended environment. A file that opens is not automatically fully usable. The actual sequence of the demonstration is what matters.
Rehearse once without internet
Test the copy offline on an appropriate authorised device. Do not stop at opening the first slide; check important transitions and embedded material. If videos or other elements require separate files, keep their relationship clear. Prepare a simple explanation or suitable still image if a special effect fails. The drive should provide a practical fallback rather than merely move the same untested dependency to another storage location.
Handle the medium and content deliberately
Carry the drive in a fixed place and do not leave it connected to someone else's device after the meeting. Bring only the data required for the task. Confidential material needs the protection process specified by your organisation. After travelling, label or remove superseded versions according to the applicable requirements. The backup can then prevent a failure without accidentally returning later as the supposedly current presentation.
