The '''Interim File System''' (usually referred to by the acronym, '''IFS''') was an early [[data network]]ing [[server]] providing a number of services, principally remote [[secondary storage]] access, using the [[PARC Universal Packet|PUP]] [[protocol suite]].

Although remote [[file]] access was the principal service provided, an IFS server provided several other services over the network, including [[email]], [[directory]], time, and a number of others.

Developed by [[Xerox PARC]], it ran on a [[Xerox Alto]], using T-80 or T-300 [[Trident disk drives]] to hold data.

It was designed in November-December 1976, began testing operation in January, 1977, went into what was effectively 'beta' release in June, 1977, and had its first full release in August, 1977. It was called 'Interim' because "improved facilities are under development", but those never appeared, and IFS soldiered on within the [[Xerox]] corporate [[internetwork]]. Major IFS servers within that internet were:

{| class="wikitable" style="text-align: center;"
! Name(s) !! Organization
|-
| Ivy || PARC (Palo Alto)

|-
| XEOS || EOS (Pasadena)
|-
| ADL || ADL (El Segundo)

IFS servers, pre-loaded with software, documentation, etc were also provided to the universities which received a grant of a package of PARC-developed technology in 1978.
